With the resource exhaustion and the environmental deterioration, people gradually realize the necessity of developing new clean resource.Solar energy will soon be in great demand since it is inexhaustible and much cleaner than any other conventional energy resources.However, the shortage of multierystalline silicon has restricted the development of solar cells..Hydrometallurgy purification is a method which is operated by leaching in room temperature for silicon purification.The silicon samples were crushed,and carried out in HF solution with ultrasonic.After experiment, the products were filtered,washed with distilled water, vacuum dried, finally analyzed by inductived coupled plasma-atomic emmision spectrometrv(ICP-AES).
