摘要
In this paper, we describe a modified anti-reflective (AR) coating to enhance the efficiency of Cu(In1-x Ga-x)Se-2 (CIGS) solar cells. The process is designed using in-situ real time spectroscopic ellipsometry and optical modeling allowing for the optimization of the properties of the AR coating. The optical model developed is based on a transfer matrix as well as accurate measurement of the dielectric function and thickness of each layer in the stack by spectroscopic ellipsometry. We demonstrate the influence of the substrate temperature on the properties of the AR coating, which can provide an increase in the short circuit current density by up to 10%.
