Nanotechnology breakthrough enables conversion of infrared light to energy

Phys.org  October 31, 2019
Invisible infrared light accounts for half of all solar radiation on the Earth’s surface, yet ordinary solar energy systems have limited ability in converting it to power. A team of international researchers (Sweden, China) has developed film combining nanocrystals with chains of microlenses that can be applied on top of ordinary solar cells. The ability of the microlenses to concentrate light allows the nanoparticles to convert the weak IR light radiation to visible light which is useful for solar cells increasing their efficiency by 10 percent or more…read more.
