    1. High Efficiency CIGS Thin Film Solar Cells: Laboratory Perspective

    3. Outline High Efficiency CIGS Solar Cells Thin CIGS cells Low Temperature Deposition Deposition from Low Purity Sources Conclusions

    4. Standard Cell Structure

    5. High Efficiency Solar Cells

    23. Demonstrated high efficiency CIGS solar cells with high Voc and fill factors. Efficiency = 19% for Eg of 1.15–1.2 eV. Presented new results on thin CIGS solar cells made by three-stage process and co-deposition. 17% efficiency at 1 µm, 9% at 0.4 µm. Processing at lower temperatures, low purity metals appear promising.
