Description: The BPW34 is a tiny, general-purpose PiN photodiode. This photodiode has a ton of uses, one of which is to use it is a mini solar cell to power your project. The cell is sensitive to a wide range of light wavelengths (430-1100nm), so it should produce power in a number of different settings. The rated open-circuit voltage is 350mV (900nm, 1mW/cm2 light source), and short circuit current is 47μA.
These are fun (of course)! We shined a 940nm infrared LED on one of them and it produced about 0.5VDC open-circuit voltage. Stringing four together in series, we were able to turn an LED on with them. They’ll also produce a small voltage, ~250mV, in a brightly, fluorescent-lit room.
