چکیده مقاله:
In recent years, extensive efforts have been made to synthesize and review the organic colors used in solar cells. These color sensors can be divided into two groups of polypyridine ruthenium complexes and metal free organic dyes-sensitized.ruthenium-based paints have had disadvantages, so in recent years, studies have been made on a bunch of dyes-sensitized called metal free organic dyes for use in solar cells, such as triphonylamine, coumarin, squarine, indol, carbazole, perylene-based and others (Fig.1).The results of the study showed that the molecular structure of organic dyes plays a very important role in the efficiency of the conversion of sunlight energy into electrical energy in dye-sensitized solar cells. In fact, an appropriate organic dye used in solar cells should have a range of absorption of its molecules in the visible region, the molecular extinction coefficient is high, so that light is better absorbed, the length of the resonant system is high in dye, and the molecules of dye should not be on the surface of the semiconductor (titanium dioxide) accumulate.(1,2)
