Used in the fabrication of perovskite-based optoelectronic devices, particularly light-emitting diodes (LEDs) and solar cells. It helps stabilize the perovskite structure and improves film quality by reducing defects and enhancing crystallinity. The compound is also employed in solution-processed thin-film technologies due to its favorable solubility and film-forming properties. Its role in phase control makes it valuable for tuning emission color in green to blue-emitting devices. Additionally, it contributes to improved device efficiency and operational stability in ambient conditions.
