Embodiment Construction
[0071] figure 1 A method for manufacturing a flexible thin film solar cell on a web wound to form a roll is illustrated in , wherein the flexible thin film solar cell is attached to the web having a first side. In detail, its steps are labeled S1...S11 and are explained below.
[0072] Feed of absorber material from roll to handling / processing table is realized at S1. In S2 , the individual cells are released from the absorber material through the cracks in the edges of the individual cells and the contact structures. In S3, the pressing of the battery contact body with light-curing or heat-curing conductive adhesive is realized. Curing of the cell contacts is achieved at S4 by UV light and / or with the aid of an oven. The transfer adhesive tape is supplied to the underside of the absorber material in S5 and is laminated to the underside of the absorber material in S6. Separation of batteries by punching or cutting is realized in S7. Optical testing of each individual cell...

The invention relates to a method for producing thin-film solar modules, comprising the following steps: providing flexible thin-film solar cells as separate segments in a container or on a web wound up to a roll, the flexible thin-film solar cells bearing with a first side against the web, wherein each of the flexible thin-film solar cells is designed to have a first electric pole and a second electric pole; transferring the flexible thin-film solar cells from the web to a first film web such that the first pole of a first flexible thin-film solar cell is positioned next to the second pole of a second flexible thin-film solar cell; and applying electrically conductive contact strips to the first and second poles of the flexible thin-film solar cells in longitudinal and / or transverse direction relative to the conveying direction of the first film web in order to electrically connect the flexible thin-film solar cells in a serial and / or parallel manner; laminating a transparent flexible second thermoplastic film web onto the first film web and the flexible thin-film solar cells in order to form a solar module strand formed by the first and second film webs and the flexible thin-film solar cells located therebetween; separating the plurality of thin-film solar modules from the solar module strand formed; and feeding these separated thin-film solar modules to a crosslinking station.
Description
technical field [0001] This specification describes a method and device for manufacturing a solar cell module with flexible solar cells, and a solar cell module manufactured using the device and according to the method. Background technique [0002] Solar cell modules or photovoltaic modules convert sunlight directly into electricity. It contains the most important component, multiple solar cells. Solar cell modules are characterized by their electrical power ratings (especially open circuit voltage and short circuit current). These are related to the nature of the individual cells and the interconnection of the solar cells within the module. [0003] Typically, a solar cell module has an embedded material and a back structure in addition to electrically interconnected solar cells. The top layer provides protection against mechanical and climatic influences. The embedding material and the top layer must be transparent in order to keep the absorption losses in the spectra...
