Abstract :
We report the results of production start-up efforts at the 2 MW Sovlux photovoltaic production line. Triple-junction solar cells with higher than 10% initial efficiency were produced in this production line with subcell yield up to 96%. The production process demonstrated high reproducibility and consistency from run to run. 2 ft2 and 4 ft2 modules assembled in the Sovlux plant using these solar cell material have demonstrated an initial efficiency of 9.4%. The solar cell material produced in Sovlux was also shipped to ECD to assemble large area 1.3 ft. by 20 ft. rooftop modules. Lightweight, flexible rooftop modules with initial efficiency up to 9.3% were produced at a high yield
