Abstract

The invention relates to a production method of an invisible-crack-resistant solar component. The production method of the invisible-crack-resistant solar component is characterized by producing a solar cell component by processes of welding solar cell pieces in series, forming a plate, laminating and forming a framework, wherein the process of forming the plate is characterized by disposing a second film layer between a solar battery piece layer and a third film layer; the second film layer is a barrier layer; a film layer structure non-sticking to the third film layer is used for locally separating the third film layer and the solar cell piece layer. The resistance to the invisible crack of the component is greatly improved; the heat dissipation of the component is not influenced; a larger thinning space is provided for other materials, such as glass, EVA, back plates and solace cells, of the component. In addition, the solar component is simple in production process, high in yield, low in attenuation in the using process and long in service life.

Description

technical field [0001] The invention relates to the field of manufacturing solar components, in particular to a production method of an anti-crack solar component. Background technique [0002] With the continuous development of the crystalline silicon solar energy market, more and more quality problems have been exposed, and the industry's understanding of the quality of photovoltaic cell modules has become more and more in-depth. At present, more attention is being paid to micro-cracks in photovoltaic modules, that is, cracks appear in solar cells packaged in photovoltaic modules. Due to the existence of the package and the viscosity of EVA, the fragments of the split battery parts still maintain the original combination and conduction. There is not much change in the appearance and output power in a short time, which can only be measured with an electroluminescence tester (EL). However, in the long run, there is a hidden danger that the thermal expansion and contraction...
