title: Metal electrode-free perovskite solar cells with transfer-laminated conducting polymer electrode.
abstract: We report perovskite solar cells with a new device structure that employ highly conductive polymer poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (
  PSS) as the top electrode replacing commonly used metal electrodes. The
  PSS top electrode is prepared from its aqueous solution through a transfer-lamination technique rather than direct spin-coating, which converts the CH(3)NH(3)PbI(3) into PbI(2). Perovskite solar cells with the structure of glass/FTO/c-TiO(2)/m-TiO(2)/CH(3)NH(3)PbI(3)/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.
