Description
Summary:In this work, enhanced poly（3-hexylthiophene）：[6,6]-phenyl-C61-butyric acid methyl ester （P3HT：PCBM） bulk- heterojunction photovoltaic devices are achieved via slow-solvent-vapour treatment. The correlations between the morphology of the active layer and the photovoltaic performance of polymer-based solar cell are investigated. The active layers are characterized by atomic force microscopy and optical absorption. The results show that slow-solvent- vapour treatment can induce P3HT self-organization into an ordered structure, leading to the enhanced absorption and efficient charge transport.
