This panel can put out close to 100 watts kzread.infoUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.

Difference between you and other KZreadrs is your not lazy. You have no problem moving the camera 65 thousand times for the viewers and you also take pride in the videos you make. Keep up the good work sir!

Hey!!! Big fan here!!!

Simply the best animation ever for a solar cell operation !

No extra stuff...no extra music - JUST PERFECT! a beautiful animation with apt explanation...really loved it- I had no distractions or au other thoughts while watching it

Saw a solar panel up close for the first time. Fascinated me so I had to go and learn how they work. Your video was extremely good at explaining why and how solar panels work from beginning to end. 👍🏻

This was a phenomenal video. I didn't think I'd really understand the topic, but this was very easy to digest. Can't believe it took me years to find this gem. Thank you!

Great explanation. Finally got the whole concept including the role of semiconductors and doping.

This was perfect! This literally explains most of the chapters in my textbook in a super clear way (Lattice Structure and Bonding, Drift Current, Generation and Recombination, Photoexcitation, Conductivity, etc)

Possibly the best and most detailed video on solar cells that I've ever stumbled upon. Great work!

I'm still very impressed with the ingenuity of the people who had the idea to cook up semiconductors like described in this video... and the people, who saw the potential, like 70 years ago.

A clean and crystal clear explanation... Indeed interestingly gets everyone attention to the fullest - like you guys are really going straight into our head, while watching this, I didn't really have any second thoughts

Highly appreciated!😊👍 great info. Thanks and accept blessings.

Thank you for the video ! Can someone explain to me why the electrons generated by the light energy crosses the depletion region into the N-side ? The field favors that direction; but the field is only present in that direction within the depletion region right ? Beyond the depletion region, in the N-side, electrons would want to stick around the positive ions in the depletion region. So why does it move toward the terminal in the N region (Away from the positive ions) ?

@BlackRockExecutive

2 жыл бұрын

Probably two years too late now but here it goes. Imagine now the electron has travelled to the n side, with that one more electron at that n side. The n side is initially charge neutral. This electron pertubs the charge balance of the n side by making it more negative. The positive and negative "forces" don't equal now. So the sensible thing is to kick an electron out into the external circuit to maintain back its charge balance. If you are interested to learn more about solar cells in an intuitive and fun manner, I'm starting a video series called "Shining Light on Solar Cells", covering the a-z of solar cells.

Good to know that here in india the solar power percentage is more than 10% of the total energy input.. seeing the potential of solar energy here in the country along with the rapid infrastructure already getting in place, we can really expect solar energy to be the next form of energy for the nation and the world too...

I didn't quite understand why the holes and electrons formed in the depletion region were moving in their given directions. The electrons moved over to the negatively charged side which already had an excess of electrons, which seems like the opposite of what should happen.

@Kanglar

5 жыл бұрын

@@fonduman213 It is kind of confusing. The important thing to note is that the P layer and N layer have NEUTRAL charge to start out with. The P layer (green holes) is not positively charged, it simply has atoms with the electron structure that allow it to accept electrons and become negatively charged. So when the depletion zone forms, the area of the P layer in the depletion zone is actually negatively charged, in other words it was neutral and has now accepted electrons. So when more green holes pop up, the go to the negative charge which is the P layer, and all the green holes stack up and flow through the load. You can probably get a better explanation than I can give if you look up how a diode works, which is literally what a solar cell is; a bunch of PN junction diodes.

Thank you! I didn't do too well in physics but this explained the concept really well.

I was doing some reading about the James Bond Movie: The Man With The Golden Gun on TV Tropes and Idioms. They mention that the villain: Scaramanga, has Solar Cells that operate at 95% efficiency. They mention that the best that solar cells currently get is 25 to 35%. They added that if solar cells really could operate at 95% efficiency, then all other power sources would be obsolete and the energy crisis would be solved. We'd have all the power we'd ever need. Hopefully they'll achieve that soon. Imagine, you'd have solar panels on your roof and never have to worry about running out of power. You could have them on your vehicle and never have to worry about recharging the batteries. Vehicles of every type, except submarines, could be solar powered. Even jet aircraft, since there is a such thing as electric jet engines. The problem with them right now, is the batteries can't hold enough power to allow them to fly the same distance or further then standard jets. Too bad.

Solar energy could be stored as H2. This is, in a way, already in practice when H2 fuel is produced.

Now that there is a depletion region with an electric field (Shown at 2:55, being positive on the n side and negative on the p side), the electron and hole pairs generated at the depletion region would separate according to this electric field, and hence electrons would travel to the more positive n side of the depletion region.
