Optical photovoltaic converters for power transmission systems

Researchers from Spain have developed a novel model to evaluate optical photovoltaic converters used in high-power optical transmission. They have found that indium gallium nitride (InGaN) and indium aluminum nitride (InAlN) semiconductors could provide better results than gallium arsenide (GaAs).

EU Chips Act proposed to address semiconductor shortages

The European Commission wants to introduce legislation to back semiconductor research and to address the immediate problem of supply chain bottlenecks by drumming up more than €43 billion, with member states and the private sector expected to contribute.

US scientists develop new process to make stacks of semiconductors just a few atoms thick

R&D departments at the University of Chicago and Cornell University have pieced together a new atomic scale semi-conductor manufacturing procedure that can provide “the foundation for modern integrated circuitry”.

New alloy could pave the way for next generation solar cells

Researchers at the University of Michigan have developed a new semiconductor alloy that can capture near-infrared light in the leading edge of the visible light spectrum. This could be a major step forward the development of a new generation of solar cells called “concentrator photovoltaics”.
