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

    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!

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

  6. Tommy Anderson on April 16, 2021 at 12:14 am

    Cool videos! Keep going!

  7. João Dalvi on April 16, 2021 at 12:15 am

    Actually its 127V

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

    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.

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

    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:

  13. AlphaNoob on April 16, 2021 at 12:22 am

    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.

  14. Joseph Salomone on April 16, 2021 at 12:22 am

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

  15. Jocelyn Joseph on April 16, 2021 at 12:23 am

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

  16. John Nicholson on April 16, 2021 at 12:24 am

    To bad you did not say Einstein, photoelectric effect, and Nobel prize.

    What if we used conductors instead?

  19. JITENDRA CHANDRAVANSHI on April 16, 2021 at 12:26 am

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

  20. Tingting Hao on April 16, 2021 at 12:28 am

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

  21. John Bonahoom on April 16, 2021 at 12:30 am

    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.

    thank you i was wandering how that work

    Turn off the radio in the background next time

  25. Sanjay on April 16, 2021 at 12:34 am

    It’s Same as transistor

  26. Thread Bear on April 16, 2021 at 12:34 am

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

  27. Julie Jones on April 16, 2021 at 12:36 am

    Absolutely brilliant thank you x x

  28. Zachary Simpson on April 16, 2021 at 12:36 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

  29. S W on April 16, 2021 at 12:38 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.

  30. DJ dal on April 16, 2021 at 12:38 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

  31. proto type on April 16, 2021 at 12:39 am

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

  32. Raida Hasan on April 16, 2021 at 12:41 am

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

  33. Tharan Js on April 16, 2021 at 12:43 am

    good but so fast u ….

  34. iamzimbabwe 36 on April 16, 2021 at 12:45 am

    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!

  36. Alaap Jagdale on April 16, 2021 at 12:46 am

    Really nicely explained 👏👏👏

  37. mr nothing on April 16, 2021 at 12:47 am

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

  38. SangHarsh Nirvana on April 16, 2021 at 12:49 am

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

  39. Elmārs Spalva on April 16, 2021 at 12:49 am

    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…

  40. M_S_ H on April 16, 2021 at 12:50 am

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

  41. Anshuman Sinha on April 16, 2021 at 12:52 am

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

  42. Thomas Edelberth on April 16, 2021 at 12:52 am

    Your videos are amazing. Thank you very much!

  43. Maryam Almansouri on April 16, 2021 at 12:52 am

    What does the solar powered clone represent in the video?

  44. GrumpyGrampa on April 16, 2021 at 12:54 am

    Great explanation of semi conductors

  45. Daryl Kyte on April 16, 2021 at 12:55 am

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

  48. trenten ragas on April 16, 2021 at 12:58 am

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

  49. James Alexander Jimenez-Medina on April 16, 2021 at 12:59 am

    You sir are awesome….

  50. Prince Mark Alvarez on April 16, 2021 at 1:00 am

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