ENERGY UP-CONVERSION MATERIALS FOR DYE-SENSITIZED SOLAR CELLS

摘要

PURPOSE: energy up-conversion materials improve the efficiency of solar battery for the solar battery of dye sensitization, by absorbing light and NIR region, and there is excellent photostability to carry out deflocculant without the use of deoxycholic acid. ;CONSTITUTION: energy up-conversion materials include fist rare earth atom for dye-sensitized solar cells, and the second rare earth atom, crystal, wherein structural unit is selected from chemical formula 1-6. In chemical formula 1-6, independently for 1-10, R is phenyl or C1-C5 alkylidenes, R ' C1-5 alkyl by m, n, p, q, r and s. Crystal is selected from including YF3, NaYF4, KY3F10, LuPO4 and YbPO4. ;The 2012 of copyright KIPO submissions
