    If we really need electric energy lets cover some parts of the sun to create power

  2. iamzimbabwe 36 on March 23, 2021 at 11:18 pm

    This was such a fantastic explanation. I’m actually shocked at how good it was. You’re doing a hell of a job with this. Thank you!

  3. AlphaNoob on March 23, 2021 at 11:20 pm

    Question: Per Square Meter the Sun is giving us 1000w per hour? or Per Second? I ask because solar panels are rated a number a Watts per hour.

  4. Nitika Dhawan on March 23, 2021 at 11:20 pm

    What if we used conductors instead?

  5. trenten ragas on March 23, 2021 at 11:21 pm

    wouldn’t the square inverse law mean the solar power would differ for altitude?

    What does the solar powered clone represent in the video?

    This video is really good. I was looking for a video which would explain how solar panels work and it’s very useful

  9. SangHarsh Nirvana on March 23, 2021 at 11:24 pm

    Most of your videos are indoors. It would be refreshing to see you in outdoors sometimes.

  10. mawada 2020 on March 23, 2021 at 11:26 pm

    thank you i was wandering how that work

  11. UnspokenOwl on March 23, 2021 at 11:26 pm

    I noticed you too, sometimes use the wide periodic table version, just gotta say tho Nick, hope you know of this bad boy site, thats a nice table site 🙂 They have a wide one here too that is pretty good for download, but their interactive stuff is legit!

  12. Jocelyn Joseph on March 23, 2021 at 11:27 pm

    Turn sunlight energy into electrical energy. SiP:SiB junction allows electrons to be donated across like a one-way valve, generating the potential / current.

  13. Tingting Hao on March 23, 2021 at 11:28 pm

    Thanks for the excellent explanation, great for kids to start the science lectures!

    God now i know why i learn All of these stuff in my sxhool now, now i know

  16. Tommy Anderson on March 23, 2021 at 11:29 pm

    Cool videos! Keep going!

  17. Suleyman Eliyev on March 23, 2021 at 11:29 pm

    Ета уже старая технология

  18. Alaap Jagdale on March 23, 2021 at 11:29 pm

    Really nicely explained 👏👏👏

  19. Thomas Edelberth on March 23, 2021 at 11:30 pm

    Your videos are amazing. Thank you very much!

  20. mr nothing on March 23, 2021 at 11:31 pm

    the best video ever! so funny in a naturally acting way.. which just feels good. well done man!

  22. Joseph Salomone on March 23, 2021 at 11:33 pm

    I actually didn’t know that’s how they make N-type and P-type silicon. Cool!

    "Balanced, as should be"
    Thanos was wrong

  24. Daniel Prieto on March 23, 2021 at 11:37 pm

    Would having a higher percentage of and phosphorus and boron increase the amount of energy the cell produces

  25. The Science Asylum on March 23, 2021 at 11:39 pm

    Anyone whose looking for more videos on global warming, climate change, and/or renewable energy, I can’t recommend PBS Hot Mess enough. One of the hosts is a friend of mine and she really knows her stuff:

  26. Tharan Js on March 23, 2021 at 11:39 pm

    good but so fast u ….

  27. Priscilla Allen on March 23, 2021 at 11:40 pm

    But what happens to the critters; meerkats, birds etc. who got eviction orders.

  28. Sanjay on March 23, 2021 at 11:43 pm

    It’s Same as transistor

  29. GrumpyGrampa on March 23, 2021 at 11:43 pm

    Great explanation of semi conductors

  30. JITENDRA CHANDRAVANSHI on March 23, 2021 at 11:47 pm

    This is what happens, when a shear funny person who happens to be a science expert, teaches you physics.

  31. Aronov Shmuel on March 23, 2021 at 11:47 pm


  32. Daryl Kyte on March 23, 2021 at 11:47 pm

    What would happen if you use a mirror as the metal plate? Would that capture more light energy?

