A method and an apparatus for compacting a CIGS thin film in a non-vacuum environment are provided. According to the present invention, a substrate having a CIGS light absorbing layer configured thereon is processed with a soft baking process. Then, a pneumatic cylinder is employed for providing a pressure for driving a roller which is fixed to a holder. The holder is connected to the pneumatic cylinder. The roller is driven to downwardly apply a pressing force onto the CIGS light absorbing layer. The substrate is then moved back and forth to compact the CIGS light absorbing layer uniformly.
