The influence of service failures on customer emotions in the South African banking industry

Abstract : This paper reported numerical simulation and performance improvement of nanostructured Cu2O/TiO2 pn heterojunction solar cells. The solar cells equations were modelled and thereafter theoretical validation of the nanostructured metal oxides was performed. The model working points include a room temperature of 300K, input power of 1000W/m2 using an illumination of AM1.5 lamp, and thickness of 2 μm. The modelled solar cell exhibits a short-circuit current (Jsc) of 0.2819 A, the open-circuit voltage (Voc) of 0.1640 V, the fill factor (FF) of 0.28, and the efficiency (η) of 13.38% at 2.00 μm thickness. Also, the band gap, electron affinity and Nyquist plot were obtained for the solar cells. This will serve as a theoretical guide for laboratory research on the improvement of efficiency of Cu2O metal oxide solar cells. This will open a new frontier for modelling of metal oxide based thin films solar cells especially Cu2O thin films solar cells. This is boaster in the quest to develop affordable and sustainable energy by encouraging more research in solar cells technologies in low-income countries
