| Résumé : |
In this work two perovskite solar cells in n-i-p and p-i-n configurations were studied using SCAPS simulator. The two primary solar cells’ structures are 012/412/ 56789:;?21: 5AA/BC and 012/5>?21: 5AA/56789:; it was found that Zinc oxide (NO2) and titanium dioxide (1 performances of n-i-p and p-i-n PSCs were improved by optimizing the absorber thickness which was found to be 1 UV. With these considerations the power conversion efficiency reached 25.02% and 25.11% for conventional (n-i-p) and inverted PSCs, respectively .In addition, the detrimental effect of defects at the Z6789:; interface on our PSCs performance is also presented. Furthermore, the effect of temperature on PSCs were studied. |
