In particular, the first colored region and the second colored region together constitute an overall colored region of the photovoltaic module.

Implicitly, the first colored region is complementary to or partially coincides with the second colored region. Where complementary means that the first coloured area covers part of the photovoltaic module, the second coloured area covers the remainder of the photovoltaic module, and the first coloured area and the second coloured area in combination completely cover the whole of the photovoltaic module, i.e. the first coloured area is the absolute complement of the second coloured area. Or the first colored region covers part of the photovoltaic module, the second colored region covers part of the photovoltaic module, the first colored region and the second colored region are combined together to completely cover the whole photovoltaic module, and meanwhile, a certain overlapped part exists between the first colored region and the second colored region, namely the first colored region is a relative complement of the second colored region.

Otherwise, partially overlapping means that the first colored area covers part of the photovoltaic component and the second colored area covers the whole of the photovoltaic component, i.e. the first colored area is a subset of the second colored area.

Wherein, the bottom layer of the adhesive coating can be made of transparent adhesive. With this structural design, the color backsheet layer 102 becomes the second color region of the auxiliary color layer. Therefore, the color cell chip layer 100 and the color back plate layer 102 jointly form a comprehensive color area of the photovoltaic module, so that the photovoltaic module is integrally colored, and the overall attractiveness of the photovoltaic module is effectively improved.

Further, the auxiliary color layer further includes a color adhesive film layer 103 disposed between the color back sheet layer 102 and the color battery chip layer 100. Wherein the color of the color film layer 103 is visually consistent with the color of the color battery chip layer 100. The colored thermoplastic high molecular polymer or other chemical colored molecules can be integrated with the adhesive film to ensure the adhesive property and the packaging effect of the adhesive film, or the colored film layer is arranged in the double-layer packaging adhesive film layer to form an integrated colored adhesive film. The color adhesive film layer 103 is arranged on the backlight surface of the color battery chip layer 100, and the absorption utilization rate of the photovoltaic module to illumination cannot be influenced by the color of the adhesive film. Under the structural design, the color back plate layer 102 and the color film layer 103 together form a second color region of the auxiliary color layer. Therefore, the color cell chip layer 100, the color back plate layer 102 and the color film layer 103 jointly form a comprehensive color area of the photovoltaic module, so that the photovoltaic module is integrally colored, and the overall attractiveness of the photovoltaic module is effectively improved.
