摘要：

The performance of flexible organic solar cells（OSCs）significantly relies on the quality of transparent flexible electrode.Here,we used silver nanowires（AgNWs）with various weight ratios to dope high-conductive poly（3,4-ethylenedioxythiophene）:polystyrene sulfonate（PH1000）to optimize the optical and electronic properties of PH1000 film.A high-quality flexible composite electrode PET/Ag-mesh/PH1000:AgNWs-20 with smooth surface,a low sheet resistance of 6Ω/sq and a high transmittance of 86%at 550-nm wavelength was obtained by doping 20 wt%AgNWs to PH1000（PH1000:AgNWs-20）.The flexible OSCs based on the PET/Ag-mesh/PH1000:AgNWs-20 electrode delivered a power conversion efficiency（PCE）of12.07%with an open circuit voltage(V;)of 0.826 V,a short-circuit current density(J;)of 20.90 m A/cm;and a fill factor（FF）of69.87%,which is the highest reported PCE for the flexible indium-tin oxide（ITO）-free OSCs.This work demonstrated that the flexible composite electrodes of PET/Ag-mesh/PH1000:AgNWs are promising alternatives for the conventional PET/ITO electrode,and open a new avenue for developing high-performance flexible transparent electrode for optoelectronic devices.
