Analytical model and photovoltaic parameters improvement of polysilicon solar cells with porous silicon emitter

•A simple model was developed to simulate the performance of polysilicon solar cell with PS emitter.•The PS layer can result in a decrease in emitter reverse saturation current density.•It also induces an increase in solar cell photovoltaic parameters.•The emitter region should not be treated as a ‘...
