Si-based thin-film solar cells using a semiconducting silicide pn junction

Research Project Outline

We develop a pn junction solar cell using semiconducting BaSi2, which is composed of abundant chemical elements of Si and Ba. Energy conversion efficiencies exceeding 25% will be expected for only a 1um-thick pn junction diode with this material. We focus on the formation technique for a high-quality BaSi2 pn junction, which influences the solar cell performance, and aim to show the potential of this new material as a thin-film solar cell.
