ABSTRACT = {This study introduces a novel approach to enhancing the performance of CdTe/IGZO-based 
heterojunction solar cells by utilizing IGZO as both a window layer and an electron transport 
layer (ETL). A comprehensive simulation using SCAPS-1D was conducted to evaluate the 
impact of various transparent conductive oxides (TCOs), including ITO, SnO<sub>₂</sub>, ZnO, and FTO, 
on key photovoltaic parameters such as power conversion efficiency (PCE), open-circuit voltage 
(Voc), short-circuit current density (Jsc), and fill factor (FF). The research also explores the 
critical role of transport layers (HTL/ETL) and their material properties, band alignment, carrier 
mobility, and defect density, in optimizing device performance. The study's key contribution lies 
in identifying ITO as the most effective TCO due to its superior electron mobility, while 
highlighting the trade-offs associated with SnO<sub>₂</sub> and ZnO, which exhibit enhanced optical 
properties but comparatively moderate performance. Furthermore, FTO is shown to yield the 
poorest results, underscoring the significance of TCO selection in thin-film solar cell design. By 
offering a detailed comparative analysis and optimization insights, this work provides a strategic 
pathway for developing high-efficiency, cost-effective CdTe/IGZO-based solar cells, advancing 
next-generation thin-film photovoltaic technologies. },
