Role of Antisolvent Temperature and Quaternary Ammonium Cation-based Ionic Liquid Engineering on the Performance of Perovskite Solar Cell Processed Under Air Ambient Conditions Interestingly, the optimized devices showed high stability and retained over 90% efficiency after 1500 hr of dark storage with a periodic measurement under ambient conditions. The combined effect of low-temperature chlorobenzene antisolvent (5 ☌) and 0.01 M resulted in an enhancement of over 16% as compared to pristine devices. A quaternary ammonium cation based ionic liquid, trimethylpropylammonium bis(trifluoromethanesulfonyl)imide, is applied at the TiO2/perovskite interface to passivate the interfacial defects and improve the electron transfer efficiency. Chlorobenzene antisolvent of low-temperature produces compact perovskite films and better interfacial contact.
Herein, a combination of antisolvent and ionic liquid engineering is applied to produce efficient and stable perovskite solar cells under ambient conditions. However, to make the technology available in the market and commercially successful, efficient and stable perovskite solar cells must be fabricated under ambient conditions. Perovskite solar cells are becoming one of the strong contenders for renewable energy generation sources.
