Shanhui Fan, an electrical engineering professor at Stanford University in California has found a way to let photovoltaic solar cells cool themselves by shepherding away unwanted thermal radiation. By adding a specially patterned layer of silica glass to the surface of ordinary solar cells, a team of researchers may have overcome one of the major [...]

Scientists have reviewed chemists’ work on “singlet fission,” a process in which a single photon generates a pair of excited states. Singlet fission as a 1->2 conversion process has the potential to boost solar cell efficiency by as much as 30 percent. Chemists at the University of California, Riverside published a perspective article published last [...]

Researchers at the Energy Department’s National Renewable Energy Laboratory (NREL) are analyzing the new material, perovskite, using the lab’s unique testing capabilities and broad spectrum of expertise to uncover the secrets and potential of the semiconducting cube-like mineral. The NREL material is synthetic version of a mineral first found in the Ural Mountains in 1839. [...]

Scientists at Nanyang Technological University in Singapore (NTU) have developed a next-generation sunlight to electricity solar cell material which can also emit light. The solar cell is built from Perovskite, a promising material (also see this link) that could hold the key to creating high-efficiency, inexpensive solar cells. The new cells not only glow when [...]

University of Michigan (UM) researchers have invented colorful, see-through solar cells that may one day be used to make stained-glass windows, decorations and even shades that turn the sun’s energy into electricity.  The technology may also be a solution to photocell orientation to the sun problem. Jay Guo, a professor of electrical engineering and computer [...]
