Amorphous silicon solar cells generate 15 mA/cm2 density of current and the voltage without connected load is above 800 mV. The efficiency is between 6 and 8% (S. W. Glunz et al. 2006). But, all solar cells require a light absorbing material contained within the cell structure to absorb photons and generate electrons (G. Sissoko et al. 1996).
When temperature increases; I sc remains constant whereas P max and V oc decreases. These optimum values enhance the efficiency and fill factor of the silicon solar cell. Simulations in PC1D is an effective way to enhance the performance of silicon solar cell. 1. Introduction
Basic silicon solar cell has been designed and simulated using PC1D simulator. Optimum values for the thicknes of base layer and temperature have been decided from I-V and P-V curve of basic silicon solar cell. It has been observed that as thickness increases, I sc increases whereas P max and V oc decreases.
The output power of the PV cell is voltage times current, so there is no output power for a short-circuit condition because of VOUT or for an open-circuit condition because of IOUT = 0. Above the short-circuit point, the PV cell operates with a resistive load.
