Deposition and Characterization of Molybdenum Disulfide (MoS2) on FTO/Glass Substrates for High Performance HJT Solar Cell

Abstract:

In recent year, 2D layered materials, such as molybdenum disulfide (MoS2), have attracted strong interest in developing high-performance heterojunction solar cell, due to their desirable optical and electrical properties [1,2]. It has been reported that MoS2 exhibits one order of magnitude higher sun light absorption than Si and GaAs [3]. These solar cells have demonstrated power conversion efficiencies (PCEs) of up to a few percent in just a few nanometer-thick layers [4].
In this work it is presented the deposition of MoS₂ on fluorine-doped tin oxide (FTO) via drop casting as a novel approach for heterojunction fabrication in photovoltaic cell applications. This technique allows for maintaining low processing temperatures, which is crucial for the stability of the underlying layers. The MoS₂/FTO configuration aims to enhance the efficiency of solar cells by leveraging MoS₂’s unique optoelectronic properties. The work focuses on innovative materials and structures to optimize photovoltaic performance while maintaining cost-effectiveness. The findings contribute to advancing sustainable energy technologies through the development of advanced cell architectures.
