Radiative cooling for CPV systems

Scientists in the United States have tested soda-lime glass radiative coolers in a CPV system and claim these can reduce the device operating temperature by 5 to 36 degrees Celsius. This may result in an increase in the solar cell’s open-circuit voltage of between 8% and 27%.

Scientists hit 21.6% perovskite cell efficiency using concentrator PV

An international research group achieved the result on a 9 sq mm, triple-cation based, n-i-p structured perovskite cell using low solar concentration levels. Device instability, however, remains a challenge.

U.S. university CPV system outperforms silicon by 54% in test

A single-cell concentrating photovoltaic system developed by researchers at Penn State University reportedly reached 30% efficiency, and generated 54% more energy during a two-day test than a commercial silicon solar in the same conditions.

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”.
