A series of newmetal-freeorganic dyes with either a boron dipyrromethene (BODIPY)-phenylene or -thiophene as a π-conjugated bridge have been synthesized for application in dye-sensitizedsolarcells. The photophysical and electrochemical properties of these dyes were investigated and their performance as sensitizers in dye-sensitizedsolarcells has been measured. The structure–property relationship
