Solar Cell

A solar cell comprising a semiconductor layer (1) with first doping, an inducing layer (3) arranged on the semiconductor layer (1) and an inversion layer (4) or accumulation layer (4) which due to the inducing layer (3) is induced underneath the inducing layer (3) in the semiconductor layer (1) is characterised in that the inducing layer (3) comprises a material with a surface charge density of at least 1012 cm-2, preferably of at least 5x1012 cm-2, more preferably of at least 1013 cm-2
