Researchers in Europe have presented a mechanically-stacked GaAs/Ge multijunction solar cell. This is the first promising demonstrator of a novel technology to produce mechanically stacked ...

Here, using a detailed balance model, we show that limiting the emission angle of a high-quality GaAs solar cell is a feasible route to achieving power conversion efficiencies above 38% with a ...

Researchers at the US Department of Energy's National Renewable Energy Laboratory have fabricated a III-V gallium arsenide (GaAs) solar cell based on a substrate made of spalled GaAs. The cost of ...

The synthesis involved a gallium arsenide (GaAs) solar cell with a gallium indium arsenide phosphide emitter layer. NREL has unveiled a new design for III-V rear heterojunction solar cells based ...

Alta Devices, a specialist in high-performance flexible solar cells, says it has achieved a new world-best of 29.1 per cent conversion efficiency with its single-junction gallium arsenide (GaAs) ...

“We have a new method of using gallium arsenide (GaAs) material in a very effective way through nanostructuring, so we can make solar cells much more efficient using only a tiny fraction of the ...

Researchers have created a solar cell with a record 39.5 percent ... wells in the middle layer to extend the bandgap of the GaAs cell and increase the amount of light that the cell can absorb.

US-based specialist gallium arsenide (GaAs) PV manufacturer Alta Devices, a subsidiary of Hanergy Group, has achieved another new solar cell conversion efficiency record of 29.1%, which was ...

Some people like to say outer space is a starry frontier of vast emptiness, but clearly they’ve never tried launching a satellite. Sixty-five years after Sputnik, some 8,000 low-Earth orbit (LEO ...

These emissions, called luminescent emissions, are a function of the voltage across the cell. Here, we take the advantage of this fact to modulate the luminescent emissions of a GaAs solar cell to ...
