Development of Microtextured Mold and Its Application

Mold Fabrication by Vibration Assisted Cutting and Its Application to Transparent Electrode

Abstract

Improving materials surface function by introducing microtextures is of great interest in various fields. A part of the authors also has performed to improve the surface functions of photocatalyst by introducing the microcutting textures, and has confirmed an improvement in its hydrophilicity. In this report, a mold for microtextures transcription was performed using the combination of the vibration assisted microcutting and the anodic oxidation in order to achieve more complicated surface microtextures. Also, a transparent resin electrode with microtextures duplicated using the fabricated mold, was also fabricated. And, its performance was evaluated by applying it to the dye-sensitized solar cell. As a result, some improvement was observed in the electric power generating efficiency of the fabricated solar cells.
