Modeling an a-Si:H/c-Si Solar Cell with AFORS-HET

Abstract

The physics models and material parameters needed to simulate an a-Si:H/c-Si solar cell with AFORS-HET are discussed and a simulation study showing solar cell characteristics subject to emitter doping, i-layer thickness and interface quality is presented. The AFORS-HET user interface is introduced so that the interested reader can repeat the simulation study. It is explained in detail how to define a structure and how to simulate a solar cell under different external conditions such as external current, voltage and illumination and how to calculate I-V curves to obtain solar cell characteristics.
