Lee, Hyun-Jung published the artcilePerformance improvement of slot-die-deposition based perovskite solar cells using diglycolic acid additives, COA of Formula: C4H6O5, the main research area is diglycolic acid slot die deposition perovskite solar cell.
In slot-die-coating process, novel approaches for better perovskite film formation were continuously required. Here, we studied additive processes for better slot-die-processed perovskite fabrication. As a novel additive, we introduced diglycolic acid (DA) material having a carboxyl group, well known as an effective functional group. With adding optimal amount of DA in the perovskite precursor solution, device efficiency and stability were all improved; DA-based perovskite device showed the best PCE of 14.63%. Moreover, the DA-based devices showed superior long-term stability guaranteeing 80% of initial efficiency during 95 days.
