Suspension of electron-hole recombination in a dye-sensitized solar cell through simultaneous optimization of micro and electronic structures

This study sought to optimize the structures in a working electrode at the micro- as well as electron-scales with the aim of suspending electron-hole recombination in order to increase the power conversion efficiency of dye-sensitized solar cells (DSSCs). The structure of DSSC was optimized from the micro-scale (multilayered TiO2) to the electron-scale (orbital hybridization of TiO2).132
