Abstract

Thin film silicon solar cells are optimized to increase their efficiency. One technique to obtain higher efficiency is to increase path length of light using textured surfaces. The impact of these layers on efficiency is usually studied using experimental methods. This requires building of a solar cell and is time consuming and prone to error. Simulation is used to predict light scattering effects in large domains with textured layers. We studied these effects using a conformal finite integration technique (FIT) that efficiently simulates complex geometries with surface roughness. The simulated external quantum efficiency EQE for a solar cell with a μc-Si:H and aSi:H layers with surface roughness are presented. © 2014 SPIE.
