Abstract: The LSC-PM concept is introduced and its performances are characterized using a light-limited reaction as a probe to measure the increased photon flux to the reaction channels.
Firstly, by using blue LED light as light source, the wavelength conversion capabilities of the device are demonstrated with a 10-time increase in photon flux to the reaction mixture.
Secondly, the light transport within the waveguide is proved by a 6-fold increase in the reaction apparent kinetic in the LSC-PM compared to the non-doped analog.
Then, in solar simulated conditions, the LSC-PM with 200ppm dye-doping showed a 4-fold increased photon flux with respect to the non-doped control reactor.
Finally, a significant different between LSC-PM and a transparent reactor is observed also in an outdoor experiment with natural sunlight irradiation.Summary: The Luminescent Solar Concentrator-Photomicroreactor (LSC-PM) is an innovative device for solar-powered continuous-flow photochemistry. It is constituted by an LSC lightguide that harvests solar photons and delivers them downshifted to the embedded microflow reactor.References: D. Cambié, C. Bottecchia, N.J.W. Straathof, V.
