摘要

在本研究中，我們使用市售的奈米級二氧化鈦TiO2粉末（P25以及P90），開發出一種低溫製作漿料的程序，適用於可繞曲的染料敏化太陽能電池（dye-sensitized solar cells）當中。我們使用異丙醇鈦（titanium isopropoxide, TTIP）與過氧化氫(H2O2)製備一種凝膠(過氧鈦酸peroxotitanic，簡稱PTA)，被用來做為奈米級二氧化鈦之間的連結劑。最後使用doctor-blade 的塗佈法將二氧化鈦成膜在具有導電功能的玻璃基板與塑膠基板上，最後封裝製作成太陽能電池。
在模擬100mW/cm2的太陽光前提下，最佳化條件的低溫TiO2漿料用在硬式基板(FTO/ITO基板)的太陽能電池上，可以得到轉化率達到約4.68%。改用在軟式基板(PEN塑膠基板)的太陽能電池上，可以得到轉化率達到3.10%。

In this paper, we have developed a low temperature process for the flexible dye-sensitized solar cells (DSSCs) using commercially available TiO2 nanoparticles (P25 and P90). The connection between TiO2 nanoparticles was achieved by a low-temperature sol-gel processing of titanium isopropoxide (TTIP) and H2O2. TiO2 film was formed on a conductive indium-tin oxide ITO-coated polyethylene naphthalate (PEN) plastic sheet by the doctor-blade coating. A binder-free paste consisting of the sol-gel derived nanocrystalline TiO2 as the interparticle binding agent served as a connection media among P25/P90 particles. TiO2-coated ITO-PEN electrodes were dye-sensitized with Ru-based bipyridyl complexes to construct the photoanodes for the plastic dye-sensitized solar cells. A flexible solar cell with optimized TiO2 paste and Solar-to-electric energy conversion efficiencies of 4.68 and 3.10% have been achieved for cells with conductive glass and plastic film substrates, respectively, under illumination with AM 1.5 (100m W/cm2) simulated sunlight.
