Acceptor molecule upconverts low-energy green light to high-energy purple with high effici

Solar cells and photocatalysts can be surprisingly inefficient. Despite light consisting of many wavelengths, the range that even highly efficient devices use is limited. Other wavelengths, especially long wavelengths, simply pass through the material without being used as energy
