A low-temperature type organic molten salt that has a molten liquid form at room temperature, is hardly volatile, has excellent safety and durability, and has high ionic conductivity. A photoelectric conversion element and a photovoltaic cell are provided. The present invention includes at least two organic salts consisting of a nitrogen-containing heterocyclic cation into which an alkyl group having 3 or less carbon atoms is introduced and an anion corresponding to the nitrogen-containing heterocyclic cation, and all the organic salts have the same anion species. In this case, at least one of the organic salts is a low-temperature type organic molten salt that is solid at a temperature of 70 ° C., a photoelectric conversion element having a charge transport layer made of the organic molten salt, and a photovoltaic cell using the photoelectric conversion element.
