This tiny photodiode (BPW34) 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. They'll also produce a small voltage, ~250mV, in a brightly, fluorescent-lit room.
- Radiant sensitive area: 7.5 (mm2)
- High photo sensitivity
- High radiant sensitivity
- Suitable for visible and near infrared radiation
- Fast response times
Dimensions: 5.4x4.3x3.2 mm
