低溫製備軟性敏化太陽能電池TiO2電極
Low Temperature Fabrication of TiO2 Electrodes for Soft Dye-sensitized Solar Cells
摘要
1993年瑞士科學家 Gräetzel 教授及其團隊，以低價位光伏電池為主軸概念發展出染料敏化太陽能電池(DSSC)，研究顯示其轉換效率可以達到10.5%。 一般染料敏化太陽能電池電極所使用的都是將透明導電氧化物塗層於玻璃基板上，其透明導電氧化物在玻璃基板上具有良好的光電特性，並且可用於高溫的生產製程，但是無法連續式生產；軟性可塑性基板則可適用於連續性(roll-to-roll)生產的製程，對於大量生產薄膜太陽能電池是很有前景的。本研究中使用低溫製備二氧化鈦薄膜電極於ITO/PET軟性基板上。將所製備的奈米二氧化鈦(TiO2)薄膜電分別以電子掃描式顯微鏡(SEM)、原子力顯微鏡(AFM)及等儀器鑑定表面結構及分析其性質，於100mW/cm2(AM1.5)光照強度條件下所測得最高轉換效率為1.73%。

Dye sensitized solar cell (DSSC) are low cost concept for photovoltaic devices originally proposed by Prof. Gräetzel, and his group who demonstrated a promising 10.5% power conversion efficiency in 1993. Transparent conducting oxide (TCO) coated glass substrate has been the standard choice for the substrate material of the DSSC. It is excellent optical, electrical and encapsulation barrier properties, and compatibility with high-temperature processing. Plastic substrates are also a prerequisite for roll-to-roll production techniques that are considered promising for cost-effective mass production of thin film solar cells. In this study use Low- temperature compressing technique preparation the TiO2 electrodes on ITO-PET plastic substrates. The TiO2 electrodes thin film was inspected with SEM, AFM and BET to analyze surface property. An energy efficiency of 1.73% was achieved at the standard of 100mW/cm2 lighet intensity with AM1.5 spectrum.
