在本研究中,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 acid,簡稱PTA),被用來做為奈米級二氧化鈦之間及奈米級二氧化鈦 (TiO2) 與摻氟二氧化錫玻璃 (FTO glass) 基板的連結劑。 在低溫漿料部分,我們使用市售的奈米級二氧化鈦粉末 (PT-501A及P90),開發出一種低溫製作漿料的程序,適用於可撓曲的染料敏化太陽能電池 (dye-sensitized solar cells)。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。 在高溫漿料部分,我們使用溶液凝膠法 (sol-gel) 來製備高溫漿料,輔以PTA乙醇溶液做FTO玻璃基板之間的前處理,再將高溫漿料網印於上,最後封裝製程太陽能電池。
In this study, We use titanium isopropoxide (TTIP) and hydrogen peroxide (H2O2) to prepare a gel (peroxy titanate peroxotitanic acid, PTA). The gel was used as a binder between nanoscale titanium dioxide and nano-level between FTO glass substrate titanium dioxide. In the part of low temperature paste, we use a commercially available nano-titanium dioxide (TiO2) powder (PT-501A and P90) developed a low-temperature slurry production process apply to be fexiable of dye sensitized solar cells (dye-sensitized solar cells). Then use the doctor-blade coating method of titanium dioxide film on glass and plastic substrate with conductive features. Finally, made into a solar cells. In the part of high temperature paste, we use the sol-gel process to prepare a high temperature TiO2 slurry. The solution of PTA in ethanol was sprayed between the FTO glass substrate and the nanoscale titanium dioxide as a pretreatment film. Then the slurry was screen printed above the pretreatment film on the FTO glass substrate. Finally, made into a solar cells.
