High Performance Dye-Sensitized Solar Cells with Record Open Circuit Voltage using Tin Oxide Nanoflowers Developed by Electrospinning

Flower shaped nanostructures of an architypical transparent conducting oxide, SnO2, have been synthesized by an electrospinning technique for the first time by precisely controlling the precursor concentration in a polymeric solution. The flowers were made up of nanofibrils of diameter [similar]70–1...
