Towards a promising systematic approach to the synthesis of CZTS solar cells

Abstract

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.

“…Among renewable energy technologies, which include geothermal, wind power, and biomass conversion, solar photovoltaics, converting sun light into electricity, carries the most potential, due to the continuous access to the infinite solar resource. Solar cells use the photovoltaic effect to convert solar energy into electricity and have been under development during the last few decades, toward improving their power conversion efficiency (PCE), reducing the cost of production, and satisfying environmental requirements, including sustainability of the fabrication materials and processes [1][2][3][4][5][6][7]. To date, solar cell development and conceptualization has evolved through three generations.…”
