CIGSe solar cells with an ink-printing absorber layer were prepared on Mo-coated alumina substrates. The use of alumina substrates can extend the process window to higher temperatures. The inks contained single-phase CIGSe powder, which was formed by firing different selenide powders of Cu2Se, In2Se3, and Ga2Se3 at 800°C. All these powders were synthesized with an environment-friendly and cost-effective powder process. The printed inks were sintered at 600–800°C. The solar cells had power conversion efficiency of 0.50%, an open-circuit voltage of 27 mV, a short-circuit current density of 37 mA/cm2, and a fill factor of 0.50.
