Abstract

Abstract : In article number1803872, Aleksandra B. Djurišić, Zhubing He and co‐workers report a promising inverted planar perovskite solar cell using NiO as the hole‐transport‐layer. Significant suppression of interfacial recombination is achieved by a facile alkali chloride modification at the interface between NiO and perovskite. This modification induces the ordering of the perovskite crystal and in turn decreases its defect/trap density, hence reducing interfacial recombination and augmenting the device open‐circuit voltage significantly.
