What idont understand is how the electric filed is created when the n typed
material comes in contact with p typed?

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.

Thank you. Very helpful

Good explanation but I don’t understand if you remove the elections and it
becomes ionised won’t it stop working how can something keep giving away
it’s electons?

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.

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!

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

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

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

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

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.
