Photocell
A much faster response can be obtained with a photodiode. As with a photocell, a photodiode operates by photons "kicking up" electrons that allow current to flow, but unlike a photocell, current can flow even without an externally imposed voltage due to the electric field in the diode. In response to a rapidly changing light source, this ...
