Researchers at the University of Illinois at Urbana-Champaign use a printing process to assemble tiny cells into multilayer stacks for extraordinary levels of photovoltaic conversion efficiency.
As an energy source, the Sun has always been a dependable provider. Although it freely shines on everyone, the ability to capture and convert the Sun’s abundant energy is anything but free. However, new technologies aimed at achieving “full spectrum” operation in utility-scale photovoltaics may soon make solar energy a viable option.
