Synthesis of Silver Nanoparticles Formed by Chaerophyllum Macrospermum and Eremurus Spectabilis Biomaterial and Investigation of Photovoltaic Parameters by Adding Silicon Phthalocyanine

Abstract

Silver nanoparticles (AgNPs) were obtained by green synthesis using Chaerophyllum macrospermum (CM) and Eremurus spectabilis (ES). These particles were characterized by TEM, XRD, IR, UV, mass, and NMR spectra. TEM images show that the mean particle size of CM-AgNPs was 30 nm and the diameter of ES-AgNPs was 14.2 nm. XRD measurements showed that CM-AgNPs were 30.85 nm and ES-AgNPs 18.80 nm in a perfect face-centered cubic crystal structure. CM-AgNP showed maximum absorption at 453 nm and ES-AgNP at 455 nm; AgNPs exhibited a strong surface plasmon resonance (SPR) and played a role in stabilization. A silicon phthalocyanine compound was synthesized and characterized. The photovoltaic properties of the axial phthalocyanine compound with and without doping of Chaerophyllum macrospermum and Eremurus spectabilis silver nanoparticles were investigated. Better dye-sensitive solar cells were formed by doping silver nanoparticles to phthalocyanine compounds with an increase in the percentage of energy conversion efficiency by 0.26 with ESAgNP doping and 0.76 with CMAgNP doping.
