Abstract This study focuses on the architecture modification of solution-processed methylammonium lead iodide ((CH3NH3)PbI3)-based planar perovskite solar cells. The modification is obtained through a facile and cheap step formation at low temperature (<100 °C) using a simple inexpensive spin-coating technique. (CH3NH3)PbI3, as a light harvesting layer, was sandwiched between zinc oxide nanoparticle (ZnO-NP) thin film […]
