  2. The solar panels only using photons (light) for power generation, but in
    tropical areas and in summer times lot of heat is produced, can we use that
    to boost up production? Thinking of a solar panel using both light and heat
    at the same time.

  7. Very simple to understand , thanks dude

  8. Dathotness4ya: I had that second question as well… I think what makes
    electrons leave shells where there are already holes is the fact that it’s
    the layer on the sun side, on the top side of the panel. When you imagine a
    solar panel glowing in hot sun, it sort of makes sense that this
    bombardment of energy on the layer with holes excites so many electrons
    that some of them make their way to the negative side even though it’s
    already saturated with electrons. And even though it isn’t completely
    intuitive, I guess they are stopped on the way back by the wall of happily
    paired electron-hole pairs which don’t want to change.

    And for the first question: I think the way to see it is that it isn’t
    Boron trying to bond with a fourth Silicon, it’s Silicon wanting to get
    it’s fourth electron from Boron.

  9. I am very interested in constructing my own solar power system. I know that
    the production of the silicon wafer is an extremely complex process but I
    would like to know how easy it would be to construct a solar cell with
    pre-purchased panels and how cost effective it is in comparison to buying a
    complete system. In my case the solar cells would be used to power lights
    for an indoor hydroponic system so I don’t believe it would be too power
    demanding. Any suggestions would be appreciated, thanks!

  10. How much Solar equals one amp of current? Or how much does it take to
    produce one amp of current when using solar?

  11. Awesome, thanks a lot

  12. helpful…also want to know how efficiency of solar cells, etc. is measured
    for comparison in the market place

  14. thanx man

  15. I’ve watched a couple other videos about the chemistry/physics of pv cells
    and this was definitely the clearest. Thanks for the vid

  16. Thank you, this will help me explain the mechanicle working process of my
    innovated solar prop.

  17. Informative video! thanks

  18. TWO MAJOR QUESTIONS: 1) Why does Boron try to bond with a 4th silicon if it
    only has 3 electrons (or maybe I need to refresh my knowledge of valence
    and orbital chemistry)? 2) Why would the electric field make the N-type
    side more negative and P-type side more positive? Why wouldn’t the now free
    electrons just travel to the positive P-type side to neutralize charge? The
    video was helpful up to these points, especially my second question. I
    think I’ll actually dislike this video.

  19. On the spot

  20. thanks for the information…very thorough… it was exactly what i was
    looking for…

  21. make a video about silicon doping process

  22. Thanks for your explanation!

  23. now is everything clear! Tnx!

  24. How does the electric field push negative electrons to the negative layer?
    Also, wouldn’t the extra electrons in the N-layer travel through the
    external circuit and fill the rest of the holes in the P-layer?
