“…Furthermore, variations in acceptor density might impact carrier transport characteristics, hence impacting the efficiency of solar cells. Additionally, high acceptor density may introduce defects in the material, which also influencing the overall cell performance [46,47]. Conversely, a high defect density may cause the absorber layer's carrier recombination to rise.…”

Ultra-thin flexible photovoltaic materials for solar cells, like transition metal di-chalcogenides (TMDCs), hold significant promise due to their advantageous properties in photon absorption and electronic transport, being composed of atomically thin 2D layered semiconductor materials. An essential 2D-layered substance, tungsten Disulfide (WS2), classified as a TMDC, has garnered substantial attention due to its notable chemical and physical characteristics. This work presents a novel method for getting good photovoltaic results using WS2 solar cells. The suggested configuration "Al/FTO/SnS2/WS2/CuO/Ni" comprises two absorber layers, which involves incorporating CuO as a supplementary absorber layer and SnS2 as the buffer layer. Several metals with varying work functions were investigated one at a time, therefore, Al and Ni were chosen for the front as well as back contact in order to produce a low resistance metal-semiconductor (M-S) interface. Additionally, aluminum (Al) and nickel (Ni), are commonly used due to their well-understood properties such as conductivity and thermal stability. Subsequently, an analysis was conducted to determine the effects of important influencing factors, such as operating temperature, layer thickness, defects density, and doping density of the absorber and buffer layers. The power conversion efficiency (PCE) was achieved approximately 30%, accompanied by an open circuit voltage (VOC) of 1.02 V, a short circuit current (JSC) of 34.35 mA/cm2, and a fill factor (FF) of 87.27%. This improvement was achieved by utilizing an Al/FTO/SnS2/WS2/CuO/Ni heterostructure. In comparison, the reference cell without CuO (single absorber) had a PCE of 21.74%, VOC of 0.88 V, JSC of 28.6 mA/cm2, and FF of 86.23%. The results obtained from an extensive numerical analysis and demonstrate the immense potential of the SnS2/WS2/CuO heterostructure, indicating a promising direction for the manufacturing of photovoltaic and photonic devices based on WS2-TMDCs. This study provides a systematic roadmap for the fabrication process as well as realization of low-cost high efficiency solar cell.

This study introduces an innovative method for synthesizing Cadmium Oxide /Cadmium Sulfide/Zinc Oxide heterostructures (CdO/CdS/ZnO), emphasizing their potential application in solar energy. Utilizing a combination of electrochemical deposition and oxygen annealing, the research provides a thorough analysis of the heterostructures through scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) spectroscopy, X-ray diffraction (XRD), Raman spectroscopy, and photoluminescence (PL) spectroscopy. The findings reveal a complex surface morphology and a composite structure with significant contributions from hexagonal CdS and cubic CdO phases. The study highlights the uniformity in the distribution of luminescent centers and the crystalline quality of the heterostructures, which is evident from the PL analysis. The redshift observed in the emission peak and the additional peaks in the excitation spectrum indicate intricate optical properties influenced by various factors, including quantum confinement and lattice strain. The research demonstrates these heterostructures’ potential in enhancing solar cells’ efficiency and applicability in optoelectronic devices. This comprehensive characterization and analysis pave the way for future optimization and application in efficient and sustainable solar energy solutions.
