The research team's semi-transparent solar concentrator can be directly coated onto standard window glass. It uses liquid crystal films to reflect and guide circularly-polarized sunlight to solar cells installed toward the edge of a window. A 1-inch diameter prototype was found capable of directly powering a 10 mW fan under sunlight.A research team based at China's Nanjing University has developed a transparent, colorless and unidirectional solar concentrator compatible with existing windows. Solar concentrators are designed to converge solar energy onto the side of architectural glass. Useful ...Den vollständigen Artikel lesen ...
