Abstract :
Solarex has applied the buried contact solar cell technology for one-Sun and 18-Sun linear focus concentrator applications. This paper presents results for large area cells fabricated on FZ, CZ and polycrystalline silicon. Chemically textured FZ yields the highest efficiency, with one-Sun cells exceeding 18%. Chemically and mechanically textured CZ cells have exceeded 16% at one-Sun and nearly 19% under 18 Suns concentration. Large area mechanically textured polycrystalline solar cells have been fabricated with efficiencies up to 14.7%. All of these results have been achieved using a dicing saw to cut the grooves
