COMPUTER SIMULATION OF p-a-Si:H/n-c-Si HETEROJUNCTION SOLAR CELLS
The performance of p-a-Si:H/n-c-Si heterojuction solar cells is simulated by AFORS-HET software, a numerical computer simulation program for modeling heterojunction solar cells. This numerical approach leads to a better view of the transport mechanism and a better understanding of the heterojunctions behavior for heterostructure solar cell based on n-c-Si. We use doped n+ layer into heterojunctoin solar cells and it can be realized by inserting an heavy dopted n+-c-Si layer on the back of the n-c-Si substrate in simulation. This layer improves the Ohmics contact with the metal contact and also gives the back surface field effect. By doing this, We found the spectrual response of the solar cell in long wave region became better. With the increasing of the doping density of the n+ layer, the performance of the solar cells increased significantly. The best efficiency for a-Si/i-a-Si:H/n-c-Si/ n+c-Si soller cell is achieved to 24.35%.
