(Phys.org)—When exposed to air, a luminescent 2D material called molybdenum telluride (MoTe2) appears to decompose within a couple days, losing its optical contrast and becoming virtually transparent. But when scientists ...
(Phys.org) —As the world's dependence on fossil fuels causes ever-increasing problems, researchers are investigating solar fuels as an alternative energy source. To make solar fuels, sunlight is converted into hydrogen ...
(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 ...
(PhysOrg.com) -- Currently, the cost of electricity from commercial silicon solar cells is about 10 times higher than the cost of utility-scale electricity. In order to make solar cells cost-competitive with currently available ...
The sun delivers more energy to Earth in one hour than humanity consumes over an entire year. Scientists worldwide are searching for materials that can cost-effectively and efficiently capture this carbon-free energy and ...

During photosynthesis, natural leaves with elaborate architectures and functional components can harvest and convert solar energy into chemical fuels that are converted into energy. The biological energy production has provided ...
A closer look at materials that make up conventional solar cells reveals a nearly rigid arrangement of atoms with little movement. But in hybrid perovskites, a promising class of solar cell materials, the arrangements are ...
