Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a solar cell, and more particularly to a full-color image solar cell having a transparent coating. [0002] [Prior Art] In order to solve the problem of increasing shortage of energy in recent years and reduce the pollution caused by energy manufacturing to the earth, green energy is actively developed and used, and solar cells are more limited in their installation locations and can It is easy to obtain a source of quantity and is thus actively developing. Among them, thin-film solar cells are rapidly growing in the market because of their low cost and large-scale manufacturing characteristics. The substrate of thin-film solar cells can be formed by using inexpensive materials such as glass, plastic, ceramics, graphite, metal sheets and the like. The film thickness at which the voltage can be generated is only a few micrometers. In addition, since the film can be used as a soft substrate, the application flexibility is also large. Therefore, conventionally used thin film solar cells use glass as a substrate, and are commonly used in canopies, hoods, roofs, and building windows, thereby generating power generation effects, thereby saving a large amount of electricity and effectively achieving energy saving. The effect of saving carbon. [0003] A method of fabricating a thin film solar cell is disclosed in the "METHOD OF MANUFACTURING THIN FILM PHOTOVOLTAIC MODULES" by the US Patent Publication No. US7259321, but the opaque metal layer is used in the mold set, and the transparency is not good. Since the opaque solar cell module will block the user's field of view, it cannot be applied to windows requiring high transmittance, and in order to increase the added value and indoor lighting of thin film solar cells applied to windows, the system utilizes laser 100118814. Form No. A0101 Page 3 of 21 1002031757-0 201248890 The solar cell is etched to form a patterned display area, which in turn makes the overall window more aesthetic and artistic. In addition, the display area has higher light transmittance than other areas, and the indoor lighting is improved. However, in general, lasers are used to etch a thin film solar cell by means of a computer controlled beam switch (on/of f). The display area is formed, but since the position of the desired surname cannot be accurately controlled, there is a problem that the resolution of the display pattern is not good. In addition, the laser of the switch mode can only display the black and white pattern, and cannot achieve the function of gray scale or color pattern display, and therefore, the user's willingness to use can not be improved. In summary, improving the resolution of the pattern display and how to perform color display is one of the improvement goals of the thin film solar cell. SUMMARY OF THE INVENTION The main object of the present invention is to solve the problem of low resolution of pattern display of a thin film solar cell of the prior art.

To achieve the above object, the present invention provides a method for fabricating a full-color image solar cell having a transparent coating, comprising the steps of: forming a transparent photoelectric conversion film on a surface of a first substrate; 52: preparing a second substrate And an encapsulation film disposed between the first substrate and the second substrate; 53: coloring between the first substrate and the second substrate by using a color pigment to form a full color pattern layer; Form No. A0101, page 4 / 21 pages, 1002031757-0 201248890 [0011] S4: bonding the first substrate and the second substrate through the encapsulation film, the first substrate having the surface of the transparent photoelectric conversion film The encapsulation film is bonded and fixed to the second substrate to form a solar cell. [0012] In addition, the present invention also provides a full-color image solar cell having a transparent coating, comprising a first substrate, a transparent photoelectric conversion film formed on the surface of the first substrate, a second substrate, An encapsulation film disposed between the second substrate and the transparent photoelectric conversion film, and a full color pattern layer disposed between the first substrate and the second substrate. The first substrate and the second substrate are combined by the encapsulation film, and the transparent photoelectric conversion film and the full color pattern layer are disposed between the first substrate and the second substrate, and are combined with light irradiation. It can be a grayscale or color pattern display. [0013] As can be seen from the above description, the present invention can have a better light transmittance by the transparent photoelectric conversion film, and thus has an absolute advantage when applied to a window, and can be combined with the setting of the full color pattern layer. Grayscale or colored pattern display. In addition, the present invention does not require the use of a laser for the etching of the pattern, and thus has a relatively simple process step, which can reduce the production cost.
