Characterization and Analysis of Ultrathin CIGS Films and Solar Cells Deposited by 3-Stage Process

Figure 7

Simulated results on the effect of CIGS absorber layer thickness on the short-circuit current density (), open-circuit voltage (), fill factor (FF), and the efficiency for a fixed defect density of 5 × 10¹¹ cm⁻³ (the blue dots indicate measured values).
