Abstract:
A tandem solar cell structure is described with the following features: (a) Monolithic configuration with at least two different absorbers ( 104, 108 ) of different materials for photovoltaic energy conversion (b) an absorber ( 108 ) consisting of crystalline silicon (c) a charge carrier selective contact arranged on the side of the silicon absorber ( 108 ) directed to the adjacent absorber ( 104 ) (d) configuration of the charge carrier selective contact from a thin interface oxide  107  and an amorphous, partially crystalline or polycrystalline layer applied thereto, mainly consisting of silicon, either p ( 106 ) or n doped ( 201 )   The charge carrier selective contact made up of layers  107  and  106  or  201 , respectively, ensures excellent surface passivation of the crystalline silicon absorber  108 , as well as selective extraction of a charge carrier type from the latter over the entire surface. Thus, a vertical current flow is achieved, so that lateral transverse conductivity is not required in every sub-cell. The formation of a tunnel contact to the adjacent layer may be achieved by high doping of the layers  106  and  201 . The thickness and/or the doping of the layers  106  and  201  may be used to match the generation currents in the individual sub-cells. The temperature stability of layers  107, 106  or  201 , respectively, allows the application of subsequent manufacturing steps with temperatures >400° C.

Claim (Index 15):
