Abstract :
In this paper the photocurrent properties of the CdS/CdTe thin film solar cell were modeled by using relative physical models that were the incoherence model of the optical generation, the continuity equation for carriers and the current density equation. Then the effect of CdS and CdTe thickness on the photo current was simulated. The results of the simulation show that: a optimum CdTe thickness were exited for a max photo current and thinner CdS thickness would reduce the optimum CdTe thickness and be helpful for improving the cell performance and lowing the cell cost.
