By a News Reporter-Staff News Editor at Energy Weekly News -- Fresh data on Solar Energy are presented in a new report. According to news originating from Buffalo, New York, by VerticalNews correspondents, research stated, "By introducing silver nanoparticles (NPs) and SiO2 spacer layers on top of Si-based Schottky barrier solar cells, we demonstrated a positive and tunable light trapping effect introduced by metallic NPs. A redshift of the surface plasmon resonant wavelength of Ag NPs from 550 nm to 650 nm, corresponding to the optical absorption peak of the solar cell, was observed with an increased average particle diameter from 19.7 nm to 85 nm."
Our news journalists obtained a quote from the research from the State University of New York, "Enhanced light trapping effects at distinct resonance wavelengths were observed in the optical spectra of the plasmonic-enhanced devices. Electrical measurements confirmed the expected photocurrent improvement at these corresponding wavelengths. It was also revealed that the Ag NPs enhance the carrier generation rate inside of the Si active layer without sacrificing carrier collection efficiency of the device."
According to the news editors, the research concluded: "The short-circuit current density of the best cell we obtained in this work was improved from 13.7 mA/cm(2) to 19.7 mA/cm(2), with an enhancement factor of 43.7%."
