A new twist on an old solar cell design sends light ricocheting through layers of microscopic spheres, increasing its electricity-generating potential by 26 percent. By engineering alternating layers of nanometer and micrometer particles, a team of engineers from the University of Minnesota has improved the efficiency of a type of solar cell by as much as 26 percent. These cells, known as dye-sensitized solar cells (DSSC), are made of titanium dioxide (TiO2), a photosensitive material that is...

MIT reported on Monday that researchers have a used genetically modified virus to produce structures that improve solar-cell efficiency by about one-third. MIT researchers said they have found a way to make significant improvements to the power-conversion efficiency of solar cells by using a tiny virus to perform detailed assembly work at the microscopic level. Sunlight hits a light-harvesting material in a solar cell, which releases electrons that can produce an electric current. ...

KARLSRUHE, Germany, April 14, 2011 /PRNewswire/ -- The exploitation and utilization of new energy sources are considered to be among today's major challenges. Solar energy plays a central role, and its direct conversion into chemical energy, for example hydrogen generation by water splitting, is one of its interesting variants. Titanium oxide-based photocatalysis is the presently most efficient, yet little understood conversion process. In cooperation with colleagues from Germany and...

Research could lead to cheap, clean ways to produce hydrogen for use in fuel cells A little disorder goes a long way, especially when it comes to harnessing the sun's energy. Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) jumbled the atomic structure of the surface layer of titanium dioxide nanocrystals, creating a catalyst that is both long lasting and more efficient than most materials in using the sun's energy to extract hydrogen from...

MOUNTAIN VIEW, Calif., July 27 /PRNewswire/ -- Propelled by aggressive R&D activities, third generation photovoltaics (PVs) are poised to take a huge leap forward. The exploratory mass production of dye-sensitized solar cells (DSSC)-powered consumer durables is likely to alter the future course of research in this segment. Some of the first commercial third generation products are DSSC-powered backpacks and mobile phones. Several developers are working to take advantage of DSSCs'...

Thanks to two technologies developed by Professor Benoît Marsan and his team at the Universit© du Qu©bec à Montr©al (UQAM) Chemistry Department, the scientific and commercial future of solar cells could be totally transformed. Professor Marsan has come up with solutions for two problems that, for the last twenty years, have been hampering the development of efficient and affordable solar cells. His findings have been published in two...
