Abstract: A photovoltaic device and its method of manufacture are disclosed. The device is formed by forming a window layer over a substrate, forming an absorber layer over the window layer, and annealing the absorber layer using a laser beam to remove contaminants from the surface of the absorber layer and/or to reduce the thickness of the absorber layer.
