Study Data from University of Tokyo Update Knowledge of Nanoparticles

June 27, 2014

By a News Reporter-Staff News Editor at Science Letter -- Research findings on Nanoparticles are discussed in a new report. According to news reporting out of Tokyo, Japan, by NewsRx editors, research stated, "Poly-(3,4-ethylenedioxythiophene):poly(styrenesulfonic acid) (PEDOT:PSS)/c-Si heterojunction solar cells are studied with and without gold nanoparticles (AuNPs) incorporation into PEDOT:PSS layer."

Our news journalists obtained a quote from the research from the University of Tokyo, "The results show that the devices with 10-15% AuNPs incorporation achieve an efficiency of 10.28%, an enhancement of about 10% compared with the reference cell without AuNPs incorporation, which exhibits a conversion efficiency of 9.29%. The local surface plasmon resonance (LSPR) originated from incorporated AuNPs is thought to be one of the reasons why the short-circuit current density improves."

According to the news editors, the research concluded: "Meanwhile, the C-V characteristic results suggest that an improvement in built-in potential leads to promote the carrier-collection efficiency, thereby resulting in improved photovoltaic performance."
