Photovoltaic module

Abstract

The invention discloses a photovoltaic module applied to new technologies. The photovoltaic module comprises a junction box and a lamination layer, wherein the lamination layer sequentially comprises the following components from top to bottom: a front plate tempered glass matrix capable of absorbing or reflecting infrared light and ultraviolet light or light with other wavebands, a front plate tempered glass textured suede, a packaging layer with an UV (ultraviolet) absorption or transmission function, a back plate tempered glass matrix, and a heat dissipation film layer; a crystalline silicon battery is arranged in the packaging layer, and a reflective function film layer is plated on the inner surface of the back plate tempered glass; an aluminium alloy border is installed at the periphery of the lamination layer composed of the layers above. The photovoltaic module disclosed by the invention is reasonable in structure; the internal temperature of the module can be effectively reduced, the output power of the module can be increased, and the service life of the module can be prolonged.

Description

technical field [0001] The invention relates to a backplane technology applied to a photovoltaic module, in particular to a brand-new improvement to the conventional crystalline silicon photovoltaic module, and belongs to the field of photovoltaic technology. Background technique [0002] Photovoltaic modules are the core components of photovoltaic power generation applications. According to the inventor's understanding, the front glass of the double-glass photovoltaic module produced industrially at home and abroad does not have the excellent characteristics of absorbing or reflecting infrared light or ultraviolet light, which will cause the temperature inside the module to rise, thereby resulting in the output power of the module and The service life is reduced, and the back glass is transparent or translucent, which will directly transmit the light from the back plate, so that the battery cannot fully absorb and utilize the reflected light of the back glass, thereby affec...

According to the inventor's understanding, the front glass of the double-glass photovoltaic module produced industrially at home and abroad does not have the excellent characteristics of absorbing or reflecting infrared light or ultraviolet light, which will cause the temperature inside the module to rise, thereby resulting in the output power of the module and The service life is reduced, and the back glass is transparent or translucent, which will directly transmit the light from the back plate, so that the battery cannot fully absorb and utilize the reflected light of the back glass, thereby affecting the output power of the photovoltaic module. At the same time, Since the outer surface of the backplane glass of the conventional double-glass photovoltaic module has no heat dissipation layer structure, the temperature of the module cannot be effectively dissipated, resulting in the inability to effectively reduce the temperature of the module, thereby affecting the heat dissipation performance of the module, and further affecting the double-glass photovoltaic module. At the same time, the glass thickness of conventional double-glass modules is relatively thick, heavy, and difficult to carry. The conventional plastic junction box is used, which may easily cause high internal temperature of the junction box and damage the service life of internal components, thereby affecting the life of the module. service life
