DYE SENSITIVE SOLAR CELL WITH IMIDAZOLIUM BASED LIQUID TYPE ELECTROLYTE FOR PROLONGING LIFETIME AND IMPROVING ENERGY CONVERSION EFFICIENCY

摘要

PURPOSE: A dye sensitive solar cell is provided to prolong the lifetime and to improve energy conversion efficiency by using a 1,3-vinylalkylimidazolium iodide material capable of keeping itself in a liquid state at a room temperature or at a high temperature as an electrolyte. CONSTITUTION: A dye sensitive solar cell includes a semiconductor electrode(10), an opposite electrode(20) and a 1,3-vinylalkylimidazolium iodide based electrolyte. The 1,3-vinylalkylimidazolium iodide based electrolyte(30) is interposed between the semiconductor electrode and the opposite electrode.
