Description
Technical Field
The invention relates to the field of packaging adhesive films for photovoltaic modules, in particular to a light synergist and a synergistic packaging adhesive film for a photovoltaic module.
Background
With the continuous development of science and technology, the global resource consumption is serious, and the energy war has become the focus of attention of all countries around the world. Although energy conservation and consumption reduction projects have been implemented globally, the resource consumption rate is slowed down, but as a strategic reserve, non-renewable resources are still consumed rapidly. Against this background, the development of renewable energy sources has become very slow. The photovoltaic industry based on the photoelectric conversion effect rapidly becomes a key point of new energy development due to the characteristics of no pollution, reproducibility and no limitation. With the continuous development of the technology, the limit photoelectric conversion efficiency of the crystalline silicon solar cell reaches 35%, and the conversion efficiency of the industrial crystalline silicon solar cell also reaches 18.5%. However, the existing efficiency is far from the existing requirement of human beings.
At present, the efficiency of a photovoltaic module is improved mainly in two aspects, one is the performance improvement of a cell, such as a perc double-sided cell, a heterojunction cell, a multi-junction cell and the like in the cell industry, but the improvement technology on the cell meets a certain bottleneck and is slowly developed. Another method for improving the efficiency of the photovoltaic module is to improve the packaging adhesive film. The existing synergistic solar cell packaging adhesive film mainly comprises two types, one is white EVA, the use of the white EVA provides a more excellent reflectivity for the module, and meanwhile, the white EVA is directly used on the back layer to replace the original transparent adhesive film, so that more effective reflected light can be provided to a certain extent. However, the use of whitening agents such as titanium dioxide reduces the adaptability of the material, and at the same time, the effective reflection amount provided by the whitening agents is also small, and the power improvement is limited. The other is a light conversion packaging adhesive film, and the principle of the light conversion packaging adhesive film is mainly that a fluorescent conversion agent is used for absorbing ultraviolet band sunlight with low utilization rate of a battery piece in sunlight and then emitting sunlight with visible light band, so that the utilization rate of the assembly to the sunlight is improved, and the efficiency of the assembly is further improved. However, the conventional light conversion agent is a fluorescent light conversion agent, which is easily hydrolyzed during long-term use to inactivate the conversion agent and cause synergistic failure, and the anti-aging capability is general, and the requirement for mass production is not realistic due to the expensive cost.
The important reasons influencing the generating efficiency of the assembly in the whole process from the irradiation of sunlight on the surface of the cell to the generation of the photoelectric effect of the cell are as follows: in the process that sunlight passes through glass and a packaging adhesive film, due to the Compton effect, the photothermal effect, the Wien scattering and the like, partial photon energy is transmitted to a medium material, and the energy attenuation of the sunlight is caused. Therefore, reducing the energy consumption in the above process will provide a feasible new solution for the efficiency improvement of the solar module.
