Transition metal dichalcogenides solar cells and integration with perovskites
Nano Energy(2023)
摘要
Two-dimensional (2D) layered semiconductors have emerged as promising materials for state-of-the-art photo-voltaic devices (PV) due to their unique optoelectronic properties. The 2D materials have the potential to develop highly efficient solar cells because of their high transparency, large charge carrier mobility, and, in particular, tunable electronic structures. The development of PVs using mechanical exfoliation and chemical vapor depo-sition enables the utilization of intrinsic semiconductors such as 2D transition metal dichalcogenides (TMD). In this focused review, we summarize the recent progress and advanced strategies adopted for developing efficient and stable solar cells using 2D TMD materials. The review systematically discusses the crucial impacts of TMDs on the performance of PVs alongside their integration with perovskite solar cells for stability improvement. It also addresses the synergetic role of TMDs as metal interfaces and transparent conducting electrodes for PV applications. Finally, it concludes with a comparison of the performance and characteristics of 2D solar cell devices, as well as a discussion of current challenges and potential solutions.
