According to the photovoltaic panel, the white layers are arranged to be a plurality of white Yan Liaoxian which are parallel to each other, the gaps between the pigment wires can enable visible light to directly enter the photovoltaic panel without passing through the white pigment layers, and compared with a conventional complete and continuous white layer arrangement mode in the field, the photovoltaic panel can transmit more visible light, and the blocking of the white layers to the visible light is reduced;
in addition, if the compactness of the white pigment lines is proper, the degree that the gaps among the white pigment lines are difficult to distinguish by naked eyes can be achieved, and the attractive effect is hardly influenced; or it may be made to such an extent that the lines are clearly visible to the naked eye to create a special pattern effect.
In some embodiments of the present application, referring to fig. 2, the color layer 2 is formed by a plurality of color pigment lines parallel to each other and arranged along a second direction, and a predetermined included angle is formed between the first direction and the second direction.

The test results are shown in the following table:
| generating power (W) | |
| Example 1 | 51.0 |
| Example 2 | 53.1 |
| Example 3 | 52.6 |
| Example 4 | 52.2 |
| Example 5 | 52.1 |
| Example 6 | 52.7 |
| Example 7 | 52.6 |
| Example 8 | 52.1 |
| Comparative example | 47.3 |
As can be seen from the above table, the generated power of each of examples 1 to 8 is significantly higher than that of the comparative example, which shows that the preparation of the white layer and the color layer in the form of the pigment lines can increase the visible light incident to the photovoltaic panel, thereby improving the generated power.
In examples 2-4, the angle between the white pigment line and yellow Yan Liaoxian was gradually decreased, and the generated power was decreased accordingly, which indicates that the incident visible light was the greatest at an angle of 90 °.
The generated power of example 2 is significantly higher than that of examples 5-8, which suggests that the pigment lines employed in example 2 are more suitable in width and spacing, which is advantageous for increasing the incidence of visible light.
Various embodiments of the present application may exist in a range format; it should be understood that the description in a range format is merely for convenience and brevity and should not be interpreted as a rigid limitation on the scope of the application. It is therefore to be understood that the range description has specifically disclosed all possible sub-ranges and individual values within that range. For example, it should be considered that a description of a range from 1 to 6 has specifically disclosed sub-ranges, such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., as well as single numbers within the range, such as 1, 2, 3, 4, 5, and 6, wherever applicable. In addition, whenever a numerical range is referred to herein, it is meant to include any reference number (fractional or integer) within the indicated range.
In this application, unless otherwise indicated, terms of orientation such as "upper" and "lower" are used specifically to refer to the orientation of the drawing in the figures. In addition, in the description of the present application, the terms "include", "comprise", "comprising" and the like mean "including but not limited to". Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element. Relational terms such as "first" and "second", and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Herein, "and/or" describing an association relationship of an association object means that there may be three relationships, for example, a and/or B, may mean: a alone, a and B together, and B alone. For the association relation of more than three association objects described by the "and/or", it means that any one of the three association objects may exist alone or any at least two of the three association objects exist simultaneously, for example, for a, and/or B, and/or C, any one of the A, B, C items may exist alone or any two of the A, B, C items exist simultaneously or three of the three items exist simultaneously. Herein, "at least one" means one or more, and "a plurality" means two or more. "at least one", "at least one" or the like refer to any combination of these items, including any combination of single item(s) or plural items(s). For example, "at least one (individual) of a, b, or c," or "at least one (individual) of a, b, and c," may each represent: a, b, c, a-b (i.e., a and b), a-c, b-c, or a-b-c, wherein a, b, c may be single or multiple, respectively.
The foregoing is merely a specific embodiment of the application to enable one skilled in the art to understand or practice the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
