When considering the polycrystalline nature of the CIGS and CZTS thin-films, those efficiencies are surprisingly high. For further enhancement of the efficiency it is important to understand how the microstructure affects the electrical properties of the absorber films and, hence, the device performance. Therefore, as one part, one needs to study the relationship between structural and chemical properties of grain boundaries (GB).
