种SiWNi杂多酸修饰染料敏化太阳能电池光阴极的制备方法。本发明涉及种SiWNi杂多酸修饰染料敏化太阳能电池光阴极的制备方法。本发明是为了解决现有材料制备的染料敏化太阳能电池对电极成本高和光生载流子的复合造成的电池效率低的问题。方法：、合成杂多酸SiWNi。二、制备光阴极(将SiWNi与乙基纤维素、松节油透醇、乙醇混合均匀，丝网印刷成膜)，采用丝网印刷法制成层膜，再将铂浆料丝网印刷两层到杂多酸上，然后高温煅烧。本发明应用于太阳能电池光阴极材料制备领域。 The invention relates to a preparation method of a SiW11Ni heteropoly acid modified dye-sensitized solar cell photocathode, and aims to solve the problems that a dye-sensitized solar cell prepared by existing materials is high in electrode cost and the cell efficiency is low caused by recombination of photon-generated carriers. The method comprises the steps of: firstly, synthetizing heteropoly acid SiW11Ni; and secondly, preparing the photocathode (by mixing SiW11Ni with ethyl cellulose, terpineol and ethanol uniformly and carrying out silk-screen printing to form a film), adopting a silk-screen printing method to form a layer of film, then carrying out silk-screen printing on platinum slurry to form two layers on the heteropoly acid, and then carrying out high-temperature calcining.
