The performance parameters such as open circuit voltage (Voc), short circuit current density (Jsc), fill factor (FF), conversion efficiency (?), and quantum efficiency (QE) have been examined for cells with different carrier concentration and series resistance (Rs) of window layer materials. Calculation results shows that the incorporation of oxygen (CdS:O) with series resistance (Rs ? 1E?1 ?.cm2) and minimum carrier concentration of 1016 cm?3 contributes in optimum band alignment that enhances photo-current collection from both short and long wavelength regions compared to baseline CdS/CdTe solar cell. Moreover, the performance of the proposed cells has been improved in terms of QE, Jsc, Voc, ?, and FF upon insertion of novel CdZnS layer. However, carrier recombination increases the saturation current density for CdZnS resulting in unstable performance. Consequently, upon insertion of CdS:O window layer, conversion efficiency enhancement is observed with Jsc (29.10 mA.cm?2), Voc (0.889 V) and FF (70.39%). The proposed window materials are deposited using RF-sputtering method and the experimental results are incorporated in simulation to validate the findings. � 2022 International Solar Energy Society Final 2023-05-29T09:38:20Z 2023-05-29T09:38:20Z 2022 Article 10.1016/j.solener.2022.01.049 2-s2.0-85123759467 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85123759467&doi=10.1016%2fj.solener.2022.01.049&partnerID=40&md5=2abf66e41c5c6692ac7092af494f4960 https://irepository.uniten.edu.my/handle/123456789/26978 233 523 530 Elsevier Ltd Scopus |
