In photovoltaic detectors, or photodiodes, the semiconductor layer is composed of InAsSb or InAs materials. Charge carriers produced by absorbed photons accumulate at the photodiodes, which have complex current-voltage properties.
The detectors can either work with reverse voltage or at flicker-free zero bias. Such detectors are mercury-free and cadmium-free. The detectors therefore fulfill the RoHS directive and are suitable for the consumer market.
