Cu(In,Ga)Se2 Based Submodule Process Robustness

    Research output: Contribution to conferencePaper


    Submodule efforts have resulted in improved module design concepts as is demonstrated by: (1) a world record 13% conversion efficiency for a 40.4 cm/sup 2/ laminated 20 segment submodule, and (2) the ability to produce submodules of high FF (>70%) without other substantial losses relative to reference devices. The quality of our deposition systems for larger areas is tested and calibrated by theuse of 3x3 matrices of 3' x 3' substrates covering an area of over 500 cm/sup 2/. A high quality, high throughput (down to 10 min. deposition times) CIGS absorber processs is established and exhibits a high degree of controllability as well as tolerance to compositional fluctuations. Results of laser interconnect patterning are also shown.
