By a News Reporter-Staff News Editor at Electronics Newsweekly -- Current study results on Quantum Dots have been published. According to news originating from Shanghai, People's Republic of China, by VerticalNews correspondents, research stated, "In this work, the quantum dot CuInS2 layer was deposited on TiO2 film using successive ionic layer absorption and reaction (SILAR) method, and then two bithiazole-bridged dyes (BTF and BIB) were sensitized on the CuInS2/TiO2 films to form dye/CuInS2/TiO2 photoanodes for DSSCs."
Our news journalists obtained a quote from the research from the East China University of Science and Technology, "It was found that the quantum dots CuInS2 as an energy barrier layer not only could effectively improve open-circuit voltage (V-oc) of solar cell, but also increase short-circuit photocurrent (J(sc)) compared to the large decrease in.'s,. of ZnO as energy barrier layer. The electrochemical impedance spectroscopy (EIS) measurement showed that the CuInS2 formed a barrier layer to suppress the recombination from injection electron to the electrolyte and improve open-circuit voltage."
According to the news editors, the research concluded: "Finally, the open-circuit voltage increased about 22 and 27 mV for BTF and BTB-/CuInS2/TiO2-based cells, the overall conversion efficiencies also reached to 7.20% and 6.74%, respectively."
