Solution-Processed Cu2O and CuO as Hole Transport Materials for Efficient Perovskite Solar Cells.

Solution-processed Cu2 O and CuO are used as hole transport materials in perovskite solar cells. The cells show significantly enhanced open circuit voltage Voc, short-circuit current Jsc, and power conversion efficiency (PCE) compared with PEDOT cells. A PCE of 13.35% and good stability are achieved for Cu2O cells, making Cu2O a promising material for further application in perovskite solar cells.
