Dye-sensitized solar cells (DSSCs) have been studied extensively in consequence of their simple synthesis, and moderate to high power conversion efficiencies (PCEs). Many sensitizers have been studied with excellent PCEs. In this work, three new porphyrin dyes XW45–XW47 have been synthesized employing a dialkoxy-wrapped phenothiazine donor, a tetraalkoxy-wrapped porphyrin π-framework, a benzothiadiazole (BTD)-based auxiliary acceptor, and an anchoring benzoic acid group. High efficiencies of 10.32, 11.38 and 10.90% were achieved for the cosensitized solar cells based on XW45–XW47, respectively. In addition, a high efficiency of 13.08% was achieved under 30% full sun illumination. These results indicate that the cosensitization of efficient porphyrin dyes containing a wrapped donor, a wrapped porphyrin framework and a properly substituted auxiliary electron accepting benzothiadiazole unit provides an effective approach for developing efficient DSSCs which may be applicable under both outdoor and indoor conditions (see the article by Yunyue Lu, Yingchun Cheng, Chengjie Li, Jiaxin Luo, Weiqiang Tang, Shuangliang Zhao, Qingyun Liu & Yongshu Xie on pages 994–1000).
