Abstract

Organic-inorganic metal halide perovskites have drawn the interest of scientific community due to their suitable optoelectronic properties and high solar cell efficiency. In this report, we demonstrated, for the first time, the application of Cs2CO3 - doped TiO2 as an efficient electron-transporting...
