Abstract

Highly efficient p-i-n perovskite solar cells employing a flat and thick CH ₃ NH ₃ PbI ₃ film and a thin PCBM film are fabricated by the solution-process at low temperature. Through attainment of optimized PCBM thickness and insertion of the LiF interlayer, the unit cell shows 14.1% of overall power conversion efficiency (PCE) with a J _sc of 20.7 mA cm ^-2 , a V _oc of 0.866 V, and a FF of 78.3% under AM 1.5G 100 mW cm ^-2 conditions, while a larger area 10 cell serially connected module (10 × 10 cm ² ) shows an 8.7% PCE. These PCE values are the highest reported to date for the planar perovskite-PCBM solar cells. This journal is
