Embodiment 1

[0032] Such as figure 1 As shown, the method for manufacturing a backplane for photovoltaic module encapsulation in this embodiment includes the following steps: first, compound the thin metal layer 5 and the backplane substrate 14 to form a backplane 1, and the backplane substrate 14 is an insulating material for supporting The thin metal layer 5 is metal aluminum foil. The metal sheet can also consist of two or more layers of different metals, such as aluminum and zinc. The metal thin layer can also be coated with another or several metals on the surface of one layer of metal, such as a layer of zinc and copper coated on the surface of aluminum. The thin metal layer can also be an aluminum alloy.

[0033] Next, forming a connecting circuit on the thin metal layer 5 by etching, specifically includes the following steps: placing the back plate 1 flat on the platform 3 in the corrosion tank 2 with the electrolytic etching solution 6, with the thin metal layer 5 facing upward,...

Abstract

The invention provides a method for manufacturing a backboard used for packaging a photovoltaic module. The method for manufacturing the backboard used for packaging the photovoltaic module solves the problem that mask materials and materials consumed in removing masks in manufacturing a photovoltaic module backboard are wasted and a chemical corrosion technology poorly adapts to the technologies of different metal films. According to the method for manufacturing the backboard used for packaging the photovoltaic module, an electrolytic corrosion method with a template is used for replacing a chemical corrosion method in the prior art, a conducting circuit is formed on a metal thin layer of the backboard in an electrolytic corrosion mode and processes of manufacturing the masks and removing the masks afterwards are removed and thus, materials are saved, cost in manufacturing the backboards is reduced and pressure of environmental pollution is relieved.

Description

technical field [0001] The invention relates to a photovoltaic module manufacturing technology, in particular to a manufacturing technology of a backplane for packaging a single photovoltaic cell into a photovoltaic module. Background technique [0002] With the development of crystalline silicon photovoltaic cell technology, the silicon wafers used to make batteries are becoming thinner and thinner. Thin silicon wafers can reduce the cost of batteries and improve the photoelectric conversion efficiency of batteries, but at the same time, they also bring new challenges to the interconnection, welding and packaging of batteries. There have been many difficulties. For this reason, a packaging method for photovoltaic modules has been developed. In this packaging method, firstly, the positive and negative electrodes of the battery are designed on the back of the battery, and at the same time, the metal thin layer is compounded on the traditional back plate material, and the cor...
