    摘要: A method of fabricating a light absorption layer of a photovoltaic cell is disclosed. The method comprises depositing an alloy precursor on a base, the alloy precursor including a Group IB element, for example copper, a first Group IIIB element, for example indium, and a second Group IIIB element, for example gallium, annealing the alloy precursor so as to form an alloy and agitating the alloy precursor or alloy ultrasonically during and/or after annealing. The method may comprise zone annealing the alloy precursor.
