Summary:A theoretical 3D study on the diffusion capacitance in a polycrystalline silicon solar cell under steady multispectral light and various incidence angles is carried out. The effect of grain size, grain boundary recombination velocity and illumination incidence angle on the diffusion capacitance is then presented and analyzed; the dark capacitance of the cell was also calculated. Finally, considering the junction of the solar cell as plane capacitor, the efficiency is evaluated. The effect of grain size, grain boundary recombination velocity and illumination incidence angle have been discussed, based on the open circuit and short circuit capacitance modes.
