Subject:    Development of Nanomaterials for Highly Efficient Dye-sensitized Solar Cells


Abstract: The development of technology for sustainable energy is a crucial challenge for the 21st century. A recent analysis has confirmed that the conversion of solar energy into electricity by solar cells is one of the most promising renewable energy technologies. Among the solar cells, nanoporous semiconductor based dye-sensitized solar cells (DSSCs) and perovskite solar cells have gained much interest in recent years because of their low production costs and ease of fabrication. The performance of the dye-sensitized solar cells depends on the semiconductor thin filmmaterial, thin film morphology, structure of the sensitizing molecules and redox mediator used. The terfacial recombination of the electrons injected by the sensitizer with the cations of the dye molecule or redox couple limits the efficiency of the DSSCs. It has been found that the coating of nsulating layer on nanoporous semiconductor oxide material greatly suppresses the recombination in DSSCs and thereby increases the overall cell efficiency. The coating of insulating shell layer on the core semiconductor oxide material may be an interesting approach to reduce the interfacial recombination in DSSCs. Therefore, our recent research has been focused on the development of core/shell ructured nanomaterials by various solution growth techniques. In this study, widely applicable and elatively simple approach for the successful preparation of core/shell structured semiconductor oxide thin films will be discussed.
