Gwangju Institute of Science and Technology (GIST) scientists have discovered that the amount of alkali metal introduced into crystals of flexible thin-film solar cells influences the path that charge carriers take to traverse between electrodes, thereby affecting the light-to-electricity conversion efficiency of the solar cell. The press release asserts that given the immense application potential […]

University of York solar panel designs in checkerboard lines increases their ability to absorb light by 125 percent, a new study says. Researchers say the breakthrough could lead to the production of thinner, lighter and more flexible solar panels that could be used to power more homes and be used in a wider range of […]

Chinese Academy of Sciences researchers have designed a kind of ‘tiny wind turbine’ that can scavenge wind energy from breezes as little as those created by a brisk walk. The method is a low-cost and efficient way of collecting light breezes as a micro-energy source. Most of the wind available on land is too gentle […]

A Penn State research team suggests that using two thin films of different materials may be the way to go to create affordable, thin film cells with about 34% efficiency. Solar cells have come a long way, but inexpensive, thin film solar cells are still far behind the more expensive, crystalline solar cells in efficiency. […]

Oak Ridge National Laboratory and the University of Tennessee, Knoxville have discovered a way to slow phonons, the waves that transport heat. The discovery could improve novel hot-carrier solar cells, which convert sunlight to electricity more efficiently than conventional solar cells by harnessing photogenerated charge carriers before they lose energy to heat. ORNL’s Michael Manley […]
