Table Photoconductivity of [PcSi(eda)]n-PVDF thin film CTM E.10-5(V/m) In the light, a semiconductor may conduct – Will conduct if photon energy can bridge gap – Blue … WebPhotoconductivity When light of sufficient energy is absorbed by a semiconductor, the number of free electrons and holes changes and raises the electrical conductivity of the semiconductor. This increase is called photoconductivity and is dependent of the excess electron and hole concentrations and their mobility via the following equation.
