Inorganic electron transport layers (ETLs), such as titanium dioxide (TiO2) and tin (SnO2), are important in n–i–p structured perovskite solar cells (PSCs). In particular, the ETLs for flexible PSCs (f-PSCs) using a polymer substrate require strong adhesion with transparent conducting oxide (TCO) formation of uniform thin film at temperature below 150 °C. Hence, SnO2 colloidal nanoparticles primarily used to meet these demands. Nevertheless, there exist further opportunities improvement terms efficiency, coating, on TCO. this study, we prepared SnO2–TiO2 hybrid electrode by adding certain amount TiO2 nanosol, which functions an inorganic binder, solution. comparison colloid alone, f-PSC fabricated demonstrated not only better mechanical reliability against bending due but also greatly improved efficiency because energy alignment. Eventually, resulted 21.02% even over 16% mini-module (7 × 7 cm2) coating large area. This study provides new strategy ETL high-efficiency f-PSCs.
