Foldable photovoltaic module and manufacturing method thereof

Abstract

The invention relates to a foldable photovoltaic module and a manufacturing method thereof. The foldable photovoltaic module comprises a bottom cloth, a window cloth and photovoltaic cell structures,wherein a plurality of openable windows are arranged neatly on the window cloth; a plurality of photovoltaic cell structures are arranged between the bottom cloth and the window cloth and are corresponding to the positions of the windows; the plurality of photovoltaic cell structures are provided with flexible circuit boards; series connection, parallel connection or series-parallel hybrid connection among the photovoltaic cell structures can be realized through flexible wires connected with the flexible circuit boards; the transverse flexible circuit boards are arranged in a spaced mode at the top sides and the bottom sides of the photovoltaic cell structures; the longitudinal flexible circuit boards are arranged in the middle sections of the bottom or the top of the photovoltaic cell structures; and the transverse flexible circuit boards and the longitudinal flexible circuit boards are not simultaneously arranged at the bottom or the top of the photovoltaic cell structures. The foldable photovoltaic module has the advantages that folding is facilitated; the size is small; the weight is light; carrying is facilitated; and four corners of the bottom and the window cloth of the foldable photovoltaic module are provided with through holes, the foldable photovoltaic module is suspended through ropes and can be unfolded to realize absorption of solar energy.

Description

technical field [0001] The invention relates to the technical field of photovoltaic products, in particular to a foldable photovoltaic module and a manufacturing method thereof. Background technique [0002] Solar cells are widely used in communication satellite power supply, off-grid power generation systems, grid-connected power generation systems and other fields, mainly including crystalline silicon cells, thin-film cells and other new types of cells. The crystalline silicon battery module used for solar power generation is a photovoltaic power generation system in which crystalline silicon solar cells are arranged in a certain form and electrically connected, and then laminated together with packaging materials such as glass, sealant, and backplane. product. This component product is relatively heavy in quality, large in size, and inconvenient to carry. In some cases where portable electronic equipment is used, such as field exploration equipment, field communication ...

Problems solved by technology

This kind of component product is relatively heavy in quality, large in size, and not easy to carry

In some cases where portable electronic equipment is used, such as field exploration equipment, field communication equipment, field investigation equipment, field entertainment equipment, etc., a portable photovoltaic power supply is required to power it anytime and anywhere. However, as we all know, crystalline silicon cells The bending rate is small and brittle, so it cannot be made into flexible products
