A modelling study of the performance of conventional diffused P/N junction and heterojunction solar cells at different temperatures

Conventional crystalline silicon (c-Si) diffused P/N junction solar cells remain the largest contributor to solar electricity. In order to retain a high efficiency and as well, reduce the cost of solar electricity, Sanyo has proposed the “heterojunction with intrinsic thin layer (HIT)” solar cells where the emitter and the back surface field layers are deposited using low temperature (