    Turn off the radio in the background next time

  35. Zarina Willows on March 23, 2021 at 11:56 pm

    Nick, you are my favorite person on YouTube.

  36. James Alexander Jimenez-Medina on March 23, 2021 at 11:58 pm

    You sir are awesome….

  37. Raida Hasan on March 23, 2021 at 11:58 pm

    So if there is no sunlight on it then no energy mmmmk

  38. Elmārs Spalva on March 23, 2021 at 11:59 pm

    Hold on… so why is it being cancelled out in the first place? Since in order to cancel out, you need it to reflect in two places anyway, how does it help the efficiency? I’m confused…

  39. Zachary Simpson on March 24, 2021 at 12:00 am

    I’d like to give an idea of adding another thing to the solar panels power into DC when filling power to the batteries and since thats already done, I had a question of adding something to the power. Respond to me so I can talk to you personally

  40. proto type on March 24, 2021 at 12:01 am

    Ahh, it’s a diode getting some kick from photons

  41. mayron gustavo on March 24, 2021 at 12:01 am

    Melhor canal dedicado à física no YouTube.

  42. S W on March 24, 2021 at 12:02 am

    Liked the video. I am searching for a way to compare apples and apples, sort of speak. Such as, if I need to power a 17.5k BTU AC unit on a RV. How many cells or arrays it would take to do so. Do I need a way to store electrons within a battery such as a lithium ion battery then use the battery bank along with the solar array panels to run the AC. Or is this technology meant for something more like a set up to recharge the battery on my watch, computer, or a fan rather than an AC unit? I would like to have the knowledge to speak about the utility of such technology. Love the technology but I would like to dive deeper into solars’ utility. Thanks again.

  43. Nikhil 17bt0530 on March 24, 2021 at 12:03 am

    Isn’t caesium used which needs less energy to lose electrons

  44. Mark Bates on March 24, 2021 at 12:03 am

    How about explaining where the lithium and especially cobalt for your battery comes from.
    Explain why you have to mine 500,000 tons of rock for one Tesla battery. That has a very limited lifespan of efficiency.
    Then let’s figure out the amount needed to furnish everyone in your hometown one Tesla battery.
    Now let’s do the math for one battery for everyone in the United states.
    Now we only need 6,000,000,000 more for the rest of the world.
    Does this sound green.
    I would really like an answer.
    Not just from you but the rest of the solar proponents.
    I’ll look forward to seeing your conclusion but I won’t hold my breath.
    Very disappointed in you not investigating the situation before verifying alternative solutions.
    Without subsidies both solar and wind energy would be a non starter.
    No way can we upscale batteries for broad use at this time.
    With out energy storage we still need a full functioning conventional electric grid.
    If you have a solution let’s hear it.
    But please don’t spread disinformation about scalability of solar.
    All this does is hurt the industry in the future.

    I had a job at a company called Sunpower. They have developed a "super cell". What they do is buy solar cells from Asia. They then devide each cell into 6 equal straps. Then, in the next sequence these straps are glued back together, with silver oxide glue, into 6 foot lengths. Then build a standard 4×6 foot panel. In testing the product, they achieve up to 400 wats of power in each panel. They notated each panel by its output. Rather incredible.

  46. Thread Bear on March 24, 2021 at 12:07 am

    Hey. This is the best explanation of how solar panels work I have found on YouTube. Thank you. It really helped.

  47. DJ dal on March 24, 2021 at 12:08 am

    I will never look at solar panels the same, this video has provided me with so much detail and knowledge that I comprehend and no, I won’t look at them the same anymore, I will look and understand them <3

  48. João Dalvi on March 24, 2021 at 12:09 am

    Actually its 127V

  49. Anshuman Sinha on March 24, 2021 at 12:10 am

    Can you explain all this again but by treating light from the sun as a disturbance in the electromagnetic field?

  50. Julie Jones on March 24, 2021 at 12:11 am

    Absolutely brilliant thank you x x
