Abstract: Five new dyes with D–π–A structure bearing 5-(methylene)-rhodanine-3-acetic acid as an acceptor-anchoring part and thieno[3,2-b]indole or benzo[g]thieno[3,2-b]indole as an electron-donating part were synthesized and applied as photosensitizers for dye-sensitized solar cells (DSSCs). In addition, thermal stability, optical and electrochemical properties of these dyes were investigated. The highest PCE value of 1.09% (Jsc = 3.01 mA cm–2, Voc = 0.53 V, FF = 0.69) was achieved for DSSC based on benzo[g]thieno[3,2-b]indole dye under AM 1.5G irradiation.

Keywords: thieno[32-b]indoles, rhodanine-3-acetic acid, metal-free dyes, D–π–A structure, dye-sensitized solar cells.
