Embodiment Construction

[0102]The invention relates to a method for producing solar cell modules based on semiconductor substrates, for example solar cells made of silicon substrates. Solar cells are usually back-contact solar cells, such as MWT (Metal Through Via), EWT (Emitter Wrap Through), HIT (Heterojunction with Thin Intrinsic Layer), IBC (Interdigitated Back Contact). It is contemplated, however, that in some embodiments the invention also encompasses other solar cell types having front and rear contacts.

[0103] figure 1 A cross section of the solar cell module 10 according to the manufacturing steps according to the embodiment of the present invention is shown.

[0104] As described above, the solar cell module 10 includes a semiconductor substrate-based solar cell 12 . The solar cell 12 has a front surface F and a rear surface R. In this embodiment, the contact region 14 of the solar cell is arranged at the rear surface R. As shown in FIG.

[0105] During this manufacturing step, the s...

Abstract

A method for manufacturing a solar cell module that includes a solar cell (12) based on a semiconductor substrate with front and rear surfaces, includes - fabricating a solar cell from the substrate, and - depositing on at least the rear surface a coating layer. The deposition step includes applying a coating powder (20) on at least the rear surface, forming an adhered powder layer on said surface. The method includes after the deposition step: performing a first annealing process on the solar cell module for transforming the adhered powder layer in a pre-annealed coating layer. Further the method includes -- creating open contacting areas on the solar cell by removal of the adhered powder layer at locations of contacting areas (14) on the solar cell, wherein the removal precedes the first annealing process, or by masking contacting areas on the solar cell, wherein the masking precedes the deposition step.

Description

technical field [0001] The invention relates to a solar cell module and a method for producing the module. Furthermore, the present invention also relates to a solar panel comprising the solar cell module. Furthermore, the invention relates to processing lines and tools for manufacturing such solar cell modules and / or solar panel modules. Background technique [0002] A semiconductor-based solar cell includes a semiconductor substrate having a layer structure of a p-type doped layer and an n-type doped layer forming a p / n junction. [0003] In order to reduce the amount of material in solar cells, thinner substrates tend to be used. Consequently, the substrate becomes more fragile and more difficult to handle during assembly into a solar panel. [0004] In a solar panel consisting of solar cells with all contacts on the rear side, the contacts are usually connected to conductor patterns on the backplane layer. An encapsulant layer having openings corresponding to the pos...
