摘要： The invention relates to a solar cell, comprising a silicon layer which has a dopant of a first dopant type, a front designed for the coupling in of light, and a rear, the silicon layer being a doped base layer, at least one textured layer and a metal layer being arranged on the rear of the silicon layer, optionally on additional intermediate layers, and the textured layer comprising a rear texture in at least a section thereof which rear texture is designed as an optical diffraction structure. It is essential that at least one textured intermediate structure (3, 23, 33) is arranged between the textured layer (2, 22, 32) and the metal layer (4, 24, 34), the metal layer (4, 24, 34) being connected to the textured layer (2, 22, 32) and/or to the base layer (1, 21, 31) in an electrically conducting manner. The textured intermediate structure (3, 23, 33) is substantially transparent at least in the wavelength range of 800 nm to 1100 nm and has a refractive index n smaller than the refractive index of the textured layer in at least this wavelength range. The refractive index of all layers arranged between the base layer (1, 21, 31) and the textured intermediate layer (3, 23, 33) deviates by not more than 30% relative to the refractive index of silicon and the layer which is arranged directly on the rear of the base layer (1, 21, 31) is a passivation layer which passivates the surface with respect to the recombination of minority charge carriers.
