NEW TYPE HIGH EFFICIENT QUASI-SOLID-STATE IONIC LIQUID ELECTROLYTES FOR DYE-SENSITIZED SOLAR CELLS

摘要

In this article, for the fist time we reported the preparation of a mostly solid-state high efficient electro-conductive material comprising 1-methyl-3-propylimidazolium iodide (MPII), benzimidazole (BI), iodine and lithium iodide. In this electrolyte, BI act not only additives but also gelators. With their significant electrochemical properties, overall efficiency of 3.07% was achieved under AM 1.5 (100mW/ cm2).
