In this study, nickel-oxide (NiOX) thin-films are investigated as a potential HTL for PSCs. The NiOX films are prepared by electron-beam physical vapor deposition at low temperatures. The crystalline properties and the work function are determined by X-ray diffraction and photoelectric yield spectroscopy. The transmission and the complex refractive index of the films are determined by optical spectroscopy and ellipsometry. Furthermore, PSCs are fabricated and characterized. The short-circuit current density (Jsc) of the PSC is limited by the optical loss due to the NiOx front contact. The optical losses of the front contact are quantified by optical simulations using finite-difference time-domain simulations, and a solar cell structure with improved light incoupling is designed. Furthermore, the electrical characteristics of the solar cell are simulated by finite element method simulations. As a result, it is found that the optical losses can be reduced by 70%, and the light incoupling can be improved so that the JSC can be increased by up to 12%, allowing for the realization of PSCs with an energy conversion efficiency of 22%. Findings from the numerical simulations are compared with experimentally realized results. � 2020 Wiley-VCH GmbH Final 2023-05-29T08:07:46Z 2023-05-29T08:07:46Z 2020 Article 10.1002/smtd.202000454 2-s2.0-85089159401 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85089159401&doi=10.1002%2fsmtd.202000454&partnerID=40&md5=62bd3d1990f026b65205631e8c4950d8 https://irepository.uniten.edu.my/handle/123456789/25274 4 9 2000454 John Wiley and Sons Inc.
