“…Among the used BSF layers, Cu 2 O has attracted considerable attention from the scientific community due to its excellent photovoltaic properties, suitable bandgap of 2.2 eV, non-toxic nature, high absorption coefficient, and intrinsic p-type conductivity [23,24]. Moreover, it can be deposited using simple and low-cost techniques of fabrication [25,26].…”

One of the major limitations causing deadlock in solar cells with higher sulfur content in the photovoltaic absorber material is the unintended formation of an uncontrollable MoS2 layer between the absorber material and Mo back contact, which can affect negatively the efficiency of solar cells. Researchers reported that it is very difficult to control the MoS2 properties such as the conductivity type, thickness, band gap, and carrier concentration in experiments. Considering these challenges, an initial step involved a thorough examination utilizing the one-dimensional solar cell capacitance simulator (SCAPS-1D) to assess the impact of n-MoS2 interlayer thickness and donor concentration on the performance of CMTS solar cells. Our investigation revealed the formation of a “cliff-like CBO” at the CMTS/n-MoS2 interface, facilitating the transport of electrons from the p-CMTS absorber to the Mo back contact, resulting in a significantly higher recombination rate. Subsequently, herein a novel approach is proposed, using Cu2O as a back surface field (BSF) layer due to its low cost, intrinsic p-type properties, and non-toxic nature. Simulation results of a novel heterostructure (Mo/Cu2O/CMTS/CdS/i-ZnO/AZO/Al) of the CMTS-based solar cell are discussed in terms of recombination rate and conduction band alignment at the absorber/BSF interface. A desired “spike-like CBO” is formed between CMTS/Cu2O, which hinders the transport of electrons to the back contact. By optimizing the physical parameters such as thickness and the doping density of the Cu2O layer, an efficiency η of 21.78% is achieved, with an open circuit voltage (Voc) of 1.26 V, short-circuit current density (Jsc) of 24.45 mA/cm², and fill factor (FF) of 70.85%. Our simulation results offer a promising research direction to further develop highly efficient and low-cost CMTS solar cells.

The large tree species Terminalia catappa is a member of the Combretaceae family and is mainly found in tropical climates. They are commonly cultivated for shade because they have huge, dense foliage. Numerous polyphenols, including flavonoids, tannins, saponins, and phytosterols, are present in the leaves. In this study, the green chemical method was used to extract polyphenols from dried green almond leaves. They were employed in the synthesis of Cu2O nanoparticles as a reducing agent. FTIR and UV–Vis were used to describe the leaf extract of Terminalia catappa after the chlorophyll was removed. Copper salt was used to create Cu2O nanoparticles via a reduction process. The extract's potential for photocatalytic dye degradation has also been explored. The obtained Cu2O had a spherical shape with dimensions of 50–100 nm, and its band gap energy reached 1.945 eV to remove methylene blue from aqueous media under visible light irradiation conditions. At an initial MB concentration of 10 ppm, the decomposition efficiency reached 71.99% after only 2 h of exposure to simulated sunlight. The decomposition process occurred according to a pseudo-first-order kinetic model with a rate constant of 0.0084 min−1.
