要約
(EN)

PROBLEM TO BE SOLVED: To provide a photoelectric conversion element using a lignin derivative.

SOLUTION: This element has a semiconductor layer sensitized by one or more kinds of lignin derivatives selected from (a) lignophenol derivative obtained by adding and mixing an acid after solvating a lignin containing material with a phenol compound; (b) second-order derivatives obtained by applying a reaction introducing an acetyl group, a carboxyl group, an amide group, a cross-linking group or the like to the lignophenol derivative, or by applying an alkali treatment; (c) a high-order derivative obtained by applying at least two kinds of the introduction reaction or the alkali treatment reaction to the above lignophenol derivative; (d) a cross-linked product of the second-order derivative to which, a second order derivative, selected from the second-order derivatives obtained by the cross-linking group introducing reaction is cross-linked; and (e) a cross-linked product of the high-order derivative to which, a high-order derivative, selected from the high-order derivatives obtained by the cross-linking group introducing reaction is cross-linked; as a thin film electrode.
