摘要
This paper describes the efficiency of solar cells that have been prepared by mixing quantum dots (QD) in gel polymer electrolytes (GPEs) based on plasticized cellulose acetate. Copper indium sulfide/zinc sulfide (CuInS/ZnS) QD was doped into GPEs and was characterized for application in a dye-sensitized solar cell (DSSC). The addition of QD into GPEs increases the conductivity up to 1.6 x 10(-1) S cm(-1) at room temperature made them a promising electrolyte for DSSC. Atomic force microscopy analysis affirmed the uniform distribution of QD into the polymer matrix. The photovoltaic efficiency performance of DSSC using QD-doped GPE electrolyte was found to be increased up to 8.02%.
