New Photoelectrochemicals Study Findings Have Been Reported from Pohang University of Science and Technology (POSTECH) (Quantum dot-sensitized mesoporous spherical TiO2 paste with cyclic calcination for photoelectrochemical cells)

By a News Reporter-Staff News Editor at Biotech Week -- Data detailed on Biotechnology have been presented. According to news reporting out of Pohang, South Korea, by NewsRx editors, research stated, "Quantum dot (QD)-sensitized mesoporous (MS) spherical TiO2 paste on fluorine-doped tin oxide was sintered via cyclic calcination (CC), a process of repeating sintering and cooling. This enabled simplification of the sensitization process and yielded uniform, high-quality photoanodes."

Our news journalists obtained a quote from the research from the Pohang University of Science and Technology (POSTECH), "The CdS and CdSe QD-sensitized MS TiO2 cells prepared by the proposed CC process showed short-circuit photocurrents (J(sc)) of 1.3 and 1.5 mA cm(-2), respectively. These Jsc values are several times higher than the values reported for other QD/TiO2 hybrid systems."

According to the news editors, the research concluded: "We believe that this chemical and structural methodology will accelerate the commercialization of quantum dot-sensitized solar cells (QDSCs)."
