Drexel researchers are investigating the development of new materials and architectures for nanostructured solar cells. The amount of solar power incident upon the earth is 10,000 times larger than global power consumption. Converting sunlight to electricity represents a sustainable and robust solution to the world's energy problem. Nanostructured solar cells offer the potential for low processing and material costs while maintaining reasonably high efficiencies. Work at Drexel focuses on understanding the relationships between processing, material and interfacial properties, and solar cell performance. A number of different solar cell designs are currently being investigated, including dye sensitized solar cells, extremely thin absorber solar cells, quantum dot solar cells, and organic solar cells. New combinations of materials, new manufacturing methods, and new solar cell designs are being studied to understand fundamental limitations in performance and reliability and to improve device efficiency and lifetime.
