Abstract

The invention provides a structure of an ultra-thin crystal-silicon solar battery pack, comprising a back plate; the back plate is provided with an EVA adhesive film in a laying manner; solar battery plates are arranged in the EVA adhesive film at intervals and are connected by photovoltaic welding strips; and the EVA adhesive film is provided with a surface cover plate in a laying manner. The reinforcing rib strips are individual components laid between the back plate and the surface plate. The structure of the invention is characterized in that reinforcing rib strips are arranged between the back plate and the surface cover and in interval regions among the solar battery plates. The invention also provides a packaging method of the structure. As the reinforcing rib strips are laid on the structure, the back plate and the surface plate can be prepared by lighter materials, but the whole structure strength can not be reduced. The structure of the ultra-thin crystal-silicon solar battery pack and the packing method of thereof of the invention not only can be applied in construction of photovoltaic power stations, and have larger advantages and application prospects in the field of photovoltaic application products, especially the field of portable photovoltaic power supplies.

Description

technical field [0001] The invention belongs to the field of solar cell processing, and in particular relates to a structure of an ultra-thin solar cell module and a packaging method thereof. Background technique [0002] Traditional fuel energy is decreasing day by day, and the damage to the environment is becoming more and more prominent. At the same time, there are still 2 billion people in the world who do not have normal energy supply. At this time, the whole world is turning its attention to renewable energy, hoping that renewable energy can change the energy structure of mankind and maintain long-term sustainable development. Among them, solar energy has become the focus of attention due to its unique advantages. Abundant solar radiation energy is an important energy source, which is inexhaustible, non-polluting, cheap, and can be freely utilized by human beings. How to efficiently convert solar energy into disposable energy is a subject that experts from various co...
