|摘要:||The present invention provides a method for manufacturing platinum nanoparticle solution and a self-assembled platinum counter electrode thereof. The present invention adopts a polyol reduction method and controls the reduction reaction periods under various pH conditions. After the platinum nanoparticle dispersion solution of uniformly distributed platinum nanoparticles having small sizes is produced, the self-assembled platinum nanoparticles are adsorbed on a functionalized surface of a conductive substrate by dip coating at the normal temperature. Therefore, the structure of a platinum nanoparticle monolayer is formed, to obtain the self-assembled platinum counter electrode with a homogeneous single layer on the surface. This process is much simpler without adding any stabilizers or surfactants, without involving any subsequent heat treatments, and it consumes less amount of the platinum material. By employing the present invention for commercialization, the cost of mass production for the dye-sensitized solar cell application is thus reduced.|
