A team at the U.S. National Renewable Energy Laboratory has come up with a new process that would reduce the production cost of highly expensive – and highly efficient – gallium arsenide cells.

Scientists have achieved a technological breakthrough for solar cells previously thought impossible. Scientists at the National Renewable Energy Laboratory (NREL) achieved a technological breakthrough ...

Gallium Phosphide (GaP) epitaxy on silicon substrates represents a critical frontier in semiconductor heterointegration, combining the superior optoelectronic properties of III–V materials with ...

Offered in red, blue, yellow, and true-green versions, the TLC series of LEDs features luminous intensity as high as 20,000 mcd. The devices are built on aluminum-indium-gallium-phosphide (for red and ...

One of the most promising forms of artificial photosynthesis involves using solar energy to split liquid water to produce oxygen and hydrogen gas, which can be stored and used as a clean fuel. And one ...

“We don’t need any energy input, and it bubbles hydrogen like crazy. I’ve never seen anything like it,” said UCSC Professor Scott Oliver, describing a new aluminum-gallium nanoparticle powder that ...

Scanning electron microscopy of the composite shows aluminum nanoparticles in a matrix of gallium. (Credit: Amberchan et al., 2022) Aluminum is a highly reactive metal that can strip oxygen from water ...

X-ray diffraction shows that the high-pressure modifications (at 22 to 130 kilobars) of the antimonides of indium, gallium, and aluminum are analogous to white tin. The arsenide and phosphide of ...
