Flexible polymer solar cells using high conductivility Ag∶Cu∶Ni metal grid anode

A new metal grid anode made of silver, copper and nickel is reported. Using it as anode, P3HT(poly(3-hexylthiophene)): PCBM(［6,6］-phenylC61butyricacidmeth-ylester) layer as active layer，flexible polymer solar cells were manufactured by spin-coating. Five different structures of solar cell devices were made by using the traditional Indium tin oxide（ITO）anode material or the new anode material. After comparison, it is found that the performances of the new anode material device is greatly improved, open circuit voltage of 0.54V, short circuit current density of 5.39mA/cm2, and power conversion efficiency (PCE) of 2.060% are achieved under 50mw/cm2 illumination.
