How do solar panels work? – Richard Komp

View full lesson: https://ed.ted.com/lessons/how-do-solar-panels-work-richard-komp

The Earth intercepts a lot of solar power: 173,000 terawatts. That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? Richard Komp examines how solar panels convert solar energy to electrical energy.

    I do not understand this thing about fullfilling the world’s power consumption need… there more power is available the more we will use.. it can never be fullfilled…

    Doing this for school:(

    jooooon

    It’s possible to power a train by purely solar energy. In Australia, a 1.25 kilometre straight and flat railway uses a 1940s converted DMU powered by solar panels on the roof. Don’t get too excited though, as it needs heavy sunlight, ideal running locations and it can’t go very fast. Don’t expect to see them on the London Underground any time soon.

    ok

    I truly ask myself some wacky questions, but thanks for answering this lingering thought i had!

    Thank you Ted x , for making the concept simpler
    👍

    Super late but how do you string DSSCs together in modules? Would really appreciate any help thank you so much.

    Saudi Arabia there having the perfect location for infinite oil + infinite solar power.

    I wonder if it would be possible to have a giant ring of solar panels in space around the Earth so that there are always panels facing the Sun 24/7. Right now it’s definitely not too feasible as I imagine the logistics of it (i.e. distributing the power generated back down to Earth and to consumers) is a nightmare, in addition to the challenge of construction as well as security (e.g. risk of space debris colliding with the panels and damaging them).

    Hi

  15. Teen jun wen on December 4, 2020 at 9:57 pm

    What if Solar panel+heat converter

    thank you ! this helped me in my project❤❤

    I’ll tell you how these bird Terminators work a k a solar power plant the innocent bird flies within the vicinity of the solar power plant is that KFC in mid-flight which are called by the employees at the solar plant streamers as the innocent bird catches fire and smokes all the way down till it hits the ground it won’t matter after eight years we won’t have any more birds so they won’t be nobody to complain

  18. Z McCutch on December 4, 2020 at 10:05 pm

    WOW!! I didn’t know that Earth could take that much solar power.

  19. Tagore on December 4, 2020 at 10:06 pm

    Very Informative &well explained Video about Solar cell. Thank you Ted Ed Team

  20. Fatıh Kılıckaya on December 4, 2020 at 10:06 pm

    The efficent of solar cells can be ignored. Eventually the Sun does not demand salary.

  21. Khaleesi Romaerys on December 4, 2020 at 10:12 pm

    We need solar panel phones so that we can have full batt anytime we want without charging it!

    "You can think of light as the flow of tiny particles, called photons…"

    Physists: "well… …not exactly, no."

  27. Miguel Rodriguez on December 4, 2020 at 10:18 pm

    I just had solar panels installed at home. I live in Florida so it’s a no brainer. I’ve been very happy with them so far. I just wish our state used much more solar energy.

  28. Harrow on December 4, 2020 at 10:19 pm

    I thought that it took electrons from the photons

  29. Pi61 on December 4, 2020 at 10:19 pm

    I noticed that the p-n junction in the video created the electric field incorrectly. the N type semiconductor gives away electron, which produce positive electric field, rather than negative. the same thing goes to the P-type semiconductor

    What is the name of the graphic visuals used here called? eg. Vector. Please help thanks!

    Nice teaching and I think so much

  33. Arya Susila Nugraha on December 4, 2020 at 10:27 pm

    Indonesia really needs solar panels at every house but u know coal and oil bussines prevent government to do that

  34. NYCamper62 on December 4, 2020 at 10:27 pm

    I’ve been using solar at my camp for about a decade now. Lights, refrigeration, charging phone etc. The tool battery charger & stick vacuum require the inverter but everything else is 12v, even the laptop (12v to 19.5 converter). Solar IS my generator, it keeps my battery bank (4x 6v GC2 in series – parallel) in good shape for about 400 aH reserve.

    This was great, I have been researching "how much can i save with solar panels" for a while now, and I think this has helped. Ever heard of – Aanarter Exceptional Ascendancy – (do a search on google ) ? It is a good exclusive product for discovering how to learning how to get free power minus the normal expense. Ive heard some super things about it and my cousin got excellent success with it.

  37. boomer on December 4, 2020 at 10:36 pm

    If anyone wants solar on their home hit me up! I just got solar on my house and can refer you to an amazing company here in the US! Im already paying a lower bill than before😁🙏🏼

    I make presentation about solar cell just from here, and that’s enough
    I really satisfied with this video 😀

    This is glorious, I have been researching "3 ways electricity can be produced" for a while now, and I think this has helped. Ever heard of – Diyadison Penhloe Blaster – (do a search on google ) ? It is an awesome one of a kind product for generating your own electricity minus the hard work. Ive heard some extraordinary things about it and my friend got excellent results with it.

    Winner of a video, been searching for "how much money do solar panels save per year" for a while now, and I think this has helped. Have you ever come across – Aanarter Exceptional Ascendancy – (just google it ) ? It is a great one of a kind product for discovering how to learning how to get free power without the headache. Ive heard some unbelievable things about it and my mate got excellent success with it.

  44. Hjalmar Nofors on December 4, 2020 at 10:40 pm

    A thought occured while watching the video.

    Couldn’t we put solar cells on the earths poles? The days there are very long and during summer the sun doesn’t go down at all. I also know that during winter the nights are very long. But couldn’t the energy from the other pole even that out?

    Great video btw!

  45. Dave Smave on December 4, 2020 at 10:40 pm

    Ok sure I’m all for solar but you can’t just block out the Sahara and destroy an ecosystem
