【Abstract】 Multi-element evaporation process is considered as the most suitable technique for high performance Cu(In,Ga)Se2thin film solar cells. It was because that CIGS films deposited by this process has many advantages, such as high quality films with large grains and smooth surface, appropriate band gap grading and controlling the composition of CIGS films exactly. All these issues are correlated to the efficiency of solar cells. Currently the world record efficiency of CIGS solar cell based on the evaporation process has exceeded of 20%. However, the new research focus is still the optimization of the evaporation process for higher performance solar cells, flexible solar cells and the commercial manufacturing of CIGS modules. The current research progress of CIGS solar cells and modules based on the evaporation technique were introduced.更多还原
