Evolution of BODIPY Dyes as Potential Sensitizers for Dye-Sensitized Solar Cells

摘要

Enhancement of light-harvesting efficiency (LHE) in the redear-IR (NIR) region (600-1000 nm) of the solar spectrum is a challenge to improvement of the photovoltaic performances of dye-sensitized solar cells (DSSCs). Therefore, design and development of effective red/NIR photosensitizers are currently a hot topic in DSSCs. BODIPY dyes can offer magnificent characteristics such as sharp and moderately strong absorption, large quantum yields, long excited state lifetimes, good solubility and easy chromatographic separation. From this perspective, recent progress in BODIPY-sensitized solar cells is reviewed.
