Synthesis of (2-(4-methylthiazol-5-yl) ethoxy)-substituted silicon phthalocyanine and novel green silver nanoparticles: DSSC targets

In this study, designed as a dye-sensitive solar cell material which, bis-(2-(4-methylthiazol-5-yl) ethoxy) phthalocyaninato silicon (IV) compound (3) was obtained from the chemical reaction of SiPcCl2 and 4-methyl-5-thiazoleethanol. Silver nanoparticles (AgNPs) were synthesized using environmentally friendly and cost-effective green methods using leaf and flower extracts of Corydalis cava(CoV) and Nonea pulla(NP) plants. For the characterization of phthalocyanine compound and silver nanoparticles, Transmission electron microscopy (TEM), 1H NMR, 13C NMR, X-Ray Diffraction (XRD), UV-visible, FT-IR and Mass spectrum devices were used. The power conversion efficiency of without doping compound 3 is 1.20. After doping this compound with CoVAgNPs and NPAgNPs, the power conversion efficiencies increased to 1.74 and 2.10. From this it is clearly seen that silver nanoparticles are effective. It is concluded that better photovoltaic materials can be created by using phthalocyanine and silver nanoparticles together.
