Profile for forming solar photovoltaic component border

Abstract

The invention discloses a profile for forming a solar photovoltaic component border. The profile can stabilize the photoelectric conversion efficiency of a solar photovoltaic component. The inner side of the profile is provided with a bayonet for arranging a solar cell component, and the downsun surface of the profile is a mounting surface. A mounting cavity is formed between the mounting surface and the bayonet. At least one air vent is formed on the sunny surface of the profile, and is communicated with the mounting cavity. When the solar photovoltaic component border formed by the profile provided by the invention is used, heat on the back of the solar cell component can be smoothly discharged by the air vent without causing the continuous rising of temperature of the solar cell component, thereby ensuring the photoelectric conversion efficiency of the solar cell component.

Description

technical field [0001] The invention relates to a profile used to form a frame of a solar photovoltaic module. Background technique [0002] Solar photovoltaic modules usually include solar cell components and frames. Solar cell components are generally composed of five layers of tempered glass, EVA layer, solar cell, EVA layer and back sheet. They are combined by a laminator; in order to improve the solar cell The strength of the module makes it easy to transport and install. Usually, the solar cell module is packaged with an aluminum frame around it. The aluminum frame is composed of several profiles that are fixedly connected. For example, a rectangular aluminum frame is composed of four profiles that are fixedly connected. The structure of the profile currently used to form the frame of the solar photovoltaic module is: a bayonet for installing the solar cell module is provided on the inner side of the profile, a reinforcing rib is provided in the profile, and the back s...

Problems solved by technology

[0003] During the use of solar cell modules, they will generate heat due to sunlight, and a certain amount of heat will be generated inside, which will increase the temperature of the cells and reduce the photoelectric conversion efficiency; large-scale photovoltaic power generation such as building walls or photovoltaic curtain walls In the system, especially the photovoltaic power generation system combined with the building, most of the solar photovoltaic modules are used side by side, and they are closely connected with each other; and because the installation cavity of the profile forming the frame of the module is isolated from the sunny side, resulting in solar cell modules The heat on the back cannot be dissipated smoothly, resulting in the continuous rise of the temperature of the components, which greatly reduces the photoelectric conversion efficiency of photovoltaic components and photovoltaic power generation systems
