Ionic-Liquid-Based,Sustainable Wavelength-Shifting Materials for Energy Conversion:A Minireview

摘要

Photon upconversion(UC)and down-conversion(DC)are the technology that can increase solar utilization efficiencies.UC and DC are the major key factors for designing and developing efficient organic solar cells.In this mini-review,we have focused on the recent progress on the ionic liquids(ILs)as novel sustainable media or building blocks for the fabrication of up and down-converted materials in which energy is migrated through Dexter type of energy transfer by triplettriplet annihilation(TTA)and Forster resonance energy transfer(FRET)mechanism to overcome the problems for the use of these phenomena for solar utilization efficiencies associated with conventional solvents.We have surveyed most of the important,recent,and exemplary articles and tried to provide the latest information to help researchers to grab updated knowledge in this field.Finally,we critically assess the potentiality of these sustainable media-based up and downconverters to fulfill the requirements for solar utilization efficiencies conceptually.
