Enhanced Stability and Optical Performance of Mapbi₃ Perovskite Films Through B4pbf₄ Ionic Liquid Integration: A Route to Durable Photovoltaics

Published: Jan. 1, 2025

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