Passivation of Perovskite Films Using Ionic Liquids

Alashkar, Adnan / Ibrahim, Taleb / Khamis, Mustafa / Hai Alami, Abdul

In this paper, the carrier recombination, and dynamics of Perovskite Solar Cells (PSC) are investigated. Ionic Liquids (IL) are presented in the bulk perovskite in an attempt to improve the dynamics of the charge transport layer. Time Resolved Photoluminescence (TRPL) is utilized to study the fast electronic decay of the perovskite samples and the influence of the IL on the stability of the perovskite film. The ILs are added to the perovskite in three ratios (5%, 10%, and 20%). The results showed that the presence of the ILs increases the electron lifetime inside the perovskite layer. In addition, 10% IL/perovskite displayed the highest increase of 72% in the lifetime. Where, for higher ratios, the lifetime started deteriorating.
