We report perovskite solar cells with a new device structure that employ highly conductive polymer poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT:PSS) as the top electrode replacing commonly used metal electrodes. The PEDOT: PSS top electrode is prepared from its aqueous solution through a transfer-lamination technique rather than direct spin-coating, which converts the CH3NH3PbI3 into PbI2. Perovskite solar cells with the structure of glass/FTO/c-TiO2/m-TiO2/CH3NH3PbI3/spiro-OMeTAD/PEDOT: PSS yield a maximum open-circuit voltage (V-OC) of 1.02 V, and a maximum power conversion efficiency (PCE) of 11.29% under AM1.5 100 mW/cm(2) illumination. The whole device was fabricated in air without high-vacuum deposition which simplifies the processing and lowers the threshold of both scientific research and industrial production of perovskite solar cells.
