ABSTRACT = {Cadmium sulfide (CdS) thin films are extensively utilized as a window layer in photovoltaic 
(PV) devices due to their high transmittance, suitable bandgap, and favorable electrical 
properties. This work presents a comprehensive performance analysis of CdS based thin 
films in PV applications, examining key factors such as optical, electrical, and structural 
properties. The bandgap (approximately 2.42 eV) allows effective photon transmission, 
reducing energy losses. Critical performance metrics, including film thickness, grain size, 
crystallinity, and interface quality with the absorber layer, are optimized to enhance charge 
separation and minimize recombination losses. The study highlights the balance between 
thin-film transparency and thickness to maximize photon absorption while ensuring film 
durability and stability in environmental conditions. The findings underscore the potential 
of CdS thin films to improve PV cell efficiency, offering insights into achieving higher fill 
factor (FF), short-circuit current (Jsc) and open-circuit voltage (Voc) in CdS-based PV 
devices.},
