PROBLEM TO BE SOLVED: To prevent short-circuit inside of an element without deteriorating the photoelectric converting performance by mounting a spacer layer including the substantially insulating particles between a semiconductor fine particle layer and a counter electrode, forming the element with a conductive base and a charge moving layer. SOLUTION: A photoelectric converting element sensitized by a coloring matter, consists of a conductive base, a semiconductor film (photosensitive layer) mounted on the conductive base and sensitized by a coloring matter and the like, a charge moving layer and a counter electrode. In the photoelectric converting element, a spacer layer substantially composed of insulating particles, is mounted between the semiconductor film and the counter electrode for preventing the short-circuit therebetween. As the substantially insulating particles, the oxide glass or crystalline oxide as a substance of below 10-3 siemens/cm of conductivity is used. The insulating particles, for example, the oxide glass including silicon, boron or phosphorus, have a particle size of 5-1000 times of that of the semiconductor fine particles acting as the electrode, preferably 5-1000 times. |
