Optimized analysis of back-contact perovskite solar cells architectures

The perovskite solar cells with back-contact structure was reported recently that its carriers have a good diffusion length of 12 μm, which was considered as an innovational way to improve the cell's power conversion efficiency (PCE). Based on this reported experiment, the diffusion and drift o...

Summary:The perovskite solar cells with back-contact structure was reported recently that its carriers have a good diffusion length of 12 μm, which was considered as an innovational way to improve the cell's power conversion efficiency (PCE). Based on this reported experiment, the diffusion and drift of photogenerated carriers of the back-contact structure perovskite solar cell are calculated here detailly. Furthermore, the influence of carrier diffusion length, geometric scale, position of back-contact buried gate, and structure of the cell on performance is analyzed. The results showed that the PCE of a modified back-contact perovskite solar cell is superior to that of reported back-contact structure cell and traditional p-i-n structure cell under the same material parameters. It shows that the modified back-contact perovskite solar cell with optimized parameters achieved PCE of 28.27 %.
