Abstract

In this review article, we explore the insertion possibility of molybdenum disulfide (MoS2) thin-film heterostructures into copper, zinc, and tin sulfide (CZTS) based thin film solar cells for improved performance. CZTS has gained prominence as a naturally occurring, non-toxic alternative to conventional solar energy system materials, necessitating a focus on the study of integrating MoS2 (as a back contact) with thin-film solar cells with CZTS integration, as well as understanding the impact on device efficiency and stability to advance, upscale, and commercialize products. By analyzing the MoS2-CZTS interface, critical insights into MoS2's functioning in optimizing charge carrier dynamics, lowering recombination losses, and enhancing overall device performance have been framed in this work. Furthermore, the necessity of optimizing process parameters and characterizing MoS2 back contacts in the context of CZTS-based solar cells is discussed. This thorough study intends to highlight the revolutionary potentials of MoS2 back contact structures, pave the way for future developments in optoelectronics, and contribute to the continued-evolution of sustainable energy technology. This article will be a valued resource for understanding and coupling the synergies between MoS2 back surface field (BSF) and CZTS in thin film solar cell applications for future advancement.
