Composition ratios such as Cu/(In+Ga) and Ga/In have a great influence not only on performances but on yields of Cu(In,Ga)Se 2 (CIGS) solar modules. We demonstrated on a composition monitoring of a Cu/(In+Ga) ratio and control of a Ga/In profile in t

Improved preparation process of a device quality Cu(In,Ga)Se 2 (CIGS) thin film was proposed for production of CIGS solar cells. In-Ga-Se layer were deposited on Mo-coated soda-lime glass, and then the layer was exposed to Cu and Se fluxes to form Cu

We have proposed a composition-monitoring method using heat radiation for an in-line evaporation process. This method utilizes the di!erence of heat radiation from Cu- and (In,Ga)-rich "lms. With this method, we can successfully control chemical comp
