二氧化鈦奈米球應用於染料敏化太陽能電池的探討
Investigation of Applying nano- TiO2 spherical particles on Dye-Senstized solar cells
摘要
本研究探討染料敏化太陽能電池中奈米二氧化鈦電極元件之的設計與製作。首先利用溶膠凝膠法，製備出均一粒徑為的二氧化鈦奈米球。元件的製作是利用商用二氧化鈦粉末與二氧化鈦溶凝膠互搭配設計製作出不同的電極元件分別為1. P25(TiO2)；2. 元件(一):TiO2 particles(172、200、260 nm)；3. 元件(二):P25(TiO2)/ TiO2 particles(172、200、260 nm) / P25(TiO2)。先將電極元件作光電分析，最後組裝成電池，可以測定入射光電轉化效率(IPCE)及總效率。實驗結果顯示雖然元件(一)的染料吸附性不好，但fill factor 值很高。另外元件(一)比P25電極有較高的透光率。

The design and fabricate of TiO2 particle electrode devices used in the dye-sensitized solar cells. Different particle sizes of monodispersed TiO2 particle were first prepared using a sol-gel methed. Each layer of the TiO2 films was produced using either commercial powers, P25, or the prepared sol-gel solution , a nano-TiO2 electrode device of P25, ano-TiO2 spherical particles, 25 / nano-TiO2 spherical particles / P25, respectively. The optoelectronic characteristics of the electrode was by current-voltage (I-V) and UV-Visible spectrometry measurements. Results show that the fill factor of the solar cells with the TiO2 particle electrode has higher value. In addition, he TiO2 particle electrode film demonstrated a higher transparency than P25 electrode.
