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 ...
Micro fuel cells made of glass — power for your iPad?
Read more on Yale News Engineers at Yale University have developed a new breed of micro fuel cell that could serve as a long-lasting, low-cost, and eco-friendly power source for portable electronic devices, such as tablet computers, smart phones, and remote sensors. The researchers describe the novel device in a paper published online in the journal Small. An alternative to a battery, a fuel cell is an electrochemical device that combines hydrogen and oxygen to produce energy, giving off only water and heat as byproducts. But the materials and methods commonly used for making micro fuel cells are fragile, inefficient, and expensive. Major ...
Improving the Assembly Speed, Quality, and Tunability of Thin Conductive Multilayers
While inhomogeneous thin conductive films have been sought after for their flexibility, transparency, and strength, poor control in the processing of these materials has restricted their application. The versatile layer-by-layer assembly technique allows greater control over film deposition, but even this has been hampered by the traditional dip-coating method. Here, we employ a fully automated spin-spray layer-by-layer system (SSLbL) to rapidly produce high-quality, tunable multilayer films. With bilayer deposition cycle times as low as 13 s (50% of previously reported) and thorough characterization of film conductance in the near percolation region, we show that SSLbL permits nanolevel control over film ...
