Conversion efficiency for all band-gap energies of CIGS were calculated based on proposed new CIGS/WS2 structure. Numerical modelling tools were used to investigate the effects conduction band offset and interface defect state on the photovoltaic parameters of CIGS/WS2 solar cell. The model predicts the density of defect tolerance in the interface is 1 � 1011 cm3. Based on optimization, the highest efficiency of 26.4% has been achieved for CIGS/WS2 solar cell with Eg(CIGS) = 1.4 eV (Voc = 1.026 V, Jsc = 29.57 mA/cm2 and FF = 86.96%) which is better than that of CIGS (23.4%) solar cell. The simulation further identifies that proposed CIGS/WS2 structure is less temperature sensitive compared to conventional Si solar cell. This research paves the way for WS2 thin film as a potential window layer material for CIGS solar cells. � 2020 Final 2023-05-29T08:07:48Z 2023-05-29T08:07:48Z 2020 Article 10.1016/j.solener.2020.07.007 2-s2.0-85087666837 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85087666837&doi=10.1016%2fj.solener.2020.07.007&partnerID=40&md5=000e3fe28317325b6eddffdc76741ed9 https://irepository.uniten.edu.my/handle/123456789/25277 207 479 485 Elsevier Ltd Scopus |
