Abstract

In this study, the effect of varying the corresponding thicknesses of p-type and n-type contact area of single junction silicon solar cells has been investigated. The simulation has been carried out using Silvaco TCAD. Several samples were created and the effects of each solar cell were analyzed. The result shows that thinner solar cell gives higher photogeneration efficiency (64%) due to higher carrier generation near the incident surface while thicker combination of p-type and n-type thickness produce lower photogeneration efficiency (59%) due to the reduction of photogeneration rate in deeper area. The photogeneration rate is decresing in exponential term when distance or thickness increase.
