Research Project Outline
Aiming to supply of renewable energy stably at the after next generation, we will improve the performance of rare-metal free thin film photovoltaic (PV) cells. In order to stop the global warming and to spread the PV cells for the low-carbon society, we should aim at both the stable supply of raw material of PV cells and the increase in the conversion efficiency. This project aims to develop a new type PV cell that can be supplied steadily in the market place. This project includes the following three stages: increase in the conversion efficiency of In-free CZTS-based thin film PV cells, development of new materials for PV cells and buffer layer, and development of a new nano-structure for PV cells.
