Description
Summary:A surface-interpenetrated conducting polymer, PANI:CSA on plastic substrate, especially cheap PET significantly boosts mechanical properties for outstanding performance as an ITO-free organic electrode in flexible organic solar cells and exhibits best performance of an average power conversion efficiency of 3.5±0.2% under 100mW/cm2 illumination, with a short-circuit current density of 8.7mA/cm2, an open-circuit voltage of 0.83V, and a fill factor of 0.49 comparable to conventional organic solar cells made with ITO electrodes on glass or PET. A surface-interpenetrated conducting polymer, PANI:CSA on plastic substrate, especially cheap PET, electrode significantly boosts mechanical properties for an outstanding performance as an ITO-free organic electrode in flexible organic solar cells and exhibits best performance. [Display omitted] ► Mechanical reinforced conducting polymer electrode was prepared on a plastic substrate. ► High efficiency ITO-free organic solar cells were fabricated on cheap PET film. ► Surface interpenetration enhances the adhesion between conducting polymer and PET.
