density, μp is the hole mobility and dp is the hole diffusivity. q is the electronic charge and e is the electric field. note that in this section we use e, e^ and e→ interchangeably for the electric field. its a mistake and we should be consistent and stick to e. the transport equations describe how carriers...

the p-n junction and therefore contribute to the light-generated current, but probability depends on the distance that a light-generated carrier must travel compared to the diffusion length. collection probability also depends on the surface properties of the device. the collection probability of carriers...
