Surface texturing is a common way to enhance the amount of photons absorbed in a material by reducing reflectance and thus can be used to increase the short circuit current of a silicon solar cell. In this work a new promising one-sided wet chemical texture and an optimized SF6/O2 plasma texture are tested on String Ribbon (SR) material. For both textures reflectance measurements are presented and compared to monocrystalline FZ material which is used as reference. Solar cells are produced in a photolithography based high efficiency process. First cell results from plasma textured and non-textured wafers are obtained.
