Problems solved by technology

At present, with the advent of double-sided cells, the back of photovoltaic modules can also generate electricity, which greatly improves the power generation capacity of modules and the cost of electricity per kilowatt-hour. However, the traditional frame greatly blocks the back of the module, which not only reduces the efficiency of power generation on the back of the module, but also may cause hot spots. , leading to local heating of the components, increasing the risk of component failure

Embodiment Construction

[0021] The core of the present invention is to provide a photovoltaic frame. see figure 1 , figure 1 It is a structural schematic diagram of a photovoltaic frame in the prior art. In the prior art, in order to ensure that the photovoltaic frame can support the solar cells, a c-plane is usually arranged in the photovoltaic frame. However, due to the existence of the c-plane, the back of the solar cell will be greatly blocked, so that the photovoltaic frame in the prior art is not suitable for double-sided solar cells. The c-plane not only reduces the efficiency of power generation on the back of the module, but also may cause hot spots, leading to local heating of the module and increasing the risk of module failure.

[0022] And the photovoltaic frame of a kind of solar cell that the present invention provides, comprises mold cavity and the glue overflow groove that is fixedly connected with mold cavity; The wall is in direct contact with any side wall of the cavity to be ...

Abstract

The invention discloses a photovoltaic frame of a solar cell. The photovoltaic frame of the solar cell comprises a cavity and a glue overflow groove fixedly connected with the cavity. The glue overflow groove is positioned on the upper surface of the cavity, the section of the cavity is rectangular, the supporting wall of the glue overflow groove is directly in contact with any side wall of the cavity to be fixedly connected, and the other side wall of the cavity is connected with the end portion of the upper wall of the cavity and the end portion of the lower wall of the cavity; the width ofthe cavity is larger than the width of the upper wall of the glue overflow groove, and the width of the cavity is less than two times of the width of the upper wall of the glue overflow groove. Because the supporting wall of the glue overflow groove is directly in contact with any side wall of the cavity, and the other side wall of the cavity is connected with the end portion of the upper wall ofthe cavity and the end portion of the lower wall of the cavity, the photovoltaic frame has no c-surface design, so that the condition that the c-surface shields the back surface of the double-sided solar cell can be avoided; because the width of the cavity is larger than the width of the upper wall of the glue overflow groove and is smaller than two times of the width of the upper wall of the glueoverflow groove, the cavity cannot shield the back of the double-sided solar cell, thereby being suitable for the double-sided solar cell.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a photovoltaic frame of a solar cell. Background technique [0002] Photovoltaic power generation is a power generation method that directly converts sunlight energy into electrical energy. Because it uses renewable sunlight and does not cause environmental pollution during the power generation process, it is a green and environmentally friendly energy production method. At present, photovoltaic power generation has been widely concerned by countries all over the world and has developed into a new industry. [0003] Photovoltaic modules are the basic unit to realize the stable output of electric energy from photovoltaic power generation. At present, with the advent of double-sided cells, the back of the photovoltaic module can also generate electricity, which greatly improves the power generation capacity of the module and the cost of electricity. However, the traditional fr...
