“…Regarding optoelectronic properties, PEA perovskites exhibit intriguing behaviours such as tunable band gaps, strong light-matter interactions, and enhanced stability compared to their 3D counterparts. [21][22][23][24] This organic-inorganic hybrid nature enables them to serve as promising candidates for various optoelectronic applications. 25,26 Additionally, PEA lead halide perovskites demonstrate improved stability compared to purely inorganic perovskite counterparts, attributed to the mitigating effects of organic cations on defects and structural instabilities.…”
