Outline of Final Research Achievements

Synthesis of semiconductor nanoparticles with sustainability and tuning of their crystalline and surface structure are required for the realization of a novel quantum dot sensitized solar cell. In this study, we demonstrate the novel synthesis method of Ag/chalcopyrite composite nanoparticles. Ag metal part of Ag/chalcopyrite composite nanoparticles serves as a functional group of a surfactant molecule. Therefore, Ag-semiconductor composite nanoparticles are considered to adhere through the Ag side to the oxide surface to form chalcopyrite/Ag/oxide heteronanostructures. Furthermore, this structure may enhance the electron transport between the semiconductor nanoparticle and oxide and prevent electron-hole recombination at the interface. And also, Ag metal part leads to the local enhancement of electric field. Furthermore, our synthesis method enables us to fabricate Ag/AgCuS/CuInS2 composite nanoparticles.
