Solving the solar cell power conversion dilemma
Nano-LEDs emit full visible spectrum of light
How to make a "perfect" solar absorber
The key to creating a material that would be ideal for converting solar energy to heat is tuning the material's spectrum of absorption just right: It should absorb virtually all wavelengths of light that ...
New solar cell technology captures high-energy photons more efficiently
(Phys.org) —Getting the blues is rarely a desirable experience—unless you're a solar cell, that is.
Toward a truly white organic LED: Physicists develop polymer with tunable colors
By inserting platinum atoms into an organic semiconductor, University of Utah physicists were able to "tune" the plastic-like polymer to emit light of different colors – a step toward more efficient, less ...
Data from Voyager 1 point to interstellar future
(Phys.org) -- Data from NASA's Voyager 1 spacecraft indicate that the venerable deep-space explorer has encountered a region in space where the intensity of charged particles from beyond our solar system has ...
New approach may be key to quantum dot solar cells with real gains in efficiency
(Phys.org) —Los Alamos researchers have demonstrated an almost four-fold boost of the carrier multiplication yield with nanoengineered quantum dots. Carrier multiplication is when a single photon can excite ...
Berkeley Lab scientists identify new driver behind Arctic warming
Scientists have identified a mechanism that could turn out to be a big contributor to warming in the Arctic region and melting sea ice.
Novel negative-index metamaterial that responds to visible light designed
A group of scientists led by researchers from the California Institute of Technology has engineered a type of artificial optical material—a metamaterial—with a particular three-dimensional structure such ...
