Photon upconversion facilitated molecular solar energy storage

Photon upconversion is used to facilitate the production of a solar fuel. This is done by collocating a triplet-triplet annihilation upconversion systemin a microfluidic device with a molecular solar thermal energy storage system. Incoherent truncated white light is used to drive the reaction and the green part of the spectrum is upconverted to blue light, which in turn is absorbed by the solar fuel.
