Description
Technical Field
The invention relates to the field of solar cells, flexible solar cells and solar cell packaging materials, in particular to a high-waterproof flexible solar cell packaging material and a preparation method thereof.
Background
The large-scale solar power plant occupies a large land area, and in order to reduce the occupation of the land of a residential area, the solar power plant is mainly constructed in a remote area with deserted and cool land, but the long-distance electric energy transmission cost is very high. Because the land in the desert area is not worth money and has sufficient sunlight, the desert area is generally the first choice for the construction of solar power plants. In fact, the situation of the sea is similar to that of the desert, the land cannot be occupied, and no sunlight shelters such as buildings, mountains and the like are arranged on the periphery of the sea. The construction of solar power plants in the sea has not previously been considered, mainly because conventional solar cells do not withstand seawater corrosion. With the continuous development of new technologies in the field of solar cells, more and more experts are dedicated to the construction of large-scale solar power generation systems on the sea.
Coastal areas are developed economically, have dense population and limited land resources, and cannot meet the construction of large-scale solar power plants. However, if the solar power plant is built on the sea, precious land resources are not occupied, remote power transmission from a remote area is not needed, the power cost is low, and the energy waste is less. Moreover, the solar power plant is directly built on the sea, can be directly cleaned and cooled by seawater, is convenient and has low cleaning and cooling cost. In summary, the construction of a solar power station on the sea has many advantages, but there are many problems to be solved, such as seawater corrosion resistance, prevention of the massive growth of algae on the surface of the cell, and protection against electric leakage, and therefore, there are higher requirements for solar cell packaging materials, packaging structures, packaging processes, and the like. In addition, the problem of load is also required to be considered in marine installation, and the battery is inconvenient to install and maintain due to the fact that the battery is too heavy in a double-glass packaging mode, so that a portable flexible solar battery is more suitable for a marine solar power plant.

Compared with the traditional transparent solar cell packaging material, the high-waterproof solar cell packaging material has better waterproof performance, can effectively resist the corrosion of seawater, and can be applied to the packaging of offshore flexible solar cells, thereby realizing the construction of offshore large-scale solar power plants.
