Abstract:

A high performance flexible polymer solar cells(PSCs) are obtained by using a flexible, transparent composite electrode based on silver nanowire(AgNW) with doctor blading method. The AgNW-based flexible composite film(APA) consisting of AgNWs, polyvinyl butyral(PVB) and Al-doped ZnO(AZO) nanoparticles was readily prepared by multi-layer doctor blading on the poly(ethylene terephthalate)(PET) substrate at moderate temperature. The transparent APA composite film prepared on the PET substrate exhibits superior opto-electrical properties with a high transmittance of 90.90% at 550 nm and a low sheet resistance of 13.01 Ω/sq. The flexible PSCs employing the transparent APA/PET substrate obtain power convention efficiency(PCE) of 5.47%. Moreover, the PCE falls only 14% after bending for 1000 cycles with a bending radius of 5 mm.
