Been saying these same things for at least 15 years as well as taking a systems approach to our architecture, heat, water, cooling...basic needs. Flexible solar has been around since Jimmy Carter who didn't support it back then. It seems we always have to be in crisis mode before things can change. Glad to see this presentation, but wish there were more details on production costs and output efficiency...so people could get it. Thank you Hannah, your passion is shared by an old engineer.

It's not a crisis perse we have to be in. There also needs to be a good cost-efficency ratio, as well as a market/customers. And even a crisis wont make it magically possible to just change something. There are still poloticians who take bog steps in restricting green energy as much as possible for other big corps and/or because they are (please input your personal favourite word to describe people you hate). Germany for example has laws in palce how far away you can palce windmills from towns/cities and from one another, to not disturbe tha natural view. Which in comparrison how close you can place coal mines to towns (much closer) and destroy nature, is just a freaking joke. And this even while earth is (currently literaly) burning and there a re more catastrophes every year

Yes! I have dreamed of this technology and will hopefully be able to integrate it into my building designs in the near future!!!

Look up 'Organic Solar Cell'. The solid state physics gets complicated... but be patient and sit through it; it is really neat -- but it can't supply power for a country at 100% without a huge number of high energy density battery arrays.

Even if the current produced is less it is still a more efficient power source. Through ease of production and weight alone will make these cells more efficient and cost-effective. I would really like to learn more. Yes, the presentation was superb.

How much does it cost and how efficient it is and how easy is it to produce? The only questions that matter.

What is the efficiency of the ink? How much power does a square metre produce in direct sunlight? Given the thin layer, how much energy is absorbed at uneven angles?

The efficiency of (pure) organic solar cells is around 8% - 10% when it comes to comerce. Roughtly you get from one 1m² something around 50 - 60 Watt/h. Important here is, organic solar cells work better with less light then perovscites or Silicon based ones. Also, organic solar cells can be (technically) placed nearly everywhere on nearly every shape you want. So the area you can use to generate current is vastly bigger. Further whats in development are clear solar cells who could be used as windows. You can place organic solar cells on the tower of a windmill (Which has also been tested already). Wings I am unsure, cause you would need to think how to run the circuit over the moving parts

Amazing... Thanks Ted Talks

It's interesting. I have a few questions : how efficient is the conversion of light to electricity ? How polluting is the creation of that ink ? How do these panel age ? Once we dispose of those OPV, are they polluting ? Currently, silicon PV are relatively energy consuming to produce, relatively low efficiency, not so great of an aging material, and not recyclable and polluting once disposed of. Still better than charcoal.

Ben Saber oh, there's a good chance that's the case, but when I hear of a brand new technology supposed to save the world, I tend to be extra cautious, just because of things like "solar roadways" and other way people have found to exploit the need for environmentalism to con people out of their money. It's always good to ask about the downsides, the cost-benefits and the long term viability before jumping into something new. On what has been presented here, it seems a plausible thing that could exist and be beneficial, but this is TED, where companies go to make their promotion, not a science paper with details. they come to tell you how wonderful they are, not what are also their flaws, how far off they are from commercialisation, etc. Understand me well. I'm not saying it is bullshit, as I heard about them literally an hour ago. I am just cautioning that bullshit exist, and offer some axes of reflection regarding that. But it could be the next best thing since sliced bread, for all I know, and it sound promising.

Roger Toledo the "organic" she uses is the same one of "organic chemistry", the field of study of things based on carbon, including the fuel that power cars and polute through gigantic oil spills in the see. Beware of "organic" things. The term is almost as tricky as "natural". Uranium is natural, too. Same caution.

It's fascinating stuff and all, like many other TED talks inspirational, but I think solar cell companies have to shift the tone from an environmental standpoint - which is of course important but people are kinda tired of hearing -, to a more economical one. Because that's the thing building owners and construction companies will be convinced by and will invest on. It's a sad reality, but it is what it is. And I think the entire solar cell industry is mature enough and has been around for long enough to just put it out there. Put simply: how much investment we're talking about for a standard size building, how much more production has to scale to bring prices of those processes down, what sort of savings will those buildings have on a daily basis, what's the ROI, how much extra in construction costs we're talking about, what are the numbers for examples given, what's the maintenance cost, etc etc. And I know there are trappings in solar power production. It simply cannot generate as much power as more traditional technologies, but if it gets to a point where it makes sense to invest, then it should be enough for lots of people to adopt it. But it has to be presented in hard numbers. You need to get hard realistic studies of effects out there. Yes, solar is less poluting and all, but by how much? How poluting are the processes of creating said cells? How it's expected to scale with mass production? What are the advantages of having buildings producing solar power (like in an outtage, building will retain the ability to produce some power). What about batteries? And then stuff like, how much less CO2 is being put out by building a city full of buildings with solar panels? What jobs will it generate? What systems people are using to connect to the grid? Even if the answers are not totally great or favorable, people need to know. I think lots of people wouldn't mind a less efficient paradigm, and/or something that costs a bit more, given the benefits.

That is amazing! Solar can be everywhere without people even knowing! She's so pretty and smart I think I'm in love haha

The speaker failed to touch on the two main ingredients for a successful wide adoption of this technology; cost and efficiency. Lots of people are not willing to do massive investments that take a seriously long time to justify itself. And even more people are unable to do so. Solar panels still have a fairly low efficiency and require large and expensive installations to cover the power need of a normal home.

