We have succeeded in observation of photoresponsivity of BaSi₂ film grown on Si by vacuum evaporation method, raising its promising application in high efficiency thin film solar cell. Photocurrent was observed at photon energies larger than 1.28 eV which is corresponding to band gap of evaporated BaSi₂ film.
