Description

一种效能提升的彩色光伏组件及其制备方法 技术领域
本发明属于光伏组件技术领域，具体涉及一种效能提升的彩色光伏组件及其制备方法。
背景技术
随着建筑光伏一体化概念在光伏领域中得到了越来越广泛的认同，对于作为建筑材料的光伏产品，人们希望能够选择自己喜欢的颜色来装扮自己的建筑，彰显建筑的个性，这就要求光伏组件具有各种颜色以适应美观的要求。现有的彩色光伏组件的形成方式一般有两种，一种是直接在丝网印刷机或UV印刷机上印刷白墨层再在白墨层上印刷彩墨层形成彩色光伏组件；另一种是先在玻璃板上印刷彩墨层，然后再在彩墨层上印刷白墨层，再通过封装的方式将玻璃板与光伏组件封装在一起，形成彩色光伏组件。由于光伏组件中的光伏晶片自身的颜色为黑色或者蓝色，如果不印刷白墨层，彩墨层的颜色会比较暗，不饱满，色彩也不鲜艳，印刷白墨层能够使彩墨层的颜色更加饱满，使彩墨层更加艳丽。但是白墨层以及彩墨层对太阳能光线有较强的遮蔽作用，被遮蔽的光伏晶片，将被当作负载消耗其他有光照的太阳能电池组件所产生的能量，被遮蔽的光伏晶片此时会发热，形成热斑效应，这种热斑效应严重的降低了光伏晶片的能效。而且白墨层中的二氧化钛颗粒也对照射到太阳能光伏组件上的光进行反射，降低太阳能光伏组件的能效。
发明内容
为解决上述技术问题，本发明的第一个方面提供了一种效能提升的彩色光伏组件，从上到下依次包括承载色彩的图案部、太阳能光伏组件，所述图案部至少包括印刷形成的白墨层和印刷形成图案的彩墨层。

D:通过打印软件将文档二编辑为印刷软件可以识别的文档四，并通过印刷软件控制印刷机，使印刷机印刷成为彩墨层。
优选的，所述步骤C中通过印刷机印刷成为白墨层时，印刷机只出白墨，印刷软件通过识别文档三中的色阶控制印刷机中白墨的出墨量，色阶为255的白墨出墨量为100％，色阶降低，出墨量也随之降低，色阶为0的白墨出墨量为0％，每平方米白墨层的出墨量在5-15ml。
优选的，所述步骤D中通过印刷机印刷成为彩墨层时，印刷软件通过识别文档四中的色阶控制印刷机中彩墨的出墨量，色阶为0的不出墨，同时色阶为255的也不出墨，其余色彩为100％出墨量。
有益效果：本技术方案中通过调整带有所需图案的图片的色阶，使打印软件通过识别图片中的不同色阶，控制印刷机印刷白墨层时白墨的出墨量，同时控制打印机印刷彩墨层时黑色地方和白色地方不出墨。通过这种方法不仅减少了白墨的使用量，降低了彩色光伏组件的生产成本，还能有效降低光伏组件的遮蔽效应，减少白墨层对太阳光的反射，增加太阳光线的透过率，有效提高光伏组件的效能和光伏组件的安全性，还能充分利用光伏晶片自身的黑色，有效的增加图案的立体感，使图案的色彩层次更加明显，丰富。

