Condensation photovoltaic module with hollow glass packaging structure

Abstract

The invention provides a condensation photovoltaic module with a hollow glass packaging structure. The photovoltaic module with the hollow glass packaging structure comprises a condensing lens panel, a condensing lens which is placed on the condensing lens panel, a circuit base plate which is sticked with a solar battery, a terminal box which is placed at the back of the photovoltaic module. The condensing lens panel is packed with the circuit base plate through a hollow aluminum spacer and a hot melting butyl rubber which is placed on the hollow aluminum spacer. The internal hollow aluminum spacer is filled with molecular sieve. Frame around the photovoltaic module is filled with silicone adhesive to seal and splice edges. The condensation photovoltaic module with the hollow glass packaging structure can effectively absorb hydrone in an interlayer in air, can prevent circuit element from being corroded, and can protect the photovoltaic module well. In addition, the condensation photovoltaic module can prevent service life of the photovoltaic module from being influenced by temperature difference causing pressure difference between the inside of the photovoltaic module and the outside of the photovoltaic module, reduce shape change of the condensing lens panel, and ensure stability of a condensation photovoltaic module system and photoelectric conversion efficiency.

Description

technical field [0001] The invention relates to the field of solar photovoltaic technology, in particular to a concentrated photovoltaic module with a hollow glass encapsulation structure. Background technique [0002] At present, problems such as energy shortage, environmental pollution and greenhouse effect have seriously affected the survival and development of human beings. The development of new energy and renewable clean energy has become a common issue facing the world today. In the field of new energy research and development, solar photovoltaic power generation technology has undoubtedly attracted much attention. At present, due to the low photoelectric conversion efficiency of flat-panel photovoltaic power generation technology and the high price of corresponding silicon materials, it is difficult for its power generation cost to compete with traditional thermal power generation. As a high-efficiency and low-cost solar power generation technology, concentrating ph...

Problems solved by technology

However, different from flat-panel photovoltaic modules 25, CPV modules have higher requirements on packaging quality, because their packaging not only involves the waterproof, dustproof and insulation performance of the entire module, but also directly affects the optical system of the module.

Under this packaging structure of the CPV module, due to the large middle spacer layer, the interior is filled with a large number of air and water molecules. Under the influence of a large temperature difference, the internal water molecules will inevitably condense, thereby affecting the circuit of the CPV module. Components cause corrosion. In addition, the change of air pressure inside the spacer layer with temperature will also affect the light-gathering path and service life of the components. The higher requirements for packaging quality also directly affect the efficiency of mass production of CPV components.
