Grain boundary assisted photocurrent collection in thin film solar cells

Grain boundary assisted photocurrent collection in thin film solar cells

The influence of absorber grain boundaries on the photocurrent transport in chalcopyrite based thin film solar cells has been calculated using a two dimensional numerical model. Considering extreme cases, the variation in red response is more expressed than in one dimensional models. These findings...
