    <dcterms:abstract xml:lang="eng">In this work we investigated local rear contact structures and compared these to the full area Al-BSF structure. Two processes for local contacts are presented: The laser fired contact (LFC) process and a screen printing process to create a local back surface field (SP-LBSF) structure. The rear side passivation is provided by a firing stable SiO2/SiNx-stack, using a thin dry thermal SiO2 and a PECVD SiNx. We analyzed several process schemes to implement the local rear side structure with a screen printed front side metallization. As a flat rear side is very important for a successful implementation of a solar cell process with dielectric layer passivation, we focused on these processes. Monocrystalline Cz-Si solar cells (cell size 125x125 mm²) with an LFC structure and up to 17.6% efficiency were processed. The fabricated LFC cells show an increased reflectivity at long wavelengths due to the evaporated aluminum on the rear side. Furthermore, the internal quantum efficiency of the LFC and the SP-LBSF solar cells in the long wavelength range is significantly higher than for solar cells with aluminum back surface field.</dcterms:abstract>
