Photoelectric conversion element, photoelectric conversion module, electronic device, and power supply module

A photoelectric conversion element, comprising:

• a first electrode;
• a photoelectric conversion layer over the first electrode;
• a second electrode over the photoelectric conversion layer;
• and
• a surface protection portion adjacent to a face of the second electrode where the face does not face the photoelectric conversion layer,
• the surface protection portion containing a compound derived from a fluorine-based silane compound having at least one alkoxysilyl group;
• and
• a sealing member comprising an adhesive member and a gas barrier member, wherein said adhesive member adheres to a surface of said surface protection portion where the surface does not face the second electrode,
• wherein the fluorine-based silane compound having at least one alkoxysilyl group is a compound represented by General Formula (A) below, and a molecular weight of the fluorine-based silane compound having at least one alkoxysilyl group is 1.000 or lower:
• CF3(CH2)q—O(CF2CF2O)m(CF2)p(CH2)nSiR1(3-a)(OR2)a General Formula (A)
• where in the General Formula (A),
• R1 and R2 each independently represent a monovalent hydrocarbon group having carbon atoms of 1 or more but 4 or less,
• a represents an integer of 2 or 3,
• p represents an integer of 1 or 2,
• q represents an integer of 0 or greater but 5 or smaller,
• m represents an integer of 1 or greater but 3 or smaller,
• n represents an integer of 2 or greater but 4 or smaller, and
• p+q+2m+n represents an integer of 5 or greater but 14 or smaller.
