Résumé : 

In this article, we highlight a numerical investigation on n-AZO/p-Cu2O solar cell based Analysis of Microelectronic and Photonic Structures software. The natural p-type Cu2O materials distinguish by the medium bandgap energy, the low doping concentration of carriers and the high absorption coefficient (>104 1/cm). The n-type AZO (Al-doped ZnO) materials distinguish by the wide bandgap and the heavy doping concentration of carriers. Metal oxide heterojunction solar cells are being fabricated and used for alternating the failed metal oxide homojunction solar cells which had deeper energy conversion efficiency to the point of lack. The AZO/Cu2O structure promotes to design low cost solar cell devices. The investigated cell is an n-p heterojunction structure made of the two different metal oxide semiconductors: the window AZO layer and the absorber Cu2O layer. By varying the temperature, the open circuit voltage (VOC), the short circuit current (JSC), the fill factor (FF) and the efficiency of AZO/Cu2O solar cell were investigated and optimized.
