Used primarily in the fabrication of perovskite solar cells, this compound contributes to improved film quality and enhanced device stability. Its unique cation structure helps in forming a more uniform and defect-resistant perovskite layer, which increases power conversion efficiency. It is especially valuable in two-dimensional (2D) or quasi-2D perovskite configurations, where it acts as a spacer to improve moisture resistance and thermal stability. The material supports solution-based processing techniques, making it suitable for low-cost, large-area photovoltaic applications. Additionally, it has been explored in light-emitting diodes and photodetectors due to its favorable optoelectronic properties.
