M416877 V. New description: [New technical field] The solar cell module is a kind of solar cell module, especially the “Tan” solar cell module. [Prior Art] Looking around the life circle of the public The global energy is being rushed to be consumed by the J core in 41 years, 67 years and 9? =; in the case of non-k, the development of solar, wind, geothermal, bio-energy technologies is bound to The more attention is paid to it. In the regenerative energy technology of the public, because solar energy has the characteristics of pollution-free process and no need to maintain the cost, it is generally popular in the world, thus driving the solar cell market to develop in recent years. Under this premise, the issue of solar energy development is second and foremost, thus driving many countries to start implementing new energy policies and implementing subsidy incentives to actively promote the promotion of solar cells. /, According to expert statistics, The energy radiated by the sun to the Earth every year is about 5.4 χ丨俨 joules, and the energy required every year in the world = Ux] 02 G joules; As long as human beings can make full use of one-fifth of the energy that is emitted from the sun to the earth, many of the energy problems facing humanity can be solved immediately. In view of this, it is necessary for 3 M416877 to actively develop solar cells. To solve the energy problem. In order to improve the solar energy utilization of solar cells, when designing solar cells, it is usually sought to increase the travel path length or travel time of the light beam in the photoelectric conversion layer of the solar cell. In a common conventional technique In order to increase the length of the travel path or the travel time of the light beam in the photoelectric conversion layer of the solar cell, a reflective layer is usually added inside the solar cell to reflect the light beam incident from the light incident surface back to the photoelectric conversion layer. For the technical means of adding a reflective layer inside the solar cell, in order to achieve a better reflection effect, when the reflective layer is formed, the surface of the reflective layer usually has a complicated and uneven texture structure. Will make the process of solar cells more complicated, and its products In addition, it is more difficult to control. In addition, a reflective layer is added inside the solar cell, and only a small reflection area in the reflective layer can be used to reflect the light beam, and the effect of improving the utilization of light energy is also rather limited.
