| Popis: | This work is a numerical simulation of a hetero-junction solar cell (HJSC) based on cuprous oxide (Cu2O) as an absorber p-layer and aluminium doped zinc oxide (AZO) as a window layer. In addition, on the basis of real experimental structures, three different materials were considered for the buffer layer between AZO and Cu2O. Using ZnO first, AGO and then ZGeO as the buffer layer, the efficiency of the solar cell has increased remarkably from 4.26 to 8.72% in a good agreement with the measured values (4.13–8.23%). This achieved agreement is due to the fact that the right parameters were chosen. We have also studied the effect of the band gap and the electron affinity of the buffer layer and that of the front window to optimize the structure with the ZGeO buffer layer. The optimized HJSC has achieved a remarkable conversion efficiency of 11.30% with Voc = 1.28 V, Jsc = 10.82 mA/cm2 and FF = 0.81. |
