| Abstract: | Orthorhombic barium disilicide （BaSi2） is a novel semiconductor material which has low thermal conductivity, targe absorption coefficient and suitable band gap, it is considered to be a potential solar cell material, and can be widely used. Or thorhombic BaSi2 was reviewed in detail from its crystal structure to electrical properties in the paper, and then, the research progress in thermoelectric properties of BaSi2 in recent years was overviewed. Finally, the problems existing in current research and the research trends of BaSi2 were discussed briefly. |
