Abstract
The purpose of the present invention is to provide an easy-to-manufacture organic-inorganic hybrid photoelectric conversion element having high photoelectric conversion efficiency and excellent durability. A photoelectric conversion element 1 further comprises a closely packed titanium oxide layer 4, a porous titanium oxide layer 5, an organic-inorganic hybrid crystal layer 6, and a hole transport layer 7 between a first conductive layer 3 and a second conductive layer 8, wherein the hole transport layer 7 comprises a compound with the following structure (I): where R1 to R4 are each the same or different and represent hydrogen atom, substituted or unsubstituted alkyl group, substituted or unsubstituted alkylamino group, substituted or unsubstituted arylamino group, or substituted or unsubstituted alkoxy group, provided that a case in which all of the R1 to R4 are hydrogen atom is excluded; and m, n, o, and p are each the same or different and represent an integer of 1 to 5, provided that when any of the m, n, o, and p is an integer of 2 or more, the corresponding R groups may each be the same or different.
