Description
Technical Field
The utility model relates to an impact-resistant transparent packaging front plate and a photovoltaic module, and belongs to the technical field of photovoltaics.
Background
In the photovoltaic field, the transparent packaging material used by the prior double-sided component or single-sided component mainly comprises glass, but the glass is heavy and thick and has no bending effect, so that the development requirement of the future photovoltaic component cannot be met; the conventional high polymer material front plate at present is difficult to meet the corresponding test standard requirements in terms of impact resistance.
In order to meet the use requirements of distributed photovoltaics, light flexible components have increasingly stringent requirements for packaging materials.
In the research of light flexible component packaging materials, light transmittance is a basic requirement for ensuring power output, and the use environment of the front plate is required to have good impact resistance, and the impact resistance of some current transparent polymer front plates has a great hidden trouble.
At present, the common polymer packaging material cannot meet the hail resistance experiment related to the impact resistance capability in the latest IEC standard due to the characteristics of the structure of the common polymer packaging material. For example: CN 215184007U proposes a transparent front plate, which mainly solves the problems of heavy weight and brittleness of the existing photovoltaic cell assembly using glass as the front plate, and proposes to use a 550 μm polyester film as an impact resistant layer. However, the polyester film with larger thickness is difficult to obtain in the current production process, and the production cost of the polyester film with the thickness of 550 μm is difficult to be produced in batches in the market at present. And the product bonded by the multilayer polyester film has the risk of delamination caused by smaller interlayer peeling force, for example, CN 215184007U is bonded with double-sided PET by adopting glue, and the risk of delamination exists in the using process, so that the photovoltaic module can not be ensured to meet the requirement of 15 years of outdoor service.
In addition, when a single-layer fluororesin material is used for protecting the resin glass fiber layer, the layer is easy to cause yellowing and ageing problems under the ultraviolet ageing condition, and the power generation efficiency of subsequent components is affected. For example: CN 208835079U proposes a lightweight impact-resistant photovoltaic module, which is a lightweight impact-resistant photovoltaic module meeting high light transmittance, and the module mainly uses a resin glass fiber layer to improve the impact resistance of a front plate, but only uses a single-layer fluororesin material to protect the resin glass fiber layer, so that the resin glass fiber layer is easy to be subjected to ultraviolet irradiation to generate obvious yellowing, and the power generation efficiency of the subsequent module is affected.
