Barium disilicide (BaSi₂) is an intermetallic semiconductor compound belonging to the alkaline-earth silicide family, characterized by a hexagonal crystal structure. While primarily a research material rather than a widespread commercial product, BaSi₂ has attracted significant attention in photovoltaic and thermoelectric applications due to its narrow bandgap and potential for efficient solar energy conversion. Its potential advantages over conventional semiconductors stem from earth-abundant constituent elements and favorable optical properties for solar spectrum absorption, making it a candidate for next-generation thin-film solar cells and energy harvesting devices, though production and performance optimization remain active areas of investigation.
