PROBLEM TO BE SOLVED: To improve durability and enhance photoelectric conversion efficiency by using at least one kind of polyhalogenide complex as a photosensitizing agent. SOLUTION: As a polyhalogenide complex, especially polyiodide complex or polyiodide ion is used. The polyiodide ion is expressed by a formula Izn+1 <1-> , wherein n is an integer exceeding 2 and usually not exceeding about 5. Iodine ion/iodine molecular system transmits electron by redox reaction, however, since it occurs in generation reaction in polyiodide complex simultaneously with the decomposition reaction in addition to the function, solar light energy conversion efficiency is not lowered practically owing to the deterioration of a photosensitizing agent. Therefore, the system is superior in durability and has high photoelectric conversion efficiency.
