研究期間:10108~10207;Energy is an important issue for the human being nowadays, due to the gobal warming caused by using fossil energy and the danger may be caused by the nuclear energy. Searching for the possible non-expensive alternative energy for the future use is the duty for the scientists. The objective of this three-year proposal is to develop and study the key components for the 3rd generation organic solar cells. It includes three parts: The first is the studies related to Dye-Sensitized Solar Cells, including Ru based dye, organic near infrared dye, polymer counter electrode catalyst and Pt- FTO free devices. The second part is the preparation of organic solar cell related high-performance conjugated polymers and their applications. The third part is Organic Polymer Photovoltaic Cells related studies, including the synthesis of low band-gap conjugated polymers and high conducting/mobility hole transport polymer. The ultimate goal for this proposal is to prepare the key components for high efficiency, low cost organic solar cells.
