Patent Abstract

The invention relates to a solar module, also referred to as a solar cell, with a layer arrangement comprising at least one substrate, a first electrical contact layer, an active semiconductor layer, a second electrical contact layer, an insulator layer and a further third contact layer, with a plurality of photovoltaic elements (A, B, C...) arranged in parallel and series-connected to one another, wherein within the area of a respective photovoltaic element (A, B, C...), whose area is determined by the length L and the respective width B of the photovoltaic element, channels are distributed in periodic arrangement, which electrically conductively contact the first electrical contact layer with the further third contact layer. The invention further relates to a method for manufacturing and series-connecting photovoltaic elements to form a solar module, in which at least a first electrical contact layer, a semiconductor layer, a second electrical contact layer, an insulator layer and a further electrical contact layer are applied to a substrate, a structuring of the solar module surface into individual photovoltaic elements (A, B, C, ...) and a subsequent series-connection of these elements is carried out, wherein according to the invention within the area of a respective photovoltaic element (A, B, C...), whose area is determined by the length L and the respective width B of the photovoltaic element, channels are distributed in periodic arrangement, which electrically conductively contact the first electrical contact layer with the further third contact layer.
