A photovoltaic cell of CuPc:P3HT:PCBM was introduced to extend the light absorption in the visible wavelength between 300~500 and 550~800 nm. By fabricating the photovoltaic cells of ITO / PEDOT:PSS / CuPc:P3HT:PCBM / BCP / Al with smallmolecular and polymer donating materials blended layer, we demonstrated a high PCE of 4.20% with high Jsc of 10.05 mA/cm². This performance of photovoltaic cell with the blended layer of small-molecular and polymer can be competitive with that of tandem cells.
