Abstract
To obtain higher conversion efficiency for HIT (Heterojunction with Intrinsic Thin film) solar cells, an effective way is to use μc-3C-SiC:H with a wide bandgap as the cell emitter. In this paper, a simulation study is carried out for the HIT solar cells with μc-3C-SiC:H emitter. The performance of solar cells with μc-3C-SiC:H emitter is compared with that of solar cells with a-Si:H emitter. For a 10 nm-thickness emitter, the cell efficiency can realize an increase of above 1.0% for the use of μc-3C-SiC:H. The main cause for the improvement is the reduction of optical loss in short-wavelength region.
