Webphotodiode is the bandgap energy E g of its active region. The photogenerated electrons and holes in the depletion layer are subject to the local electric field within that layer. The electron/hole carriers drift in opposite directions. This transport process induces an electric current in the external circuit.
WebEquivalent Circuit for the silicon photodiode Shunt Resistance, R SH Shunt resistance is the slope of the current-voltage curve of the photodiode at the origin, i.e. V=0. Although an ideal photodiode should have an infinite shunt resistance, actual values range from 10’s to 1000’s of Mega ohms.
