摘要
在典型的染料敏化太阳能电池中,基于铂金属的对电极用于收集外电路的电子,并催化氧化态电解质还原。然而,由于铂金属为贵金属,因此需要开发廉价材料的对电极,从而降低生产成本。低温沉积法是一种简单的制备方法,它的主要优点是,在不需要高温加热的条件下,可以直接在导电衬底上沉积,制备出拥有优异催化性能的硫化镍薄膜,然后直接用作染料敏化太阳能电池的对电极。结果显示,基于硫化镍薄膜对电极的染料敏化太阳能电池的最佳光电转换效率为6.12%,这与基于铂对电极的染料敏化太阳能电池的转换效率(6.16%)非常接近。上述实验结果表明低温沉积法制备的硫化镍薄膜具有优异的电催化性能,有利于染料敏化太阳能电池的光伏性能提升。
In a typical dye-sensitized solar cell,a platinum-based counter electrode is used to collect electrons from the external circuit and catalyze the reduction of the oxidized state electrolyte.However,because platinum is a precious metal,it is necessary to develop in-expensive materials for counter electrodes to reduce production costs.The low temperature deposition technique is a simple preparation method,and its main advantage is that it can be direct deposited on the conductive substrate without high temperature heating to prepare the nickel sulfide film with excellent catalytic performance,and then direct used as the counter electrode of dye-sensitized solar cells.The results indicate that the optimal photoelectric conversion efficiency of dye-sensitized solar cells based on nickel sulfide counter elec-trode reaches 6.12%,which is very close to that of dye-sensitized solar cells based on platinum counter electrode(6.16%).This makes the nickel sulfide counter electrode a competitive alternative to the platinum counter electrode.Therefore,this experiment also provides a method for the preparation of cheap and efficient counter electrodes for dye-sensitized solar cells.
