Work on the development of large area, high efficiency P/N solar cells is described. The best performance achieved to-date on 3'' diameter cells is 15.6% at AM1 and 28/sup 0/C. Factors contributing toward the poor performance have not been identified and isolated. Work is continuing. Minor modifications have been incorporated in the modular design. The 120 cells will be connected 8 in parallel and 15 in series to enhance the reliability of the modules. As a result of the changes, two junction boxes will be required as the P and N terminals will come out from the opposite sides of the module. Designs for back contact soldering machine, vacuum pick-up, AR coating tooling, and test fixture have been completed. Fabrication of tooling has begun.
