Enhanced stability and optical performance of MAPbI3 perovskite films through B4PBF4 ionic liquid integration: A route to durable photovoltaics

An ionic liquid (B4PBF4) was synthesized and characterized using spectroscopic techniques, incorporating it in different proportions (0.25, 0.5, and 1.5 % w/w) into thin perovskite films. The results show that 1.5 % concentration significantly improves the optical properties by minimizing trap state...

description An ionic liquid (B4PBF4) was synthesized and characterized using spectroscopic techniques, incorporating it in different proportions (0.25, 0.5, and 1.5 % w/w) into thin perovskite films. The results show that 1.5 % concentration significantly improves the optical properties by minimizing trap states and preventing charge recombination. XPS analysis indicates a strong interaction between the ionic liquid and lead halides at this proportion. Additionally, photovoltaic devices fabricated with this percentage achieved higher efficiency. In terms of stability, the 1.5 % also prevented water absorption on the surface, delaying film degradation up to 500 h.
