In this study, we have performed the numerical simulation on inverted planar structure perovskite solar cell based on NiO as a hole transport material (HTM) by SCAPS -1 D. Here we investigated the effects of defect density and energy level of the perovskite absorber layer and perovskite/HTM interface layer on the performance, respectively. The analysis revealed that values of J sc , V oc , and FF of perovskite solar cells are significantly reduced with increasing the defect density of perovskite layer. The power conversion efficiency severely reduced from 25 to 5% when the defect density increased from 10 13 to 10 18 cm ?3 , respectively. A similar trend was also found in case of interfacial defect between Perovskite and HTM layer. It was found that the defect energy level more than 0.3 eV above conduction band of perovskite has almost no detrimental effect on the device's efficiency. � 2019 Elsevier GmbH Final 2023-05-29T07:26:17Z 2023-05-29T07:26:17Z 2019 Article 10.1016/j.ijleo.2018.12.163 2-s2.0-85063291071 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85063291071&doi=10.1016%2fj.ijleo.2018.12.163&partnerID=40&md5=f23f4f3dfb8d18ac8cabb225bad713ba https://irepository.uniten.edu.my/handle/123456789/24726 182 1204 1210 Elsevier GmbH Scopus |
