Liquid composition, photoelectric conversion element production method, and photoelectric conversion element

A photoelectric conversion element provided with a quantum dot layer between a first electrode and a second electrode disposed above the first electrode, the photoelectric conversion element comprising:

• an underlayer;
• and
• the quantum dot layer formed on the underlayer,
• wherein the underlayer supplies electrons or positive holes to the quantum dot layer;
• the quantum dot layer comprises quantum dot particles and a surface protection material protecting a surface of the quantum dot particles;
• the surface protection material contains, as a main component, a surface modification compound comprising:
• a functional group having a heteroatom, and a chain-type saturated hydrocarbon group represented by the molecular formula CnH2n+1 (n being a natural number);
• and
• an absolute value of a difference between a surface free energy of the quantum dot layer and a surface free energy of the underlayer is 5 mN/m or less.
