Barium disilicide: Development of a novel, low cost and earth abundant absorber material for thin film solar cell applications

In the ongoing search for (new) highly efficient and cheap photovoltaic materials, orthorhombic barium disilicide has sparked recent interest. Studies have shown that BaSi2 exhibits good electrical properties, a bandgap of 1.3 eV and a high absorption coefficient. However, these studies have mainly been performed on molecular beam epitaxially...
