Abstract:The
electron transport layer (ETL) plays a critical role in efficient
and stable perovskite solar cells (PSCs). The current effective method
for the large-scale preparation of metal oxide ETLs is mainly based
on expensive sputtering processes. Here, a screen-assisted self-spreading
method is proposed as a novel approach to prepare uniformly thin and
conformal TiO2 films on a rough fluorine-doped tin oxide
(FTO) substrate as an ETL in planar PSCs. The TiO2 ETL
deposited by this method exhibited good coverage an… Show more
