“…Figure 7 b illustrates the slight displacement of CdS-doped Ag from their pre-doping positions, at 2θ = 27.84°, oriented along the (002) (JCPDS-00-041-1049). Changes in peak position and FWHM suggest that Ag doping affects the microstructure, crystal quality, and lattice parameters 35 . Figure 7 c, showed that the strong peak a little bit shifting positioned at 2θ = 26.94°, is oriented along with the (111) and (002), directions and is in good agreement with the (JCPDS-01-075-0581) and (JCPDS-01-080-0006), suggesting both cubic and hexagonal form.…”

This study aims to enhance the CZTS device's overall efficiency, the key research area has been identified in this study is to explore the effects of a novel, low-cost, and simplified, deposition method to improve the optoelectronic properties of the buffer layer in the fabrication of CZTS thin film solar cells. Herein, an effective way of addressing this challenge is through adjusting the absorbers' structure by the concept of doping, sensitized CdS thin film by the bi-functional linker, and an environmentally friendly catalytic green agent. The Linker Assisted and Chemical Bath Deposition (LA-CBD) method was introduced as an innovative and effective hybrid sensitization approach. In the one-step synthesis process, Salvia dye, Ag, and 3-Mercaptopropionic acid (MPA) were used. Generally, the results for all samples displayed varying bandgap as achieved between (2.21–2.46) eV, hexagonal structure with considerably decreased strain level, broader grain size, and dramatically enhanced crystalline property. Hence, the rudimentary CdS/CZTS solar cell devices were fabricated for the application of these novel CdS films. Preliminary CZTS thin film solar cell fabrication results in the highest conversion efficiency of 0.266% obtained CdS + Salvia dye, indicating the potential use of the CdS films as a buffer layer for CZTS photovoltaic devices.
