Embodiment Construction

[0023] The solar cells and photovoltaic modules are described in conjunction with the drawings, in which the improved front contact structure of the solar cells is responsible for reducing finger interruptions and cell cracks.

[0024] figure 1 The optoelectronic module 200 is shown in a schematic side view. A schematic top view of the front side of the photoelectric module is shown in figure 2 Given in. The photovoltaic module 200, also referred to as a solar module below, has a certain number of silicon solar cells 100 electrically connected to each other. In operation, the photovoltaic module 200 is irradiated to the sun by its front side, and a part of the rays is absorbed by the solar cell 100 and converted into electrical energy. The solar cell 100 generally has a square structure. However, other shapes can also be realized. The solar cell 100 arranged in a plane in the photovoltaic module 200 is located between the glass cover plate 210 on the front side and the thin f...

Abstract

The invention relates to a photovoltaic module with a plurality of solar cells, each comprising a contact structure on a pretreated silicon wafer, said contact structure having a plurality of parallel contacts in a first direction. The arranged linear contact fingers and at least one bus bar arranged perpendicular to the first direction. The busbars run in a second direction across the contact fingers and each have a contact surface in the area of ​​the contact fingers, which protrude beyond the contact fingers in the second direction and are in contact with the contact fingers. The contact refers to an electrical connection. At least one cell connector for connecting the solar cells is provided, the at least one cell connector being distributed across the busbar of at least one solar cell and electrically connected to a contact surface of the busbar, wherein the The width of the battery connector is smaller than the length of the contact surface in the first direction.

Description

Technical field [0001] The present invention relates to a photovoltaic module, which has a plurality of solar cells, the solar cell has a front-side contact structure, the front-side contact structure includes a plurality of parallel arranged linear contact fingers and at least one perpendicular to it Distribution of bus bars. Background technique [0002] Solar cells are used to convert electromagnetic radiation energy, especially sunlight, into electrical energy. The energy conversion is based on the absorption of radiation in the solar cell, thereby generating positive load carriers ("electron-hole-pairs"). Then, the generated free carriers are separated from each other to be directed to the separated contacts. [0003] A solar cell generally has a square silicon substrate, and two regions with different electrical conductivity or doping are formed in the silicon substrate. A p-n junction is formed between two regions, also called "base" and "emitter". The p-n junction gener...
