[Analysis Case] Composite Evaluation of Zn-based Buffer Layer Using X-rays
Evaluation of composition, bonding state, structure, and density is possible.
In the pursuit of improving the efficiency of CIGS thin-film solar cells, various buffer layer materials have been investigated for controlling the band structure and crystallinity from the light absorption layer to the transparent electrode. This presents a case study of various evaluations conducted using X-rays on Zn-based buffer layers deposited on a flattened substrate. Comparisons can be made between different levels based on deposition conditions and various processes after deposition.
