Inverted (p-i-n) perovskite solar cells using a low temperature processed TiO _x interlayer.

ABSTRACT: In this article, we present the improvement in device performance and stability as well as reduction in hysteresis of inverted mixed-cation-mixed-halide perovskite solar cells (PSCs) using a low temperature, solution processed titanium oxide (TiO _x ) interlayer between [6,6]-phenyl-C₆₁ butyric acid methyl ester (PCBM) and an Al electrode. Upon applying a TiO _x interlayer, device resistance was reduced compared to that of the control devices, which results in improved rectification of the characteristic current density-voltage (J-V) curve and improved overall performance of the device. PSCs with the TiO _x interlayer show an open-circuit voltage (V _oc) of around 1.1 V, current density (J <
