Dye-sensitized solar cells (DSSCs) have developed rapidly by many research groups because of their various advantages, such as high efficiency and low-cost devices for solar cells. Mainly DSSCs can divide with two parts, inorganic dyes and organic dyes. Inorganic dyes have been studied a lot and it gave also good results. For example Ru-polypyridyl-complex dyes, such as cis-dithiocy-anato bis(4,4`-dicarboxy-2,2`-bipyridine)ruthenium(II) (called N3 dye) can produce solar energy-to electricity conversion efficiency (è) of up to 11% under AM 1.5 G irradiation. Besides N3 dyes, metal-free organic dyes have been utilized in DSSCs because of their wide variety of the structures, facile modification, and high molar absorption coefficient. In this work we have designed and synthesized simple metal-free organic dyes for DSSCs and also have identified their photovoltaic properties.
