New Materials Science Study Findings Recently Were Reported by Researchers at University of Salento

June 3, 2014



By a News Reporter-Staff News Editor at Journal of Technology -- Investigators publish new report on Materials Science. According to news originating from Lecce, Italy, by VerticalNews correspondents, research stated, "In this work, we report on similar to 4% power conversion efficiency (PCE) depleted bulk heterojunction (DBH) solar cells based on a high-quality electrode with a three-dimensional nanoscale architecture purposely designed so as to maximize light absorption and charge collection. The newly conceived architecture comprises a mesoporous electron-collecting film made of networked anisotropic metal-oxide nanostructures, which accommodates visible-to-infrared light harvesting quantum dots within the recessed regions of its volume."

Our news journalists obtained a quote from the research from the University of Salento, "The three-dimensional electrodes were self-assembled by spin-coating a solution of colloidal branched anatase TiO2 NCs (BNC), followed by photocatalytic removal of the native organic capping from their surface by a mild UV-light treatment and filling with small PbS NCs via infiltration. The PCE similar to 4% of our TiO2 BNC/PbS QD DBH solar cell features an enhancement of 84% over the performance obtained for a planar device fabricated under the same conditions."

According to the news editors, the research concluded: "Overall, the DBH device fabrication procedure is entirely carried out under mild processing conditions at room temperature, thus holding promise for low-cost and large-scale manufacturing."
