Modeling of charge transport in thin film silicon solar cells using light generation distribution from full wave EM simulations

The continuity and Poisson equations were modeled in different layers of thin film silicon solar cells using finite difference method. In each layer the system of equations were solved numerically. The mesh size was chosen to be smaller than the Debye length. Different parameters like energy bands, electron and hole concentrations, electric field, voltage, current densities etc. were calculated at each mesh point. Cell parameters were calculated using the generation rate obtained from optical modeling.
