Description

Solar cell module with support structure The present invention relates to a solar cell module having a support structure. A device that converts the energy of photons generated from the sun into electrical energy through the photoelectric effect is called a solar cell, and an assembly of two or more solar cells connected in series or parallel to a single circuit is called a photovoltaic module. The core material of a solar cell is the light-absorbing layer that exhibits the photoelectric effect, and such materials include silicon, CIGS (Copper Indium Gallium Selenide), CdTe (Cadmium Telluride), Group III-V element composites, photoactive organic materials, perovskites, and quantum dots. Generally, a photovoltaic system is a system that converts light energy into electrical energy using solar cells, and is used as an independent power source for general households or industries, or as an auxiliary power source connected to a commercial AC power grid. The above solar cell is manufactured by forming a p-n junction with semiconductor materials and utilizes the photovoltaic effect, in which a small amount of current flows when receiving light. Most ordinary solar cells consist of large-area p-n junction diodes, and when the electromotive force generated at the positive terminal of the p-n junction diode is connected to an external circuit, it functions as a unit solar cell. Since the electromotive force of a solar cell constructed in this manner is small, multiple solar cells are connected to form a photovoltaic module with an appropriate electromotive force for use. A grid-connected photovoltaic system commonly used as an exterior building system consists of a plurality of solar cell arrays that convert solar energy into electrical energy, and an inverter that converts the direct current (DC) power, which is the electrical energy converted by the solar cell arrays, into alternating current (AC) power and supplies it to the point of use. In such solar power systems, the installation of solar panels to obtain solar energy is the most important element in the system's configuration, and these solar panels are installed either on a separately secured site or on the rooftop of a building. Meanwhile, various solar cells applicable to buildings are being researched to improve their power efficiency, but there are difficulties in developing solar cells applicable to parts requiring transparency, such as windows. In addition, to impart transparency to solar cells, the surface area of the solar cell is adjusted (perforated type), transmittance is improved by thinning the light-absorbing layer (thin-film solar cells), the structure of the solar cell is modified (blind type, vertical type), or optical structures are used (luminescent solar concentrator, LSC). Most of the manufacturing processes for this type of solar cell require complex additional steps. For example, processes such as perforation to form a light-transmitting area, fixing and connecting the solar cell structure, and fabricating and connecting optical structures are required. Furthermore, when using brittle materials such as silicon, it is difficult to implement structures that require flexibility. Meanwhile, conventional solar cell modules have the problem that the solar cells are encapsulated in a material, making it difficult to separate the module when replacing faulty solar cells or recycling waste modules, and also making it impossible to adjust the angle of the solar cells.
