    摘要： A tandem solar cell structure is described, having the following features: (a) a monolithic structure having at least two different absorbers (104, 108) made from different materials for photovoltaic energy conversion, (b) an absorber (108) consisting of crystalline silicon, (c) a charge-carrier-selective contact on that side of the silicon absorber (108) which is directed to the adjoining absorber (104), (d) a structure of the charge-carrier-selective contact made from a thin interface oxide 107 and an amorphous, semi-crystalline or polycrystalline layer which consists mainly of silicon, is either p-doped (106) or n-doped (201), and is applied to said contact. The charge-carrier-selective contact constructed from the layers 107 and 106 or 201 ensures excellent surface passivation of the crystalline silicon absorber 108 and the selective extraction of a charge carrier type from the latter over the entire surface. A vertical current flow is therefore achieved, with the result that lateral transverse conductivity is not required in each sub-cell. High doping of the layer 106 or 201 may form a tunnel contact with respect to the adjoining layer. The thickness and/or doping of the layer 106 or 201 can be used to adjust the generation currents in the individual sub-cells. The temperature stability of the layers 107, 106 or 201 makes it possible to use subsequent production steps at temperatures of > 400°C.

    摘要： A method for production of a solar cell (1), comprising a semiconductor substrate (2), is disclosed, the electrical contact of which is achieved on the back face of the semiconductor substrate. The back face of the semiconductor substrate comprises locally doped regions (3). The adjacent regions (4) have a different doping from said region (3). According to the invention, short-circuiting of the conducting material (5) of the solar cell may be avoided, whereby both regions (3,4), at least at the boundaries (6) thereof, are coated with a thin electrically-insulating layer (7). Both regions (3,4) are then coated over the whole surface thereof with an electrically-conducting material (5). The separation of the electrically-conducting layers (5) is achieved by application of an etching barrier layer (8) to the whole surface, which is then selectively removed without a mask, for example by laser ablation, locally above the insulating layer (7). By the subsequent attack of an etching solution the etching barrier layer (8) is locally removed from the conducting layer (5) in the region of the openings (9).
