Photovoltaic module e.g. solar module, for converting radiation energy contained in sunlight into electrical power, has partially applied detention network layer arranged between transparent conductive oxide and mirror layers

摘要

The module (200) has photovoltaic cells (100) coupled electrically in series, where each cell comprises a photoactive layer stack (3b) that exhibits a n-doped layer (33b), a p-doped layer (31b) and an intrinsic layer (32b). A rear contact (4) arranged on the stack comprises a transparent conductive oxide (TCO) layer (4a), a mirror layer (4c) i.e. metallic layer, and a partially applied detention network layer (4b) that is arranged between the TCO and mirror layers. A partially applied nickel vanadium layer (4d) is located on the mirror layer in a region of an outer photovoltaic cell (100a). The TCO layer is formed as zinc oxide layer or tin oxide layer. The metallic layer comprises silver or a silver alloy. An independent claim is also included for a method for manufacturing a photovoltaic module.
