Polymer solar cells for the fabrication of cost-efficient and flexible power sources have undergone considerable development. Among the various systems, P3HT and PCBM networks have shown the highest efficiency; however, further improvement in efficiency is required for commercial applications. In addition, the current state-of-the-art cells are typically fabricated on rigid glass with ITO, and, as a result, do make a limitation for low-cost photovoltaic energy conversion due to the ever-increasing cost of indium. In this respect, we have focused on novel materials and processes for low-cost and high-efficiency PSCs. For low-cost and high-efficiency PSCs, ITO-free OSCs with conductive polymer anodes were investigated. In addition, to further enhance cell efficiencies of PSCs, changes in the nanoscale morphologies of the blend films were investigated, and polymer solar cells with periodic structures were also investigated according to various grating conditions. |
