Northwestern University scientists have now developed a carbon nanotube solar cell (CNT) that is twice as efficient as its predecessors. Early research stalled when CNTs proved to be inefficient, converting far less sunlight into power than other methods. Yet the CNTs have long shown promise for photovoltaics because they’re lighter, more flexible, and cheaper than [...]

A Michigan State University research team has developed a new type of solar concentrator that when placed over a window creates solar energy permitting the ability to actually see through the window. The new technology is called a transparent luminescent solar concentrator and can be used on buildings, cell phones and any other device that [...]

A system proposed by researchers at MIT recycles materials from discarded car batteries into new, long-lasting solar panels that provide emissions-free power. Lead acid car batteries are a potential source of lead pollution, which makes the idea a classic win-win solution. The system is described in a paper in the journal Energy and Environmental Science, [...]

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 [...]
