WebSome researchers use much more stringent criteria such as a cut-off of 0.7 . In some instances, this may not be realistic: for example, when the highest loading a researcher finds in her analysis is 0.5 . Other researchers relax the criteria to the point where they include variables with factor loadings of 0.2 . WebMar 17, 2024 · The efficiency of Cu(In,Ga)(S,Se)2 (CIGSSe) solar cell absorbers can be increased by the optimization of the Ga/In and S/Se gradients throughout the absorber. Analyzing such gradients is therefore an important method in tracking the effectiveness of process variations. To measure compositional gradients in CIGSSe, energy dispersive X … WebCut Points.
