    Abstract
    A simple lamination process of the top electrode for perovskite solar cells is demonstrated. The laminate electrode consists of a transparent and conductive plastic/metal mesh substrate, coated with an adhesive mixture of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate), PEDOT:PSS, and sorbitol. The laminate electrode showed a high degree of transparency of 85%. Best cell performance was achieved for laminate electrodes prepared with a sorbitol concentration of similar to 30 wt% per milliliter PEDOT:PSS dispersion, and using a pre-annealing temperature of 120 degrees C for 10 min before lamination. Thereby, perovskite solar cells with stabilized power conversion efficiencies of (7.6 and/- 1.0)% were obtained which corresponds to 80% of the reference devices with reflective opaque gold electrodes.
