Project Details


Photoelectrochemical (PEC) reaction is the important research field in recent years. The hydrogen production from the water or sea water using solar energy and photo-electrodes will be the ultimate goal for clean energy society. However, the lifetime of the photocatalyst and the cost of materials limit their industrial applications. The materials developments and preparations, the optimization of post-annealing process and the simple method for the large area deposition have to be taken into consideration. Therefore, we propose this project in order to design a high efficiency photochemical device. The subjects of this project are the preparation of photocatalytic thin films, and the analysis of PEC response of the samples. This study include the preparation of Ag-Sn-S/Ag-Zn-Sn-S and Ag-Sn-S/Se/Ag-Zn-Sn-S/Se thin films using non-vacuum method, experimental measurements of phase and physical properties for the thin film and the simulation of possible annealing process using the basic concepts of transport phenomena and unit operation. Finally, the photoelectrochemical response of samples in aqueous solution will be realized. This project is consisted of fundamental investigations of materials synthesis, theoretical analysis, and design of the photochemical modulus. We believe that our approach can be the cornerstone of developing high efficiency photochemical reactor for photoelectrochemical applications.
