本實驗使用網版印刷法製作工作電極與散射層。工作電極使用P25-TiO2，散射層使用P200-TiO2，得到最佳工作電極參數後搭配後處理再以4種硒化鎳對電極與Pt對電極進行比較。

以水熱法合成四種硒化鎳化合物，包含Ni0.85Se、Ni0.85Se/RGO、NiSe2、NiSe2/RGO，並研究添加石墨烯後對電極的催化活性、電荷轉移電阻的差異，期望提高染料敏化太陽能電池效率，取代傳統Pt對電極。

自製硒化鎳化合物呈奈米結構，提供許多活性位置，添加石墨烯具協同效應促進催化能力，降低電荷轉移電阻。

In this experiment, a working electrode and a scattering layer were preparation by screen printing method. P25-TiO2 was used for the working electrode, P200-TiO2 was used for the scattering layer, and find the best working electrode parameters. After the TiCl4 treatment, compared four nickel selenide counter electrodes with Pt counter electrode .

Four kinds of nickel selenide compounds were synthesized by hydrothermal method, including Ni0.85Se, Ni0.85Se/RGO, NiSe2, NiSe2/RGO, catalytic activity and charge transfer resistance of the counter electrode after adding graphene were studied. Expect to improve sensitized solar cell efficiency and replacing traditional Pt counter electrodes.

Homemade nickel selenide compound has a nanostructure and provides many active sites. The addition of graphene has a synergistic effect to promote the catalytic ability and reduce the charge transfer resistance.
