Miniature Solar Cell - BPW34

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.Features:Package type: leadedPackage form: top viewRadiant sensitive area (in mm2): 7.5High photo sensitivityHigh radiant sensitivitySuitable for visible and near infrared radiationFast response timesAngle of half sensitivity: phi = ± 65°Lead (Pb)-free RoHS compliantDimensions:5.4x4.3x3.2 mmDocuments:Datasheet
