胶体二氧化钛薄膜已制备使用无粘结剂的水性浆料与德固赛P25和六氟钛酸(H2 TiF 6),这是优化不同的基板。使用该浆料制造的染料敏化太阳能电池(DSSC)在(约393 K)下烧结,并且对于使用钛箔(约1 mm厚)、在聚对苯二甲酸乙二醇酯(ITO-PET)上的铟掺杂氧化锡的器件以及对于在氟掺杂氧化锡(FTO)玻璃基板上的共敏化器件,测量的效率(η)分别为3.0、4.2和6.1%。电化学阻抗测量结果表明,在低烧结温度(约393 K)下制造的设备的电荷传输电阻是不太一致的比较,在773 K烧结的设备。这些测量与低温烧结DSSC器件的器件效率(η)的增加的变化相关。
Colloidal TiO2films have been prepared using a binder-free aqueous paste with Degussa P25 and hexafluorotitanic acid (H2TiF6), which was optimised for different substrates. Dye-sensitized solar cells (DSSC) fabricated using this paste were sintered at (ca.393 K) and efficiencies (η) of 3.0, 4.2 and 6.1% were measured for devices using titanium foil (ca.1 mm thickness), indium-doped tin oxide on polyethylene terephthalate (ITO-PET), and for co-sensitized devices on fluorine-doped tin oxide (FTO) glass substrates, respectively. Electrochemical impedance measurements show that the charge transport resistance is less consistent for devices fabricated at low sintering temperature (ca.393 K) by comparison to devices sintered at 773 K. These measurements correlate with the increased variation in device efficiency (η) for low temperature sintered DSSC devices.
