Posting upcoming events, volunteer opts & moreMay 11, 2021 · In this study, PTAA was deposited at first and then LAD was deposited from the solution using orthogonal solvent with respect to the PTAA. The optimal PSCs processed by INDD method exhibited a high PCE of 20.32% that 93% of it still retained up to 1500 h in ambient condition without any encapsulation, indicating outstanding long-term stability. I was an Assistant Principal for five years before teaching ELAR for PTAA/Greenville last year. I graduated from University of North Texas in 2004 and I received my Masters in Education from Texas A&M University-Commerce in 2011. I am happy to be the Assistant Principal for PTAA/Greenville for the 2020-2021 school year. In particular, introduction of 1F‐PTAA polymer in (FAPbI3)0.85(MAPbBr3)0.15‐based mesoporous n‐i‐p structure PSCs achieves the high stabilized PCE of 21.2% at the maximum power point with improved Voc of 1.14 V.
