摘要

SCHOTT Solar Thin Film has successfully brought her a-Si/a-Si tandem cell technology for ASI modules to full production. The production site in Jena with a capacity of 35 MW/a started end of 2007 and ramp up was completed in 2008. Due to continuous process improvements the initial power of the best module could be improved to 127 W which corresponds to 9.4% initial aperture efficiency. Indoor and outdoor light induced degradation of the 1.4 m~2 modules is demonstrated to be reproducible around 18%. Recently a new power class with stabilized 103 W could be introduced. Best small area development cells stabilize at 8.5% which give the near term perspective of 110 W stable module power or 8% module aperture area efficiency. A round robin comparison together with various institutes shows a high degree of reproducibility and accuracy for the power measurement of stabilized ASI modules within +/-1%. Long term monitoring of some of our early PV installations demonstrates an excellent stability over more than one decade. Schott ASI modules with thermally isolated rear side reveal a significant annealing effect and show an improved PR of up to 4%.
