BODIPY Dyes in Solar Energy

Abstract

Solar energy shows great potential in the future energy market due to its essentially unlimited supply and renewable, cheap, and clean nature. Among the third-generation solar technologies that are able to harvest light and convert it to electricity are dye-sensitized solar cells (DSSCs), organic solar cells (OSCs), and inorganic-organic hybrid solar cells also known as perovskite solar cells (PSCs). Among the various organic dyes, BODIPY (4,4-difluoro-4-bora-3a,4a-diaza-s-indacene) dyes have been recognized as promising candidates for solar cells due to their intrinsic advantages such as sharp and strong absorption near 500 nm, which is leading to efficient light-harvesting capability, diverse modification on the core structure at all positions and with any desired functionality, long excited state lifetimes, excellent photo-stability, and good solubility in organic solvents. This chapter will focuse on studies of BODIPY dyes in solar energy technology.
