High-Oriented SnO2 Nanocrystals for Air-Processed Flexible Perovskite Solar Cells with an Efficiency of 23.87
{{output}}
Tin (IV) oxide (SnO2) electron transport layer (ETL) emerges as the most promising n-type semiconductor material for flexible perovskite solar cells (f-PSCs). The (110) facet-dominated SnO2 colloids are readily created, whereas other best-performing (101) and ... ...
