Looking for thermophotovoltaic cells...

[hellokitty[hk]]

Hello everyone!

In my last thread, I asked about an affordable (very cheap, relative comparisons, same light tint) luxmeter in preparation for science fair...



Now I put my faith in CPF with this request:

I'm looking for thermophotovoltaic cells, the ones that absorb infrared radiation.

I've looked around and couldn't find anyway...



It might be a tough request though...Thank you so much in advance!
