Modeling of thin film solar cells: Uniform field approximation
TLDR
In this article, a model of a thin-film solar cell is presented that can be easily used to analyze solar cell properties and the continuity equations are solved using the regional approximation, producing elementary solutions that give insight into the physics of the transport in the cell.Abstract:
A model of a p‐i‐n thin‐film solar cell is presented that can be easily used to analyze solar cell properties. The continuity equations are solved using the regional approximation, producing elementary solutions that give insight into the physics of the transport in the cell. The steady‐state solutions are compared with measurements on typical hydrogenated amorphous silicon, a‐Si:H, solar cells. The ac solutions are used to explain a new source of photocapacitance due to mobile carriers.read more
