摘要：
In this study, we demonstrate a new approach to rapidly prepare Cu (In,Ga)Se2 (CIGS) absorbing layer through combining the ball milling with evaporation processes. This allows for the rapid preparation of CIGS film precursors in 90 s, while also achieving arbitrary proportion doping, which significantly increases process efficiency. CIGS thin films with a consistent surface composition were produced using this technique, and the changes on how doping with sodium (Na) affected the growth and surface shape of the films were investigated. As a result, 7.7 % efficient solar cells were fabricated, laying the groundwork for the future rapid acquisition of highefficiency solar cells.
