Arable land is at an all-time premium. Since the last ice age, humans have cleared one-third of the earth’s forests and two-thirds of its wild grasslands, much of it for agriculture. And as the world ...

US scientists have discovered that using wavelength-selective, semi-transparent PV modules to absorb the blue light spectrum while transmitting red light onto crops can increase crop yield. “Today’s ...

Researchers have engineered tiny gold nanospheres that can soak up almost the entire spectrum of solar energy, promising a step change in how efficiently we turn sunlight into usable power. By packing ...

Sunlight carries more energy than most solar devices can catch. That gap matters as heat waves grow worse. It also matters as grids strain under rising demand. A team working at the KU R&D Center at ...

Solar cells are an increasingly important source of renewable energy, but there’s still room for improvement. Stanford engineers have now developed a pyramid-shaped lens that can focus sunlight from ...

Global energy demands mandate scalable, efficient generation technologies to replace aging legacy infrastructure.

Researchers in Canada have conducted a series of simulations to understand how spectrum splitters may raise the efficiency of two-terminal tandem solar cells and have found that efficiency gains may ...
