A one-step low temperature processing route for organolead halide perovskite solar cells

Abstract

Organolead trihalide perovskite solar cells based upon the co-deposition of a combined Al2O3–perovskite layer at T < 110 °C are presented. We report an average PCE = 7.2% on a non-sintered Al2O3 scaffold in devices that have been manufactured from a perovskite precursor containing 5 wt% Al2O3 nanoparticles. © 2013 The Royal Society of Chemistry.
