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 ...

Solar filters emit a red light over tomato plants growing in a research field at UC Davis in 2022. The work further tests the findings of a UC Davis study showing plants in agrivoltaic systems respond ...

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 ...

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 ...
