Used in the fabrication of perovskite-based optoelectronic devices, particularly light-emitting diodes (LEDs) and solar cells. The compound helps stabilize the perovskite structure, improving device efficiency and reducing phase impurities. It is especially effective in enhancing the performance of quasi-2D perovskites by passivating defects at grain boundaries and suppressing non-radiative recombination. Its application leads to brighter emission in LEDs and higher open-circuit voltage in photovoltaic cells. Also explored in radiation detection due to favorable charge transport properties.
