摘要： A photocurrent-generating electrode includes a supporting substrate, a first nanoparticle layer, a second nanoparticle layer, and a semiconductor nanostructure formed on the second nanoparticle layer and having a biocompatible semiconductor nanomaterial. The first nanoparticle layer has first noble metal nanoparticles bonded to the supporting substrate. The second nanoparticle layer is formed on the first nanoparticle layer, and has second noble metal nanoparticles having an average dimension larger than an average dimension of the first noble metal nanoparticles. Two adjacent ones of the second noble metal nanoparticles are electrically connected to each other through one of the first noble metal nanoparticles.
