| dc.description.abstract | In this work, RGS (Ribbon Growth on Substrate) a ribbon silicon material from Bayer AG is characterised, and solar cells from this material, which is presently under development, are processed. Due to the very fast casting process and the lack of kerf losses RGS could be a cost effective alternative to standard cast crystalline silicon wafers in the near future. RGS wafers are characterised with regard to diffusion lengths, crystal defects, transport properties and lifetimes in order to get a deeper inside in the material properties. A solar cell process is developed and optimised based on these results, which takes into account the special needs and properties of RGS silicon. Intensive gettering and H-passivation studies as well as a mechanical texture of the wafer surface led to cell efficiencies of 12 (2x2cm2), which is an overall record on this material. | eng |

| kops.description.abstract | Im Rahmen dieser Arbeit wird mit RGS (Ribbon Growth on Substrate) ein Silizium- Folienmaterial der Firma Bayer AG charakterisiert und Solarzellen aus diesem Material, das sich noch in der Entwicklungsphase befindet, hergestellt. Der schnelle Herstellungsprozess und nicht auftretende Sägeverluste können RGS in Zukunft zu einer kostengünstigen Alternative im Vergleich zu aus Blöcken gesägten kristallinen Silizium-Wafern machen. Um ein besseres Materialverständnis zu erlangen, werden RGS- Ausgangswafer hinsichtlich ihrer physikalischen und elektrischen Eigenschaften untersucht (Diffusionslängen, Kristalldefekte, Transporteigenschaften, Lebensdauern). Aufbauend auf diesen Kenntnissen wird ein Solarzellenprozess entwickelt und optimiert, der auf die besonderen Eigenschaften des Materials abgestimmt ist. Durch intensive Getteruntersuchungen sowie Studien zur Wasserstoffpassivierung von Defekten und eine mechanische Textur der Waferoberfläche ließ sich der Wirkungsgrad auf 12 (2x2cm2) steigern, was einen absoluten Rekordwert für dieses Material darstellt. | deu |
