Anti-PID heat conduction glue film, photovoltaic assembly and photovoltaic power generation system

Abstract

The invention relates to an anti-PID heat conduction glue film, a photovoltaic assembly and a photovoltaic power generation system, and belongs to the technical field of photovoltaics. The anti-PID heat conduction glue film comprises a glue film body and core-shell particles doped in the glue film body; each core-shell particle comprises an insulation inorganic heat conduction material inner coreand a protection outer shell coated at the outer surface of the insulation inorganic heat conduction material inner core. The photovoltaic assembly comprises the anti-PID heat conduction glue film; the anti-PID heat conduction glue film is bonded between a backboard of the photovoltaic assembly and a battery of the photovoltaic assembly. The photovoltaic power generation system comprises a plurality of photovoltaic assemblies in series connection and / or parallel connection arrangement. Insulation and heat conduction core-shell particles are doped in the glue film body and can be stably dispersed in the glue film for a long time. When the photovoltaic assembly is locally shielded or works at high irradiation, the core-shell particles can realize fast heat absorption or heat radiation; the battery temperature is reduced; the assembly output power is improved. Meanwhile, the core-shell particles have good insulation performance; the current passage channel can be isolated; the volume resistivity of the glue film is improved; the anti-PID performance of the assembly is greatly improved.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to an anti-PID heat-conducting adhesive film, a photovoltaic module and a photovoltaic power generation system. Background technique [0002] In order to curb pollution and develop green energy, photovoltaic technology has developed rapidly in recent years. However, the high cost of electricity is still the main factor restricting photovoltaics from occupying the mainstream energy market. [0003] At present, the commonly used efficiency improvement methods include stacking technologies such as PERC, PERT, double-sided, multi-busbar, large-size silicon wafers, reflective ribbons, and white EVA, which lead to a substantial increase in the power of a single module. However, the higher the power of conventional series modules, on the one hand, the temperature of the modules will continue to increase during operation, and the power of the modules has an inverse linear relationshi...
