I was sent here from sci.electronics design, so if I'm
asking a question that's in a FAQ someplace, please point me
there.
I've been trying to find out what part of the spectrum
your common silicon cells scavenged from calculators best
convert to current, but the best I've been able to find
after Googling myself silly is the fact that the bandgap for
silicon puts their sensitivity peak in the near-infrared.
Some claim that such cells are antireflection-coated
which would explain the different colors they come in, but
others claim that's just a moisture barrier and the most
efficient ones are dark blue, which makes sense if they like
NIR best.
Why do I care? I want to hide some cells behind fake
gemstones for a project. If the cells do prefer NIR, it's
going to make it interesting to find fake stones that will
pass enough NIR to be worthwhile. Not impossible, it just
means I get to do a lot of testing.
Is there anyone/a site that can set me straight, or am I
doomed to the tedium of finding out for myself?
TIA
