METHOD FOR THE PRODUCTION OF A SOLAR CELL AND SOLAR CELL PRODUCED USING SAID METHOD

摘要

In a method for the production of a solar cell (11), a flat aluminum layer is applied to the rear (22) of a solar cell substrate (13). The aluminum is alloyed into the silicon substrate by the effect of the temperature and forms an aluminum BSF (24). The remaining aluminum that has not been alloyed into the silicon is subsequently removed. The aluminum BSF (24) is transparent to light.
