Abstract: Photoelectric conversion elements and electrolyte solutions suitable for various applications and related components, and methods associated therewith, are described. Photoelectric conversion elements may include an electrolyte solution including an ionic liquid and an organic solvent. The ionic liquid may have an electron pair accepting functional group and the organic solvent may have an electron pair donating functional group. In some cases, including specified amounts of certain ionic liquids and organic solvents together may result in an electrolyte solution providing for advantageous photoelectric conversion efficiency while exhibiting low volatility.
