(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 ...
Moderate-temperature thermal sources often radiate waste heat as a by-product of mechanical work, chemical or nuclear reactions, or information processing. In a new report in Science, Paul S. Davids and a research team at ...
A University of California, Riverside assistant professor has combined photosynthesis and physics to make a key discovery that could help make solar cells more efficient. The findings were recently published in the journal ...
