Abstract

The invention discloses a thin film solar battery module and a process for preparing the module, wherein the module is divided into a plurality of modular units by a scribing groove, an extraction electrode is respectively arranged on phototropic conductive film of each modular unit, and both ends of the extraction electrode are connected with negative phototropic conductive film of a next modular power supply. The process for preparing the module comprises the following steps: arranging a plurality of the extraction electrodes on phototropic conductive film after plating the negative phototropic conductive film, a generating layer and the phototropic conductive film on a substrate, or orderly arranging the extraction electrodes, the phototropic conductive film and the generating layer and the negative phototropic conductive film on the substrate, then cutting the module to by a scribing machine form a plurality of the modular units, enabling each of the modular unit to have the extraction electrode, and the extraction electrode of each unit is connected with the negative phototropic conductive film of the next unit, lastly packing into a battery module. The method reduces the technique time, greatly simplifies the technique steps, reduces the pollution to the battery, which is caused by the multitime scribing and the washing, simultaneously, the invention has the advantages that the cost of manufacturing devices is low, the depletion of the electric energy production of the module is low, the product weight is light, and the freedom degree of designing the standard parameter of the battery is high and the like.

Description

technical field [0001] The invention relates to a thin-film solar battery module and a processing method thereof. Background technique [0002] Thin-film solar cells have become the most promising new type of solar cells due to the characteristics of low material consumption, low cost and wide application, and have become a key project and hot topic in the research and development of photovoltaic technology in the world today. Its types include silicon-based thin-film solar cells, CdTe cadmium telluride-based thin-film solar cells, and CIS copper-indium-selenium-based thin-film solar cells.

Problems solved by technology

The automation cost of this module integration method is high: because the space loss caused by the integration of each unit is large, in the final packaging, two substrates are required to package the module, resulting in increased costs and increased product weight.

At the same time, it is relatively difficult to design for high voltage and low current
