Model optimization of nanocrystalline Si:H thin film solar cells

Photovoltaic properties of nanocrystalline (nc-Si:H) heterojunction thin film solar cells with the single junction structure of TCO/p- nc-Si:H/i1- nc-Si:H/i2- a-Si:H/n- nc-Si:H/AZO was studied by a computer modeling software AMPS-1D in this paper. Due to spectral response of solar cells with the examined nc-Si thin films as active elements showed a narrower spectral distribution and a blue shift comparing to pure amorphous solar cells. The results were higher efficiency than amorphous cells due to higher optical gap (higher output voltage) and better fill factor (higher mobility).
