Abstract

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:;<=6/5>?21: 5AA/BC and 012/5>?21: 5AA/56789:;<=6/412/BC. Theachieved power conversion efficiencies were 13.94% and 10.99%, for n-i-p and p-i-n PSCs, respectively. In order to enhance its performance, several materials were suggested as electron and hole transport layers (ETL and HTL). For both configurations, it was found that Zinc oxide (NO2) and titanium dioxide (1<2P) are the most adequate materials as ETL and Copper (I) thiocyanate (RCARS) forms the appropriate HTL. Also, 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:;<=6/1<2P interface on our PSCs performance is also presented. Furthermore, the effect of temperature on PSCs were studied.
