摘要： The invention relates to a solar cell device comprising a plurality of solar cell modules (Zl, Z2, Z3,..., Zn) whose voltage outputs (UE1, UE2, UE3,..., UEn) are respectively coupled to a voltage transformer (12) by means of a switch element (Tl, 12, T3,..., Tn), wherein said voltage transformer is preferably constructed as an inverting converter or a step-up converter. Losses caused by the partial disconnections of the individual solar cell modules are avoided by the independent operation of said modules. The voltage transformer (12) allows the output voltage to be adapted within a wide range. A microprocessor control unit (16) permits an optimum energy output of the integral system.

摘要： The invention relates to a method and an apparatus for producing series-connected solar cells, wherein the method comprises the following steps: a substrate is introduced into at least one deposition chamber, at least one material layer is deposited on the substrate or a material layer which has already been applied in the deposition chamber, wherein the substrate is applied to a bearing surface, which is curved in the direction of a depositing device, in the deposition chamber, wherein the substrate is flexible and is mechanically prestressed or is curved in a manner corresponding to the bearing surface and the applied layer is patterned using at least one tensioned wire which rests against the substrate, which has been applied to the curved bearing surface, with a defined force and shades the applied material layer or the substrate from the depositing device and thus patterns the material layer to be applied.
