Concentrator photovoltaics that are cheaper and easy to manufacture could reach 50% efficiency

In what could be a major step forward for a new generation of solar cells called “concentrator photovoltaics,” University of Michigan researchers have developed a new semiconductor alloy that can capture the near-infrared light located on the leading edge of the visible light spectrum. Easier to manufacture and at least 25 percent less costly than

High efficiency concentrating solar cells move to the rooftop

Ultra-high efficiency solar cells similar to those used in space may now be possible on your rooftop thanks to a new microscale solar concentration technology developed by an international team of researchers. “Concentrating photovoltaic (CPV) systems leverage the cost of high efficiency multi-junction solar cells by using inexpensive optics to concentrate sunlight onto them,” said

Flat-pack lens boosts solar power

Fresnel lens concentrates solar without bulk Micro-machining could be used to create almost flat, Fresnel lenses, that boost the electrical efficiency of solar panels, according to researchers in China. Fresnel lenses were invented by French engineer and scientist Augustin-Jean Fresnel, in the early nineteenth century, they are essential two-dimensional equivalents of conventional optical lens, but
