PROBLEM TO BE SOLVED: To further increase an open-circuit voltage.SOLUTION: A dye-sensitized solar cell module 10 includes a plurality of dye-sensitized solar cells 40. Each of the dye-sensitized solar cells 40 includes: an electrode 20 provided with an electron transport layer 24 on a light-transmissive conductive substrate 14; a counter electrode 30 arranged so as to face the electrode 20; an interposed layer 26 interposed between the electrode 20 and the counter electrode 30; and a hole transport layer 28 existing between the interposed layer 26 and the counter electrode 30. The interposed layer 26 contains a porphyrin dye having one or more porphyrin structures, an inorganic salt having a monovalent anion, and a hole transport material.SELECTED DRAWING: Figure 1 【課題】開放電圧をより高める。【解決手段】色素増感型太陽電池モジュール１０は、色素増感型太陽電池４０を複数備えている。この色素増感型太陽電池４０は、電子輸送層２４を光透過導電性基板１４上に備えた電極２０と、電極２０に向かい合うように配置された対極３０と、電極２０と対極３０との間に介在する介在層２６と、介在層２６と対極３０との間に存在するホール輸送層２８とを備えている。介在層２６には、ポルフィリン構造を１つ以上有するポルフィリン色素と、一価のアニオンを有する無機塩と、ホール輸送材料とが含まれている。【選択図】図１
