Ionic liquid crystal as a hole transport layer of dye-sensitized solar cells

摘要

Use of a new ionic liquid crystal,l-dodecyl-3-methylimidazo-lium iodide,and iodine as an electrolyte of dye-sensitized solar cells leads to a high short circuit photocurrent density and a high light-to-electricity conversion efficiency,due to a self-assembled structure of the imidazolium cations,resulting in high conductivity of the electrolyte.
