The fluorescent future of solar cells – our work highlighted by Yale news
For some solar cells, the future may be fluorescent. Scientists at Yale have improved the ability of a promising type of solar cell to absorb light and convert it into electrical power by adding a fluorescent organic dye to the cell layer. This squaraine dye boosts light absorption and recycles electrons, improving the conversion of light into energy. The results suggest a new route for the development of lower-cost, higher-efficiency photovoltaics, the scientists said. “People can apply our approach in designing advanced solar cells with higher efficiencies,” said André D. Taylor, the assistant professor of chemical and environmental engineering at Yale who ...
Yale news coverage of our carbon nanotube/silicon hybrid solar cell
New carbon films improve prospects of solar energy devices New research by Yale University scientists helps pave the way for the next generation of solar cells, a renewable energy technology that directly converts solar energy into electricity. In a pair of recent papers, Yale engineers report a novel and cost-effective way to improve the efficiency of crystalline silicon solar cells through the application of thin, smooth carbon nanotube films. These films could be used to produce hybrid carbon/silicon solar cells with far greater power-conversion efficiency than reported in this system to date. “Our approach bridges the cost-effectiveness and excellent electrical and optical properties ...
“Scalable Fabrication of Multifunctional Freestanding Carbon Nanotube/Polymer Composite Thin Films for Energy Conversion”
Translating the unique properties of individual single-walled carbon nanotubes (SWNTs) to the macroscale while simultaneously incorporating additional functionalities into composites has been stymied by inadequate assembly methods. Here we describe a technique for developing multifunctional SWNT/polymer composite thin films that provides a fundamental engineering basis to bridge the gap between their nano- and macroscale properties. Selected polymers are infiltrated into a Mayer rod coated conductive SWNT network to fabricate solar cell transparent conductive electrodes (TCEs), fuel cell membrane electrode assemblies (MEAs), and lithium ion battery electrodes. Our TCEs have an outstanding optoelectronic figure of merit σdc/σac of 19.4 and roughness ...
