技术领域Technical Field
本发明涉及光伏技术领域，具体涉及一种全黑色太阳能光伏组件生产工艺。The invention relates to the technical field of photovoltaics, and in particular to a production process for a full-black solar photovoltaic component.
背景技术Background technique
光伏组件是分布式光伏系统的关键部件，承担着将光能转化为电能的重任，光伏组件由单片电池片经过串联封装而成，经过串联组件可以获得高电压，多串电池片进行并联而获得高电流。Photovoltaic modules are key components of distributed photovoltaic systems and are responsible for converting light energy into electrical energy. Photovoltaic modules are made up of single-cell batteries packaged in series. High voltage can be obtained by connecting modules in series, and high current can be obtained by connecting multiple strings of batteries in parallel.
市场上，在光伏组件中的电池片镀膜的生产工艺中，都采用氮化硅镀膜，氮化硅镀膜的过程中通入的气体为硅烷和氨气，而且氮化硅的厚度在73-100nm之间，使得光伏组件最终呈现蓝色，就导致了光伏系统在运用的过程中存在着眩光污染，并且对于一些特殊建筑的设计，比如黑色的建筑风格设计的时候，蓝色的光伏组件无法适用，而市场上，部分黑色的光伏组件仅仅是深蓝色，无法做到全黑的效果，因此在全黑色的光伏组件领域需要进一步研究改进。In the market, silicon nitride coating is used in the production process of cell coating in photovoltaic modules. The gases introduced during the silicon nitride coating process are silane and ammonia, and the thickness of silicon nitride is between 73-100nm, which makes the photovoltaic modules appear blue in the end. This leads to glare pollution during the use of photovoltaic systems, and for some special architectural designs, such as black architectural style designs, blue photovoltaic modules cannot be used. On the market, some black photovoltaic modules are only dark blue and cannot achieve a completely black effect. Therefore, further research and improvement is needed in the field of all-black photovoltaic modules.
