Back passivation of CdTe solar cells was done using silicon di oxide (SiO2) and silicon nitride (SiNx) and its effect was seen on dark I-V, light J-V and C-V characteristics. We also did the annealing of solar cell which further changes the performance of solar cell. Solar cells show enhancement in performance with SiO2 passivation and annealing after SiO2. There is no enhancement in performance with SiNx but it improves by doing annealing after SiNx.
