Solar cell with increased efficiency

摘要

A solar cell has a semiconductor body with a radiation-receiving surface having a ribbed structure and having a small pn-junction in the semiconductor body which is matched to follow the contour of the surface of the ribbed structure, and the interstices between adjacent ribs are filled with a material which is highly permeable to the solar radiation and which contains particles for scattering the solar radiation to a high degree situated therein.
