NOVELTY - A silicon melt solution is discharged as granules from a nozzle portion (1a) and dropped into a crucible (1). The granular silicon melt solution (4) is cooled and solidified, to obtain crystalline-silicon particles (5). After supplying the silicon raw material to the storage apparatus (7), pressure inside the storage apparatus is reduced to atmospheric pressure or below. The inert gas inside the storage apparatus is pressurized to inert-gas pressure inside crucible, while introducing inert gas to decrease oxygen concentration.    USE - Manufacture of crystalline-silicon particles for photoelectric conversion apparatuses, such as solar cells.    ADVANTAGE - The method enables economical and continuous manufacture of high-quality crystalline-silicon particles having excellent chemical stability, with high productivity and without impurities.    DETAILED DESCRIPTION - A silicon melt solution is discharged as granules from a nozzle portion (1a) and dropped into a crucible (1) of a melting-fall production apparatus (20). The granular silicon melt solution (4) is cooled and solidified during dropping, to obtain crystalline-silicon particles (5). The internal atmosphere consists of inert gas at a pressure higher than atmospheric pressure. The silicon material providing apparatus (30) has a storage apparatus (7) which stores and supplies raw material to the crucible. After supplying the silicon raw material to the storage apparatus, pressure inside the storage apparatus is reduced to atmospheric pressure or below. The inert gas inside the storage apparatus is pressurized to the inert-gas pressure inside the crucible, while introducing an inert gas into the storage apparatus and decreasing the oxygen concentration in the storage apparatus. An INDEPENDENT CLAIM is included for production apparatus of crystalline-silicon particles.
