Abstract

The invention provides a novel flexible solar cell panel structure and a manufacturing method thereof. The novel flexible solar cell panel structure is characterized in that a traditional hard solar cell panel is cut into cell surface elements with the maximum width being not more than the designed minimum bending curvature radius, and flexible materials are used for connecting the cell surface elements from the side faces so as to obtain the flexible composite solar cell panel. The obtained flexible solar cell panel can be bent at will within the range being not less than the designed bending curvature radius, is foldable, and has high photoelectric conversion efficiency, and the efficiency of the flexible solar cell panel can reach or approach to the efficiency of hard solar cell panels of the same kind.

Description

technical field [0001] The invention belongs to the field of solar cells, and in particular relates to the design and preparation technology of a flexible solar cell panel with high photoelectric conversion efficiency and large-scale bending. Background technique [0002] Common solar panels can be divided into two categories: inorganic and organic materials. Inorganic materials, such as monocrystalline silicon and polycrystalline silicon, have the characteristics of high photoelectric conversion efficiency and good weather resistance, while the main advantage of organic materials is reflected in their flexibility and bending, so that they can be used in many special occasions, such as non-planar devices, portable equipment, etc. . But the photoelectric conversion efficiency of organic materials is low, and the service life is short. Flexible solar devices with high photoelectric conversion efficiency have attracted great attention. At present, there is a practice of evap...
