Abstract

Herein, we show that surface treatment of PEDOT:PSS films using propionic acid (PA) results in better device performance for the resulting CH₃NH₃PbI₃ perovskite solar cells (PCE > 15%). N₂ blow spreading of PA appears critical in enhanced performance. This weak acid treatment leads to no worse roughness, while providing larger perovskite grains.
