Carbon Nanotubes Channel Heat into Light for Solar
The ever-more-humble carbon nanotube may be just the device to make solar panels far more efficient – and anything else that loses energy through heat. Rice University [...]
“Hotspots” Boost Solar Desalination by 50%
Solar desalination methods have been around for awhile, both for powering the process, and to help with evaporation. Rice University’s solar-powered approach for [...]
Speeding Discovery of New Solar Cell Materials
A broad class of materials called perovskites is considered one of the most promising avenues for developing new, more efficient solar cells. But the virtually limitless [...]
Compact Solar Unit Yields 250 Liters of Hydrogen per Day
The amount of energy needed to produce hydrogen, as well as the required materials has long been a challenge for renewable power researchers in order to make it scalable for [...]
NREL IDs Markets for Flexible Solar
Thin film photovoltaic (PV) cells have been a target of some skepticism due to cost and scale-up issues for high-performance microcells. However, with new advances, [...]
Solar Cell Generates Hydrogen and Electricity in Parallel
In the quest for abundant, renewable alternatives to fossil fuels, scientists have sought to harvest the sun’s energy through “water splitting,” an artificial [...]
“Solar Cell Flow Battery” Shows High Efficiency
While many utilities and solar farm developers are rushing to connect solar capacity to large batteries, a research team is taking a different approach by making the solar [...]
“Funnel Vision” May Triple Solar Efficiency
