Abstract
This study introduces the development of a novel$\text{Cd}_{\mathrm{x}} \text{Te}_{\mathrm{y}} \mathrm{O}_{z} / \text{CdS} /$por-$\text{ZnO} / \text{ZnO}$heterostructure synthesized through an economically efficient and straightforward method for use in portable solar cells. Employing the Successive Ionic Layer Adsorption and Reaction (SILAR) method in conjunction with atmospheric air annealing, we have successfully fabricated a multilayer structure without requiring expensive equipment or vacuum processes. The simplicity of the manufacturing process, combined with the heterostructure's promising optical and electronic properties, indicates its viability in the application of portable solar cells. This research not only advances the field of photovoltaic materials but also paves the way for further optimization and exploration of cost-effective solar energy solutions.
