Highly efficient and air‐stable inverted polymer solar cells are fabricated with a poly(2,7‐carbazole) derivative (PCDTBT):fullerene derivative (PC 70 BM) active layer. Low‐temperature‐annealed sol‐gel‐derived zinc oxide (ZnO) and molybdenum oxide films are selected as the electron and hole transporting layers, respectively. Power conversion efficiency (PCE) of 6.3% is demonstrated, which is the highest reported to date for inverted polymer solar cells.
