“…The presence of the sub-bandgap associated with Cr-substituted CGST films may result in an enhanced current generation at the voltage corresponding to the energy gap value, as explained in the simulation section. [3,19,51,52] The determination of the optical bandgap for the thin films involves extrapolating the linear segment of the graph to the photon energy (hν) axis, using Tauc's equation. [5] As depicted in Figure 3, the application of Tauc's method reveals that the bandgap for the pure CGST film equals 2.40 eV.…”

Designing effective strategies for mitigating energy crisis highlights a research gap in current solar cell technologies. This study explores the inherent physicochemical properties of thin films composed of copper gallium sulfide telluride (CuGa1−xCrx(S,Te)2) with chromium substitution, prepared through the chemical spray pyrolysis technique. The investigation showcases how the concept of intermediate band structuring contributes to enhancing solar cell efficiency. This enhancement can be attributed to the remarkable mobility (from 1.80 to 5.48 cm2 V−1 s−1) and conductivity (from 1.00 to 6.06 S cm−1) exhibited by pure and 0.1 chromium thin films, respectively. Notably, the Cr‐0.1‐substituted CGST film displays maximum photoresponsivity of 0.624 AW−1, an external quantum efficiency of 145%, and a detectivity of 2.37E10. The fabricated solar cell is subjected to theoretical simulation using solar cell capacitance simulator‐1D software, revealing an upward trend in efficiency from 7.13% to 11.23% with increasing Cr substitution from 0.025 to 0.1. This efficiency improvement can be ascribed to the reduction in bandgap (from 2.40 to 1.72 eV) and the creation of a sub‐band in CGST due to Cr incorporation, as substantiated by UV–vis and NIR spectroscopy. These outcomes suggest that Cr‐0.1‐substituted CGST holds promise as a potential thin film absorber material in solar photovoltaics.

“…Rod-like Ag 2 S nanocrystals of the size between 200 and 400 nm were synthesized using precursor sodium thiosulfate [44]. More recently, the coprecipitation method has been used to prepare Ag 2 S-chitosan composite, and investigation is made on the effect of chitosan on the morphological and optical properties of Ag 2 S. The potential of as prepared composite was demonstrated for photocatalytic applications [45]. Singh et al developed Ag 2 S inside titanium dioxide with the average particle size of 19 nm for photocatalytic hydrogen-generation application [46].…”

Silver sulfide nanoparticles belong to the family of important metal chalcogenides. Silver sulfide has been extensively studied in recent years due to its applications in various fields ranging from biosensors, infrared detectors, and optoelectronics to catalysis. Silver sulfide is considered as a potential photocatalyst due to narrow band gap energy, mechanical and thermal stability, cyclability, and ease of synthesis. Different methods have been investigated to produce various forms of silver sulfide nanoparticles. The present chapter focuses on the recent progress in synthesis of silver sulfide nanoparticles using hydrothermal method, chemical bath deposition, microwave-based approach, sonochemical method, single molecular precursor’s decomposition, and green synthesis. Moreover, the application of silver sulfide nanoparticles in photocatalytic degradation of organic dyes is discussed in details.
