Solar panel structure that increases the effect of pattern color development

The invention relates to a solar panel structure for increasing the effect of pattern color development, in particular to coating a surface of a solar panel with a light-transmissive layer having a pattern or a character to increase the reflective effect, thereby making the pattern or the text of the light-transmitting layer A method and structure for better color development.

Recently, in order to develop environmentally-friendly energy, the use of solar panels has become one of the most mature and widely used technologies in the development of green energy. Currently, solar panels must be placed in outdoor sunshine. It can achieve the preset power generation efficiency. However, in the land use area of the general metropolitan area, if the user wants to install the solar panel, most of them choose the limited space used by fewer people such as the house or the roof of the building to install solar energy. Panel power generation, however, solar panel power generation must have more space to provide a large amount of power, so how to get enough solar panel space and motivate users to resettle is the technical bottleneck that they want to solve today.

Exploring the reason that today's users are only willing to set up solar panels on the roof, such as the lack of access to the roof, the appearance of the solar panels with dark appearance is mostly unsightly for the appearance of the building, and there is no other appearance selectivity, so the building is greatly reduced. Appearance can set the space of the solar panel, including such as the appearance of the building wall or the location of the glass, but instead choose a more beautiful but not energy-efficient advertising or decorative sheet setting, if the wall of the building can be Or installing a glass part of the space to install solar panels will greatly benefit solar power generation.

Based on the above-mentioned prior art background, the present inventors have developed a "solar panel structure having a pattern" and applied for a patent application No. 103113278. Please refer to the solar panel with the pattern shown in FIG. Structure 20, the main feature of the invention patent application is that the surface of the power generation layer 21 disposed on the substrate 24 is coated with a patterned light-transmissive layer 22, and the pattern of the light-transmitting layer 22 maintains a certain light transmittance, wherein the light L After the pattern light transmissive layer 22 is penetrated, sufficient incident light Li or reflected light Lo reflected by the substrate is supplied to generate electric energy in the power generation layer 21 .

The main function of the solar panel structure 20 having the pattern is to display various patterns or patterns through the pattern transparent layer 22, so that the monotonous solar panel can be designed according to the designer's demand under the controllable power generation setting. Arbitrary design of the pattern to be expressed, and the pattern is not patched together for the conventional dot matrix spacer color, so the near view or the far view has better visual effects, and this appearance shows a technical breakthrough. It will encourage more users to beautify the solar panels and install them on more building exteriors or even indoor and outdoor furnishings, which not only provides greater environmental protection and energy efficiency, but also maintains the appearance of the building.

However, the patterned light-transmissive layer 22 of the patterned solar panel structure 20 is attached to the solar panel, and the color of the solar panel is black, and the black color absorbs light, which also represents the Although the pattern light-transmissive layer 22 of the solar panel structure 20 having the pattern has the effect of displaying the pattern, the color of the pattern is also often caused by the color of the solar panel being black, and the pattern color is greatly reduced. Therefore, how to increase the appearance of color is a subject that technology must break through again.

In the case of diversified market demand, there is inevitably a partial demand for solar panels to have better power generation in a certain pattern color rendering effect, or better pattern color development on a certain power generation power. Effect, how to use the solar panel structure 20 with the pattern The design of the pattern transparent layer 22 produces a better surface color development effect, and can control the power generation of the solar panel product, which is another technical problem to be solved.

The invention relates to a solar panel structure for increasing the effect of pattern color development, comprising a solar substrate, a power generation layer and a pattern light transmission layer, wherein the pattern light transmission layer is provided with a pattern layer and a reflective layer.

Another main feature of the present invention is that there is a solar substrate, a power generating layer and a patterned light transmitting layer, wherein the power generating layer and the patterned light transmitting layer have a protective layer, and the patterned light transmitting layer is provided with a patterned layer and a reflective layer, the reflective layer is mixed with a certain proportion of reflective particles, the reflective layer covers the surface of the protective layer, and the reflective layer is covered with a pattern layer, and the thickness of the reflective layer is controlled to control the rough processing on the surface of the protective layer. The undulation height controls the penetration of light into the power generation layer to produce the required power generation, and the refracted light reflection brightness produced by controlling the density of the light-reflecting particles between the light-reflecting layers causes the pattern layer to produce a better color appearance.

A secondary feature of the present invention is that the light reflecting layer is a transparent polymer compound such as an epoxy resin; the pattern layer is a film or a soft light transmissive material; the rough processing on the surface of the protective layer can be protected by sandblasting, grinding or chemical etching. The surface of the layer is roughened.
