Abstract

The invention discloses a photovoltaic module frame and a material thereof, and a photovoltaic module, relates to the technical field of solar photovoltaic modules, and aims to solve the problems that the PID effect of the photovoltaic module is caused and the generating capacity of the photovoltaic module is influenced due to the fact that water vapor permeates into the photovoltaic module. The photovoltaic module frame material comprises a thermoplastic polymer material, an inorganic fiber material and a dispersing agent. Specifically, the thermoplastic polymer material accounts for 64%-72% of the photovoltaic module frame material by mass percentage, the inorganic fiber material accounts for 24%-32% of the photovoltaic module frame material by mass percentage, and the dispersing agent accounts for 2.5%-4% of the photovoltaic module frame material by mass percentage. The photovoltaic module frame comprises the photovoltaic module frame material provided by the technical scheme. The photovoltaic module frame material provided by the invention is used for manufacturing the photovoltaic module frame.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic components, in particular to a photovoltaic component frame and its material, and a photovoltaic component. Background technique [0002] With the continuous development of the photovoltaic industry, the application range of solar photovoltaic modules has gradually increased. However, in a humid and high-temperature outdoor environment, water vapor is easily generated inside the photovoltaic module. When water vapor penetrates into the photovoltaic module, the conductivity of the packaging material will increase, which will increase the leakage current of the photovoltaic module, resulting in the PID of the photovoltaic module. effect, affecting the power generation of photovoltaic modules. [0003] At present, most of the photovoltaic modules on the market are designed with metal frames, and the inverter at the system side is generally positively grounded, and the modules in the array...
