Description

彩色油墨、彩色光伏玻璃、彩色光伏组件及其制备方法
本申请要求在2022年5月16日提交中国专利局、申请号为202210528179.2、名称为“彩色油墨、彩色光伏玻璃、彩色光伏组件及其制备方法”的专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及太阳能光伏技术领域，具体涉及一种彩色油墨、彩色光伏玻璃、彩色光伏组件及其制备方法。
背景技术
太阳能是一种可再生、不受地域限制的清洁能源，近年来随着光伏技术的发展，光伏发电成本快速下降，光伏发电技术被越来越大范围的使用，光伏与建筑相结合也成为光伏应用的领域之一。彩色光伏建筑一体化(Building Integrated Photovoltaic，BIPV)有助于实现光伏构件与多彩建筑环境的融合，符合建筑行业未来装配式、绿色低碳的发展趋势，具有推广前景。光伏组件上添加色彩有多种实现形式，如电池减反膜上色、彩色光电层、彩色封装胶膜、彩色前板玻璃。基于经济及效率考虑，目前商品化的彩色晶硅光伏产品多通过印刷涂层、玻璃镀膜等手段得到彩色前板玻璃实现需求色彩。
传统的彩色涂层玻璃，其涂层通过普通的吸收显色无机颜料与低熔点玻璃粉复合制备，使得玻璃具有较高的硬度及耐候性能，但所选颜料吸收显色原理会使部分光能转化为热能，导致光能利用率偏低。
专利文献1、专利文献2选取干涉显色原理的珠光颜料，降低了颜料对光能的吸收，提升光能利用率，但其油墨涂层的主体由高分子树脂组成，虽然通过加入交联结构提升涂层力学性能，但相对于无机材料，硬度，耐磨，耐候性能仍有欠缺。此外干涉显色的珠光颜料对紫外线具有一定的透过率，降低封装胶膜电池性能，还会带来随角变色效果不适用于建筑幕墙。专利文献3结合紫外固化与高温烧结工艺，UV固化后经过机械压纹提升透光性能、高温烧结能够保证最终无机涂层的耐候性能，但其需要经过紫外固化及高温烧结，工艺复杂，对设备要求高，有机物含量占比30％以上高温烧结时易形成缺陷，涂层上的压孔可能会影响玻璃的耐冲击性能。
此外为了提升太阳能利用效率，已有专利报道采用波长转换材料，将 400nm以下的光转化为可见光范围的光，其中专利文献4、专利文献5将光波转换材料加入封装胶膜中提升光伏组件对光能的利用率。专利文献6采用有机发色团为光波转换材料，利用有机树脂固定在玻璃板上。以上专利均未涉及彩色玻璃及转化后的波长颜色。
因此，有必要开发一种具有较高耐候性能、应用于太阳能电池、能够通过波长转换提升光能利用效率的彩色油墨及彩色光伏玻璃。
