Another material, MoTe2, which acts as a hole transport layer (HTL) is also preferred for solar cells design. MoTe2 HTL provides an addition back surface field that increases the collection of holes at back contact, thus facilitating generation of photonic energy. The presented research involves an in-silico examination of their tandem effect in solar energy generation, using the simulation software SCAPS-1D. Results reveal that in the MoTe2 HTL solar cells having 2500 nm thickness of CuSbS2 absorber layer, the maximum power conversion efficiency achieved was 30.4%, at a bandgap of 1.4 eV. The effects of energy bandgap and thickness of CuSbS2 absorber layer on performance parameters of solar cells containing short-circuit current (Jsc), open-circuit voltage (Voc), and fill factor (FF) were als...
