Outline of Final Research Achievements

In this study, I used a photonic curing process to prepare a novel CNT hybrid film as a transparent electrode. This film exhibited an extremely durable sheet resistance of 60 Ω/□ at 85% transmittance. Organic photovoltaics were fabricated on the stable CNT hybrid film by evaporating small molecules. The optimum cell exhibited a power conversion efficiency of 3.0%, which was very close to the OPV cell on commercial indium-tin-oxide.
