An Italian startup has developed a luminescent solar concentrator technology that can be integrated with active architectural elements and windows. The technology is based on nanoparticles known as chromophores, which decouple the absorption and light-emission processes, thanks to appropriate engineering. The company claims it has achieved a conversion efficiency of up to 3.2%, with a degree of transparency in the visible spectrum of around 80%.
A University of Michigan team hopes to offer a 15% efficient solar window product, which allows 50% of the light through. It has received US$1.3 million from the Department of Energy’s Solar Energy Technologies Office to develop the idea further.
Italy-based Glass to Power has raised €2.25 million via crowdfunding to advance its plans for the roll out of an industrial production line for its transparent solar PV windows. The product is expected to be marketed in 2019.
Ferdinand Grapperhaus, CEO of PowerWindow developer Physee, discusses the company’s innovative approach to bringing more solar power into the home and C&I buildings.
