A manufacturing process of the optical incidence side electrode of a dye sensitizing type photoelectric conversion element

Japanese Patent JP6269923

B2

PROBLEM TO BE SOLVED: To provide a method of manufacturing a light incident side electrode of a dye-sensitized photoelectric conversion element at a low cost and with stability.SOLUTION: A plurality of semiconductor fine particle groups having different average grain diameters are prepared (S1). Each of the plurality of semiconductor fine particle groups is individually mixed in dispersion media to form a plurality of colloids (S2). A pair of electrodes one of which consists of a transparent substrate having a transparent conductive film are inserted into the colloid of the semiconductor fine particle group having the minimum average grain diameter, and a current is applied between the electrodes to perform electrophoresis (S3). During the electrophoresis, the colloids of the remaining semiconductor fine particle groups are added by a predetermined amount at a predetermined time interval, in an ascending order of the average grain diameter, and thereby, semiconductor fine particles are laminated on the transparent conductive film of the transparent substrate (S4). The transparent substrate on which the semiconductor fine particles are laminated is subjected to heat treatment (S5). A semiconductor fine particle layer on the transparent substrate is made adsorb dye (S6).
