Enhanced performance of mesostructured perovskite solar cells in ambient conditions with a composite TiO^sub 2^–In^sub 2^O^sub 3^ electron transport layer

Perovskite solar cells (PSCs) with a composite mesoporous TiO2 -In2 O3 electron transport layer were constructed and tested. For the formation of the In2 O3 overlayer three different molar concentrations of the precursor indium(III) acetylacetonate were investigated (TiO2 -In2 O3 (1) 46 mM, TiO2 -In...
