Preparation and Characterization of Cu(In,Ga)Se₂ Thin Films by Selenization of Cu_0.8Ga_0.2 and In₂Se₃ Precursor Films

Figure 5

Resistivity (squares) and carrier concentration (circles) of CIGS films as a function of selenization temperature. Full and open symbols correspond to CIGS films selenized from Cu-poor precursor films and Cu-rich precursor films, respectively.
