Description of the Invention: [Technical Field] The present invention relates to a thin film solar cell, and more particularly to a "thin film solar cell and process capable of displaying an image", which is covered by a mask and a laser scribing line. Thin-film solar cells display existing images to enhance their added value. [Prior Art] Due to global climate change, air pollution problems and the shortage of resources, the possibility of solar power as one of the main sources of power supply has been increasingly attracting attention. This is also the main source of rare wafers in recent years. The reason for the rapid growth of the solar cell market, however, is that the cost of silicon-based solar power technology is much higher than that of traditional power generation. Therefore, the market is still limited to specific uses. So the world's major research The company is committed to investing in solar-related technologies. The company is seeking to develop new substances that can reduce product costs and improve efficiency. Among them, thin-film solar cells can be used in low-cost glass, plastic, ceramics, and graphite. Different materials such as metal sheets are fabricated on the substrate, and the thickness of the film that can generate voltage is only required to be several times/zm. Compared with the thickness of the germanium wafer, the material is used very little, and since the film can be used as a soft substrate. , the application of flexibility, therefore, a thin film solar cell, using glass Glass is a substrate and is commonly used in windows of buildings to generate power generation, which saves a lot of electricity bills and effectively achieves energy saving and carbon saving effects. Looking at the above-mentioned conventional structure, it is not difficult to find that there are still some shortcomings. The main reasons are as follows: 201138129 (1) The thin solar cell system uses sunlight to generate electricity, so it has a considerable degree of isolation of sunlight. There is a lack of indoor lighting, which reduces the willingness to apply thin film solar cells to windows. (1) When a thin film solar cell is applied to a window, it does not have the effect of displaying an image, which means that the touch value cannot be improved. The inventor has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation of the above objectives, the present invention has finally achieved the practical use of the present invention. SUMMARY OF THE INVENTION The technical problem to be solved is that the thin-film solar cell uses sunlight to generate electricity, so that there is a considerable degree of isolation of the sunlight. Therefore, there is a situation in which indoor lighting is insufficient, so that the intention to apply the thin film solar cell to the window is lowered. Moreover, the film too soup battery does not have the effect of displaying an image, and there is a lack of improvement in its added value. Φ Technical Features for Solving the Problem: A thin film solar cell and process for displaying images, the thin film solar cell system comprising a substrate and a reaction layer, the substrate having light transmissivity and being a hard glass material or a Made of a soft plastic material, the reaction layer comprises a film layer (pin layer) and a conductive film layer (AZ〇 & Ag), and the reaction layer is formed at one end surface of the substrate, and the reaction layer is partially passed through a thunder The off-line method is used to remove the film layer and the conductive film layer (AZO & Ag). With the above structure, the laser-lined portion is formed with a hollowed-out region, and the hollowed-out region is matched with the non-penetrating laser portion. Display existing images. 201138129 The process steps are as follows: a, clear silk surface, the film too miscellaneous battery is placed in deionized water to oscillate, thereby cleaning the surface; b, drying, the cleaned thin film solar cell is placed in the oven, thereby removing the surface Moisture; e, reticle, with the 3rd picture does not 'flat the light mask with a blackout pattern on the thin film solar cell; d, the laser age' will put the thin solar energy battery in the laser age machine, its thunder The parameters of the line marking machine are wavelength 532nm, the pitch is 〇·5 coffee, and the power is 400W, and the laser scribe line is performed by the end face of the reticle; e, the surface is cleaned, the reticle is removed, and the ion absorbing is oscillated The removal of the powder residue after the laser scribing, that is, the image of the reticle can be displayed on the surface of the thin film solar cell, and the power generation amount is tested, and the efficiency of the thin film solar cell after the laser scribing is only slightly decreased. Does not affect its power generation effect. In contrast to the effects of the prior art: (1) The reaction layer of the thin film solar cell has a hollowed out area by a laser line, and the light transmittance is increased by the hollow area to provide a lighting application. (2) The hollowed out area of the reaction layer is combined with the portion that is not penetrating the laser to form an image, which can increase the added value by displaying the image of the thin film solar cell. [Embodiment] In order to enable the reviewing committee to have a better understanding and understanding of the purpose, features and effects of the present invention, please refer to the following section for a brief description of the following: First, please refer to Figure 1 and Section 2.
