Sustainable solvent platform for photon upconversion increases solar utilization efficiency

(Tokyo Institute of Technology) Scientists at Tokyo Institute of Technology (Tokyo Tech) havedeveloped a new low-cost, environmentally friendly photon upconversion platform thatachieves high thermal stability using deep eutectic solvents. Deep eutectic solvents are anemerging class of solvents that are a cost-effective and sustainable alternative to ionicliquids.
