BODIPY, abbreviation for boron-dipyrromethene, is a class of fluorescent dyes. They exhibit several unique characteristics including tunable spectral coverage, high absorption capability, exceptional chemical and photo-resistance in solution and in solid state, very good solubility in organic solvents, and easy structural modification making them attractive for many applications. However, in the past thirty years, the research on BODIPY dyes is heavily focused on development of new molecules for imaging and labeling of biological substrates, and only a few reports are related to solar energy conversion. In this talk, I will  present our recent studies on several functionalized BODIPY dyes with a donor-π-acceptor configuration for dye-sensitized solar cells. Those highly functionalized BODIPY dyes exhibit strong absorption in the visible region and very interesting photovoltaic and sensitization behaviors. Synthesis, single-crystal structures, photophysical and photovoltaic properties will be discussed. The findings from our study will be of great interests to researchers who are working in the fields of solar energy conversion.
