SOLAR CELL AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a solar cell, comprising a silicon substrate (1), a front side (2) designed for coupling light, and a rear side (3). It is essential that the front side, at least in a partial region, comprises a front side texture, which along a spatial direction A is periodic, the period length being greater than 1 µm, and that the rear side, at least in a partial region, comprises a rear side texture, which along a spatial direction B is periodic, the period length being smaller than 1 µm. The spatial direction A is disposed at an 80° to 100º angle to the spatial direction B.
