Highly Efficient and Bendable Organic Solar Cells with Solution-Processed Silver Nanowire Electrodes

Highly efficient and bendable organic solar cells (OSCs) are fabricated using solution-processed silver nanowire (Ag NW) electrodes. The Ag NW films were highly transparent (diffusive transmittance approximate to 95% at a wavelength of 550 nm), highly conductive (sheet resistance approximate to 10 sq(-1)), and highly flexible (change in resistance approximate to 1.1 +/- 1% at a bending radius of approximate to 200 m). Power conversion efficiencies of approximate to 5.80 and 5.02% were obtained for devices fabricated on Ag NWs/glass and Ag NWs/poly(ethylene terephthalate) (PET), respectively. Moreover, the bendable devices fabricated using the Ag NWs/PET films decrease slightly in their efficiency (to approximate to 96% of the initial value) even after the devices had been bent 1000 times with a radius of approximate to 1.5 mm.
