Low-temperature processed SnO2 compact layer for efficient mesostructure perovskite solar cells
TL;DR: In this paper, a nanoparticle film has been synthesized via low-temperature solution-processing and proposed as compact layer in mesostructure perovskite-type solar cell (PSC), which brings perfect crystal-lattice and bandgap matching between electron selective layer and FTO substrate and close interface-contact between cl-SnO 2 and mesoporous TiO 2 layer (mp-TiO 2 ), which contributes to suppressing carrier recombination and optimizing device performance.
