How to make solar battarys?
Question:
Answer:
Are you asking about making your own solar cell? It is very difficult to make a solar cell. There are some web sites that show you how to make a wet solar cell just for the fun of it, but the efficiency is abysmal. Even commercial solar panels range from 5% to 15% efficiency. Supposedly, the best commercially available panel is 21% efficient. There are some research panels that are reported to be in the 40% range, but they are not available for commercial even if you could afford it.
Then for commercial panels, in decreasing order of efficiency there are:
monocrystaline panels
polycrystalline panels
and amorphous silicon panels
I lived for 2 years in a remote area where my only electricity came from a wind generator and 2 monocrytalline panels. My panels were abut 3 sq ft area each and they were 50 watt panels. (about 15% eff.)
Polycrystalline panels of the same size would yeild around 25-30 watts.
Amorphous silicon panels of the same size would yield around 5-15 watts.
