High efficiency, highly flexible organic photovoltaic (OPV) cells are fabricated on amorphous zinc indium tin oxide (ZITO) substrate in replacement of commonly used polycrystalline indium tin oxide (ITO). Amorphous ZITO films are deposited on Arylite™ substrate via pulsed laser deposition (PLD) at room temperature. Excellent optical transmittance for visible spectrum is achieved. The ZITO films demonstrate a resistivity of ~20Ω/sq, comparable to the commercially available ITO films. Only small degradation in conductivity is observed after controlled bending test. Using a novel high efficiency bithiophene imide (BTI) polymer, the resulting pristine OPV devices demonstrate more than 7% power conversion efficiency (PCE), similar to devices using commercially available ITO on glass as substrate. Furthermore, good device PCE is maintained after repeated bending test.
