Simulation of a novel single junction thin film solar cell

A novel single junction thin film solar cell structure ITO/p- a-Si:H /i1- a-Si:H/i2- μc-Si:H/n- μc-Si:H/ITO is studied with Silvaco TCAD tool in this paper. The simulation data predicts that the thickness of the maximum conversion efficiency is between 250–500nm. For the best efficiency, the intrinsic μc-Si:H layer is predicted between 1500–2500nm. The results indicate the conversion efficiency is higher than that of the conventional amorphous silicon solar cell 7.53% and 8.14% for the conventional microcrystalline solar cells. To compare with the nanocrystalline (nc-Si:H) heterojunction thin film solar cell, the conversion efficiency of the proposed structure is increased more than 21.92%.
