Next-generation nanotechnology: Exploring the potential of In2S3-based perovskite solar cells

Abstract

A potential technology for converting clean and renewable energy is perovskite solar cells (PSCs). The electron transport layer (ETL), one of the vital parts of PSCs, is essential for improving device stability and efficiency. The relevance of indium sulfide (In2S3) as a superior material for ETL in PSCs is explored in this article. We analyzed the operation of PSCs and emphasized the value of ETLs in enabling effective charge extraction and minimizing recombination losses. In2S3 is a favorable nanomaterial for ETL applications due to its advantageous bandgap, excellent electron mobility, and chemical stability. Furthermore, the perovskite layer is shielded by In2S3's passivation properties, which also increase the stability of the device. A summary of recent developments in In2S3-based ETL research, including material engineering and deposition methods improvements, has been provided. The main view for the future is the possibility of improved In2S3 property optimization and interface engineering to improve PSC performance. Collaboration between scientists working on solar energy, devices, and materials will probably lead to new discoveries and test the limits of In2S3-based ETLs. Novel hybrid architectures and tandem arrangements provide exciting opportunities for better charge extraction with existing electron transport materials. The current investigation of In2S3-based ETLs in PSCs offers significant promise to revolutionize the solar energy sector, opening the path for sustainable and effective photovoltaic technology. However, stability, toxicity, and large-scale production issues must be addressed.
