Most solar cells used in homes and industry are made using thick layers of material to absorb sunlight, but have been limited in the past by relatively high costs. Many new, lower cost designs are limited as their layer of light-absorbing material is too thin to extract enough energy.
A trio of researchers at North Dakota State University and the University of South Dakota have turned to computer modeling to help decide which of two competing materials should get its day in the sun as the nanoscale energy-harvesting technology of future solar panels -- quantum dots or nanowires.
Most efforts at improving solar cells have focused on increasing the efficiency of their energy conversion, or on lowering the cost of manufacturing. But now MIT researchers are opening another avenue for improvement, aiming to produce the thinnest and most lightweight solar panels possible.
A market research firm said Japan is set to overtake both Japan and the USA in the installation of photovoltaic (PV) capacity.
It’s not surprise that having both a green roof and a solar panel array on a building is a great way to double down on reducing energy bills for property owners.
MIT's created a new type of glass that's glare-free, self-cleaning and anti-fogging - useful for everything from car windscreens and scuba goggles to cellphones and solar panels.
With budget battles looming, the U.S. Department of Energy (DOE) made a preemptive strike in support of one of its boldest clean-energy programs, the Advanced Research Project Agency-Energy (ARPA-E), detailing how six projects that received $23.6 million in seed funding had gone on to pull in more than $100 million in venture capital investment.
It's all about the mission. That's been the overriding message from the various branches of the U.S. military as they pursue renewable-energy solutions - and Marines in Afghanistan are providing real-world evidence to back that up.
Researchers have developed a system allowing large-scale solar power installations to keep themselves clean, based on technology developed for missions to Mars.
The National Institute of Standards and Technology (NIST) is using organic semiconductors as a basis for spray-on large-area electronics such as solar cells and displays.
