Optimization of structure and process parameters of PERL (Passivated Emitter Rear Locally Diffused) silicon solar cell using SILVACO software package has been carried out. PERL single junction silicon solar cells are reported by researchers to have high efficiency (~ 20-25 %) and are promising for further improvement. Optimization is based on process and device simulation in SILVACO software package and integrating a Response Surface Methodology for optimal solution. Optimization of texture dimensions and ARC is followed by process parameters optimization for the emitter and base for best performance solar cell. A solar cell of efficiency 24 % is demonstrated by the simulation.
