(Phys.org)—It may sound counterintuitive that replacing one of the most photosensitive solar cell materials with a material with less desirable photosensitive properties can improve the solar cell's efficiency, but that's ...
(Phys.org)—For many years, researchers have strived to reach the goal of 10% efficiency for polymer-based organic photovoltaic (OPV) solar cells, a target widely considered to be the threshold for commercial applications. ...
(Phys.org) -- By taking advantage of graphene’s favorable electrical and optical properties, and then adding an organic dopant, researchers have achieved the highest power conversion efficiency yet for a graphene-based ...
(PhysOrg.com) -- "There is a lot of interest in creating more efficient solar cells that are also simpler than many of the designs common now," Wladek Walukiewicz tells PhysOrg.com. "We think that, through the mixing of certain ...
A new study published today in Nature Sustainability has found that using hydropower dams to generate low emission energy can cause problems for other economic sectors such as food production unless smart designs are employed.

A team of researchers at Nankai University has developed a thermal management multi-layer material that responds to heat or cold by folding or unfolding itself without the need for an external power source. In their paper ...
The high efficiency, light weight and flexibility of the latest solar cell technology means photovoltaics could provide all the power needed for an extended mission to Mars, or even a permanent settlement there, according ...
