Can Infrared Crystal Radios Self-Power Like Solar Cells?

[James Kidder]

Can a crystal types radio be made to work in infrared? With an antenna of lead sulfide or lead selenide perhaps?

You're not going to have much luck using an antenna to pick up infrared, period. Its frequency is just way too high.

Tell us what you are attempting to do and it is possible we can suggest something else.

You could just use a photoresistor-type infrared detector. They look like LEDs and you can get them from most online electronics stores. You can't use antennas regardless of their composition as antennas are designed for receiving lower frequencies in the microwave and radio range.

I would like something that would make its own power like a solor cell/laser or radio/crystal radio.

Once again, what are you trying to accomplish? No one is transmitting anything on infrared radiation.

Well there are infrared/visible sensitive solar cells. Why do you want to be able to just capture infrared?
