本发明涉及光伏发电领域，具体是一种可弯折的电池光伏组件封装结构。The invention relates to the field of photovoltaic power generation, in particular to a bendable battery photovoltaic component packaging structure.
背景技术Background technique
太阳能电池组件是由高效单晶/多晶太阳能电池片、低铁超白绒面钢化玻璃、封装材料、功能背板，互联条，汇流条，接线盒以及铝合金边框组成。使用寿命可达15-25年。单体太阳电池不能直接做电源使用。作电源必须将若干单体电池串、并联连接和严密封装成组件。太阳能电单晶太阳能电池组件也叫太阳能电池板、光伏组件,是太阳能发电***中的核心部分，也是太阳能发电***中最重要的部分。其作用是将太阳能转化为电能，或送往蓄电池中存储起来，或推动负载工作。太阳能电池组件的质量和成本将直接决定整个***的质量和成本。The solar cell module is composed of high-efficiency monocrystalline/polycrystalline solar cells, low-iron super white suede tempered glass, packaging materials, functional backplanes, interconnection bars, bus bars, junction boxes and aluminum alloy frames. The service life can reach 15-25 years. Single solar cells cannot be used directly as power sources. As a power source, several single cells must be connected in series, in parallel and tightly sealed into components.

晶硅组件具有效率高，价格低的优点，但是由于硅片属于刚性材料，材质较硬又容易碎裂，所以一般的光伏组件均需要使用刚性材料对光伏组件进行保护。由于刚性材料的存在，现有的光伏组件均只能做成一个平面的整体，不可弯折，即便是现在有一些公司开发了一些柔性晶硅光伏组件，但是这种组件只能进行一次弯折，不能进行重复弯折，而且弯折的程度有限，且只能进行二维的弯折。Crystalline silicon modules have the advantages of high efficiency and low price. However, since silicon wafers are rigid materials, the material is hard and easily broken, so ordinary photovoltaic modules need to use rigid materials to protect the photovoltaic modules. Due to the existence of rigid materials, the existing photovoltaic modules can only be made into a flat whole and cannot be bent. Even though some companies have developed some flexible crystalline silicon photovoltaic modules, such modules can only be bent once , Repeated bending cannot be performed, and the degree of bending is limited, and only two-dimensional bending can be performed.
目前有一些专利对可弯折晶硅光伏组件进行了一些阐述，如专利CN109768107A，公布一之中折叠式的光伏组件，该专利在电池片中间设有弯折间隙，使组件进行一定的弯折性。另外如专利CN 208874521 U专利中，使用不同的光伏单元，在不同的光伏单元中间设定转动件以达到弯折的目的，目前的专利能够到达一定程度的弯折效果，但是没有彻底解决问题。在CN109768107A专利中，和目前柔性组件并没有本质的区别，并没有解决光伏组件不能反复弯折以及保护电池片的问题，而CN 208874521 U中，光伏组件通过转动件进行弯折，需要在光伏组件完成后加装配件，操作复杂且灵活度不高，而且并没有解决光伏组件不能在三维方向弯折的问题。另外，由于目前大多数光伏电池需要使用焊带进行连接，而在组件弯折过程中，焊带容易出现断裂的问题。At present, there are some patents on bendable crystalline silicon photovoltaic modules, such as patent CN109768107A, which publishes a foldable photovoltaic module. This patent has a bending gap in the middle of the cell, so that the module can be bent to a certain extent. Sex. In addition, in the CN 208874521 U patent, different photovoltaic units are used, and rotating parts are set in the middle of the different photovoltaic units to achieve the purpose of bending. The current patent can achieve a certain degree of bending effect, but it does not completely solve the problem. In the CN109768107A patent, there is no essential difference from the current flexible components, and it does not solve the problem that the photovoltaic module cannot be repeatedly bent and protect the cells. In CN 208874521 U, the photovoltaic module is bent by a rotating part, which requires After the completion of the installation of accessories, the operation is complicated and the flexibility is not high, and it does not solve the problem that the photovoltaic module cannot be bent in the three-dimensional direction. In addition, since most photovoltaic cells currently need to be connected using solder ribbons, the solder ribbons are prone to breakage during the bending process of the components.
