Researchers from Pennsylvania State University Report Details of New Studies and Findings in the Area of Materials Science (Conductive Upconversion Er,Yb-FTO Nanoparticle Coating To Replace Pt as a Low-Cost and High-Performance Counter ...)

By a News Reporter-Staff News Editor at Journal of Technology -- Researchers detail new data in Materials Science. According to news reporting originating in University Park, Pennsylvania, by VerticalNews journalists, research stated, "F-doped SnO2 (FTO) nanocrystals modified by Er and Yb with upconversion capability and excellent catalytic properties have been designed and fabricated as an economic replacement for Pt for use as the counter electrode (CE) in dye-sensitized solar cells. The cost of the UC-FTO counter electrode is only similar to 1/20th of that for Pt."

The news reporters obtained a quote from the research from Pennsylvania State University, "The upconverted luminescence-mediated energy transfer and the superior catalytic property for circulation overpowered the slight degradation caused by increased CE/electrolyte interface resistance. A 23.9% enhancement in photocurrent was achieved with little degradation in photovoltage, resulting in a 9.12% increase in solar-to-electric power conversion efficiency."

According to the news reporters, the research concluded: "Near-infrared (NIR) light-to-electricity has been directly observed by SPS and IPCE characterizations, showing the effect of the upconversion counter electrode."
