Space-based solar power advances with microwave and laser transmission, orbital assembly, and cost reductions, aiming for ...

Solar cells are made from semiconductors whose ability to respond to light is determined by their band gaps (energy gaps). Different colors have different energies, and no single semiconductor has a ...

A new single molecule can absorb the full spectrum of sunlight and turn it into valuable hydrogen. Freeing hydrogen to use as fuel is a major science holy grail in the 21st century. Costly, ...

Solar physicists say they have found a key source of intense gamma rays unleashed when Earth's nearest star produces its most ...

Researchers have created a dye-sensitized photocatalyst that captures long-wavelength visible light to double solar hydrogen ...

(Nanowerk News) The sunlight received by Earth is a mixed bag of wavelengths ranging from ultraviolet to visible to infrared. Each wavelength carries inherent energy that, if effectively harnessed, ...

Researchers developed a solar collector with a dielectric Bragg mirror, optimizing energy conversion by separating sunlight ...

Researchers in Canada have conducted a series of simulations to understand how spectrum splitters may raise the efficiency of two-terminal tandem solar cells and have found that efficiency gains may ...
