CIS films were grown on soda-lime glass/Mo substrates using a low cost, non-vacuum technique. Morphology of the resulting layers was improved and solar cells with 12.4% total area efficiency were demonstrated on these films. A submodule of about 25 cm2 area was also fabricated with a conversion efficiency of 8.17%. Work is now in progress to grow films containing Ga and/or S and to take this technology to larger scale production.