具体实施方式
为了下面的详细描述的目的，应当理解，本发明可采用各种替代的变化和步骤顺序，除非明确规定相反。此外，除了在任何操作实例中，或者以其他方式指出的情况下，表示例如说明书和权利要求中使用的成分的量的所有数字应被理解为在所有情况下被术语“约”修饰。因此，除非相反指出，否则在以下说明书和所附权利要求中阐述的数值参数是根据本发明所要获得的期望性能而变化的近似值。至少并不是试图将等同原则的适用限制在权利要求的范围内，每个数值参数至少应该根据报告的有效数字的个数并通过应用普通舍入技术来解释。
尽管阐述本发明的广泛范围的数值范围和参数是近似值，但是具体实例中列出的数值尽可能精确地报告。然而，任何数值固有地包含由其各自测试测量中发现的标准偏差必然产生的某些误差。
当本文中公开一个数值范围时，上述范围视为连续，且包括该范围的最小值及最大值，以及这种最小值与最大值之间的每一个值。进一步地，当范围是指整数时，包括该范围的最小值与最大值之间的每一个整数。此外，当提供多个范围描述特征或特性时，可以合并该范围。换言之，除非另有指明，否则本文中所公开之所有范围应理解为包括其中所归入的任何及所有的子范围。例如，从“1至10”的指定范围应视为包括最小值1与最大值10之间的任何及所有的子范围。范围1至10的示例性子范围包括但不限于1至6.1、3.5至7.8、5.5至10等。
为解决上述技术问题，本发明的第一个方面提供了一种效能提升的彩色光伏组件，从上到下依次包括承载色彩的图案部、太阳能光伏组件，所述图案部至少包括印刷形成的白墨层和印刷形成图案的彩墨层。
作为一种优选的技术方案，所述图案部从上到下依次包括彩墨层和白墨层，所述太阳能光伏组件从上到下依次包括第一玻璃层、第一胶膜层、光伏晶片层、第二胶膜层和功能背板层。

作为一种优选的技术方案，所述图案部从上到下依次包括第一玻璃层、彩墨层和白墨层，所述太阳能组件从上到下依次包括第二玻璃层、第二胶膜层、光伏晶片层、第三胶膜层和功能背板层，所述图案部通过第一胶膜层与太阳能光伏组件相粘结。
作为一种优选的技术方案，所述彩墨层的厚度在0-0.05mm。
作为一种优选的技术方案，所述彩墨层的厚度在0-0.0118mm。
作为一种优选的技术方案，所述白墨层的厚度在0-0.04mm。
作为一种优选的技术方案，所述白墨层的厚度在0-0.02mm。
发明人发现白墨层中的主要原料为二氧化钛，二氧化钛很容易将透射到白墨层上的一部分太阳光反射掉，减少透射到太阳能电池片上的太阳光，降低光伏组件的效能。
本发明的第二个方面提供了一种效能提升的彩色光伏组件的制备方法，至少包括步骤：将图案部与太阳能光伏组件相结合。
作为一种优选的技术方案，所述图案部中的白墨层和彩墨层的具体印刷方法为：
A:将带有所需图案的图片通过图片处理软件进行处理，将图片调整为灰度模式，并建立白色专色通道，存储为打印软件可识别的文档一；
B:将带有所需图案的图片通过图片处理软件进行处理，在图片上建立曲线调整图层，并将黑度值降到最低，存储为打印软件可识别的文档二；
C:通过打印软件将文档一编辑为印刷软件可以识别的文档三，并通过印刷软件控制印刷机，使印刷机印刷成为白墨层；
D:通过打印软件将文档二编辑为印刷软件可以识别的文档四，并通过印刷软件控制印刷机，使印刷机印刷成为彩墨层。
作为一种优选的技术方案，所述步骤C中通过印刷机印刷成为白墨层时，印刷机只出白墨，印刷软件通过识别文档三中的色阶控制印刷机中白墨的出墨量， 色阶为255的白墨出墨量为100％，色阶降低，出墨量也随之降低，色阶为0的白墨出墨量为0％，每平方米白墨层的出墨量在5-15ml。
作为一种优选的技术方案，所述步骤D中通过印刷机印刷成为彩墨层时，印刷软件通过识别文档四中的色阶控制印刷机中彩墨的出墨量，色阶为0的不出墨，同时色阶为255的也不出墨，其余色彩为100％出墨量。
发明人在实验过程中发现，通过控制白墨的出墨量不仅能够减少白墨层对太阳光的反射，提高太阳光的透过率，提高光伏组件的整体效能，还能降低整体光伏组件的生产成本，但是控制彩色墨的出墨量，光伏组件没有明显的效能提升，而且图案的色彩饱和度和艳丽感会下降很多，发明人主要通过调整白墨的出墨量，提高光伏组件的能效。
另外，如果没有其它说明，所用原料都是市售得到的。
