Disclosed is a method for manufacturing a photovoltaic device including: a forming the first sub-layer including impurity by allowing first flow rate values of the source gas introduced into one group of a first group consisting of odd numbered process chambers and a second group consisting of even numbered process chambers to be maintained constant in each of the process chambers of the one group; and a forming the second sub-layer including impurity by allowing second flow rate values of the source gas introduced into the other group of the first group and the second group to be maintained constant in each of the process chambers of the other group, wherein the second flow rate values are less than the first flow rate values.
