Figure A. Band diagram illustration of the photovoltaic effect. Photons give their energy to electrons in the depletion or quasi-neutral regions. These move from the valence band to the conduction band pending on the location, electrons and holes are accelerated by E drift, which gives generation photocurrent, or by E scatt, which gives scattering photocurrent.
