Abstract:
A photoelectric conversion element, comprising:a first electrode; a second electrode arranged opposite to the first electrode; an electron transport layer arranged between the first electrode and the second electrode, at least a part of the electron transport layer being porous; a dye layer which is in contact with the electron transport layer; a hole transport layer arranged between the electron transport layer and the second electrode; and short-circuit preventing moans, adjacent the first electrode, that prevents or suppresses a short-circuit between the first electrode and the hole transport layer; the short-circuit preventing means including a barrier layer having a porosity smaller than the porosity of the electron transport layer, wherein when the porosity of the barrier layer is defined by A% and the porosity of the electron transport layer is defined by B%, the value of B/A is equal to or greater than 10.
