Abstract

Cu(In,Ga)Se2 (CIGS) thin films were grown using a MBE apparatus equipped with a RF-cracked Se-radical beam source that meets the technical challenges of high quality CIGS film growth, efficient use of Se source material, and precise control of growth conditions and material properties. A unique combination of film properties: a highly dense and smooth surface, large grain size is shown. A competitive energy conversion efficiency of 17 % has been demonstrated from a solar cell fabricated using a CIGS absorber grown with a Se-radical source. In addition to the unique combination of film properties and high photovoltaic performance, a significant improvement in the use of Se source material in comparison with the conventional Seevaporative sources has been demonstrated.
