说明

二氧化钛浆料,反射器是二氧化钛的前体,在氟掺杂的氧化锡 (FTO) 基板上形成中孔光散射层。它用于各种电化学设备中,以提高电子迁移率和功率效率。

光散射二氧化钛浆料可以涂在二氧化钛的主要透明层上,形成双层钛膜。它可用作染料敏化太阳能电池(DSSC)的负极。
散射反射器二氧化钛膏可与透明二氧化钛膏一起使用,以在不需要透明度的应用中增强 DSSC 性能。
散射二氧化钛膏含有高度分散的锐钛矿散射粒子(150nm 至 250nm)。这种浆料在应用到预先印刷的活性层上时会产生非活性散射层。
干燥后;该浆料必须与预印的活性层一起在 500°C 或以上温度下烧制。这会产生不透明的烧结层;一个印刷层的厚度约为3μm;使用 90T 网筛时。

一般描述

Titania paste, the reflector is a precursor for titania, that forms a mesoporous light scattering layer on the fluorine doped tin oxide (FTO) substrates. It is used in a variety of electrochemical devices to improve electron mobility and power efficiency.
 

应用

Light scattering titania paste can be coated on the primary transparent layer of TiO2 to form a bilayered titanium film. It can be used as a negative electrode for dye sensitized solar cells (DSSCs).
Scattering Reflector Titania Paste can be used in conjunction with Transparent Titania Paste for enhanced DSSC performance in applications where transparency is not required.
Scattering Titania Paste contains highly dispersed anatase scattering particles (150nm to 250nm). This paste produces a non-active scattering layer when applied onto a pre-printed active layer.
After drying; this paste must be fired – together with the pre-printed active layers – at or above 500°C. This results in an opaque sintered layer; with a thickness of ~3μm for one printed layer; when using a 90T mesh screen.

Storage: Store in the dark at 20°C
