Description

Solar cell module having anti-sagging support structure The present invention relates to the field of photovoltaic power generation technology, and more specifically, to a solar cell module having a sagging prevention structure that includes a support structure supporting a plurality of solar cell cells, thereby preventing the phenomenon of sagging of the solar cell string and simultaneously securing structural rigidity and transparency. Solar cells are energy conversion devices that utilize the photoelectric effect to convert sunlight into electrical energy, and they have a structure that outputs a constant amount of power by connecting multiple solar cells in series or parallel. These solar cells are generally arranged on a substrate made of transparent or translucent material and protected by an encapsulation material, and are configured in the form of strings connecting multiple cells. Recently, there has been a rapid increase in demand for Building Integrated Photovoltaic Systems (BIPV), which are installed on the exterior walls, windows, canopies, and awnings of buildings to simultaneously satisfy both the aesthetic elements of the building and the function of energy production. However, it is difficult to ensure mechanical rigidity in such transparent or translucent solar cell modules, so problems such as string bending or sagging due to gravity in the installation environment frequently occur. When strings sag, the spacing between cells becomes deformed, causing electrodes to break, electrical short circuits, and heat concentration, which leads to problems such as reduced output, localized heating (hot spots), and degradation of the encapsulation layer. Furthermore, microscopic deformations caused by sagging concentrate stress on the cell surface, leading to cracks or interfacial delamination; in the case of transparent modules, this results in non-uniform light transmission and visual distortion, simultaneously degrading both aesthetics and efficiency. Conventionally, methods such as increasing the thickness of the encapsulant or enhancing the rigidity of the external frame have been used to prevent this, but these methods have the side effects of increasing the module's weight and reducing transparency. Furthermore, a completely enclosed internal structure entails problems such as the inability to replace faulty cells and the difficulty of recycling modules that have reached the end of their lifespan. In particular, in large-area applications such as blind-type solar cells or window-type transparent modules, sagging gradually accumulates during long-term use, leading to uneven spacing with the installation surface. This exacerbates issues such as reduced solar angle control and solar tracking efficiency. Therefore, it is necessary to introduce a new support structure that can stably support string-shaped solar cell units while maintaining the transparency and lightweight nature of the entire module. This support structure needs to go beyond the role of a simple reinforcing material and be implemented as a structure that can ensure the mechanical stability and electrical reliability of the module for a long period by simultaneously performing functions such as maintaining the shape of the string, distributing the load, adjusting the angle, and controlling moisture.
