제목 Ultra-flat and Foldable Transparent Conducting Electrodes for organic photovoltaics applications
초록 We report a novel architecture to fabricate solution-processed foldable transparent conducting electrodes by using a combination of metal-grid embedded into flexible substrate and ultrathin transparent electrodes. The use of the silver metal grid and the PEDOT:PSS layer in combination resulted in an increase in conductivity without a reduction in the transmission and helped in overcoming the trade-off between them, leading to highly transparent (optical transmittance ≈ >85% at a wavelength of 550 nm), highly conducting (sheet resistance ≈ 20 ohm/sqr.) and extremely flexible (bending radius ≈ 200 um) electrodes with very flat surface (root-mean-square roughness ≈ 0.5 nm). These electrodes were used to fabricate foldable organic devices that exhibited performances similar to that of devices fabricated on glass substrate. In addition, these fabricated flexible devices did not show degradation in their performance even after being folded.