Hi. I do a bit of research in this field and wanted to answer your questions. Firstly cost: Organic solar cells currently cost almost the same as silicon solar cells. But that mostly due to lower demand. If production were to increase on the same levels as the current silicon solar cell industry, they would be much cheaper. Secondly efficiency: Organic solar cells have the drawback of not being as efficient as their silicon counterparts. You could say it's a trade-off from being more flexible, thinner, lighter and easier to manufacture. The other drawback is that they have a shorter lifespan than silicon solar cells. Additionally: The time it would take to get back the investment on organic solar cells have been estimated to be much lower (a couple of months) than silicon ones assuming the production scales up.

Very nice presentation

Very interested in this topic. It will be more efficient to extract the energy directly from the sun but there is the problem of the rotation of the earth.

Long overdue. Great and inspirational work by the solar energy researchers.

Production of silicon and the production of silicon solar cells is expensive and needs lot of energy and partly hightoxic substances (my education was in that field). These OPV here are insanely cheap to produce in comparison! Even if the efficiency would be only 1/5 of silicon solar cells, it would still be a great cost/efficiency rate.

Julia, i don't want to be rude, but if you have no clue about the costs and the current efficiency of organic solar cells, then why are you making these nonsense claims?!

Now if you took that ink and you made the solar cell and then you made a supercapacitor out of the same ink using thin aluminum and the ink itself, you could probably produce a panel that's flexible and does not need a battery and can run at a low milliamp for quite some time.

I want to use it for my self.. If the product is already in the market

What's the efficiency? Presumably it's less than 20% which silicon cells provide, though these may look prettier. Very efficient solar cells use multiple layers to harvest different wavelengths. The cost per watt could make these cells useful.

I only copy/paste the following from a company: "We already hold the world record of 13,22% cell efficiency for opaque (non-transparent) organic solar cells. In production, we currently achieve 7-8 %. The latest development allows transparency levels up to 30% with an efficiency of 6%. The intrinsic lifespan of our small molecules is >25 years (extrapolated)."

I opened this video in a tab, began listening to it prior to opening the tab. I was compelled to open the tab to verify I was no listening to a text to voice video. There is a lot of issues with material degradation to any laminate material, delamination, environmental ingress and mechanical damages etc. Better to genetically engineer a bio accumulator; skin a tree with organic technology from the DNA level, build into the tree a storage cell akin to electric eels and fish, then harvest the accumulated energy. Plant your solar generators where-ever there is soil and water and be confident that it will always face towards the best sun and will perform continual maintenance and repair to itself.

I wonder how efficient it is today compared to current tech. It's less that's a given but how much? Tech is great though, can do stunning and sustainable architecture.

Ubiquity of solar, fully distributed power, is the key goodness for society over time. Centralized power is never good, even when it's electricity or tyranny.

How effective is this technology? How many percent of the suns energy can it use? Most current photovoltaics cannot make use of more than 20 percent I think - is this better? If solar becomes more widely used, we definitely need to increase percentage of the suns energy that can be used! The technology does sound pretty versatile overall and should indeed open up new uses

Notice how all the stock blunders appear on TED Talks lol..Remember Theranos

10 years ago I remember a guy spearheading solar ink and he bought an old newspaper printing press to produce flexible panels in high volumes. It looked so promising but dissapeared.

Organic Photovoltaics are a cool concept but are not a new technology and are not commercially feasible at this point. According to the DOE: "The low efficiencies of OPV cells are related to their small exciton diffusion lengths and low carrier mobilities. These two characteristics ultimately result in the use of thin active layers that affect overall device performance. Furthermore, the operational lifetime of OPV modules remains significantly lower than for inorganic devices." Silicon based solutions are still our best option, as the presenter admits at the end.

So 5 years later, where are they?

Leather is a sustainable resource. Boots have there place to protect the foot. Therefore your opening point is mute.

Mine faveroit topic

I believe the majority of this and all ted talk audiences know enough about man’s devastating effect on our earth and it’s atmosphere in the last 100 yrs compared to anytime in earth’s natural history. We just need to apply the solutions NOW.

- The introduction lingers a bit, I know the enviroment is an issue, don't depress me now. - The Prius Effect suggests that aesthetics is a minor problem. People like evident bulky solar panels because it signals that they care for the enviroment. - You say cost effective? My family just cannot afford to install solar panels. I computed the return of investment and it is in the decades. In fact, an hybrid solar and wind power solution for the house is better, we just don't have the space for the wind turbine. Waiting for cheaper technology makes more economic sense at the moment. - Would this be cheaper? I don't know. Perhaps where you are. As I said, it makes sense to wait. At least my city uses geothermal energy, but a the country in general uses fossil fuels as main energy source. You can try selling me the idea that we can change the wolrd starting from our homes... but no, I do not have the resources to produce cheap solar panels in my house. And politics? Teach me to dismantle the corporations behind fossil fuels and corruption, and hopefully without creating a militia. That's a dislike from me. Fight me.

These concepts are nice, and they would actually work, but we are facing a major problem...our obsolete monetary system is not making it possible to widely spread these technologies. You can see this easily on the reality that corporations need to make profits from people and as such, there is no money for everyone as there are no jobs for everyone to cumulate income. We need world wide change of socioeconomic system from market driven capitalism to science driven natural law resource based economy.
