Abstract

The invention discloses a photovoltaic module structure and a processing technology, and relates to the field of photovoltaic modules.The photovoltaic module comprises a first frame and a second frame which are both made of copper, a chip, a jumper wire and a packaging body which is used for protecting and sealing the chip and the jumper wire, and the right end of the first frame is provided with a first protrusion, and the right end of the second frame is provided with a second protrusion; a second protrusion is correspondingly arranged at the left end of the second frame, and the chip is arranged on the second protrusion. The processing technology of the photovoltaic module comprises six steps. According to the invention, the problem that metal and nonmetal generate transverse shear force due to environmental changes such as external humidity and temperature when the existing photovoltaic module works can be solved; meanwhile, the problems that heat generated by electron movement in the working process of the chip cannot be fully dissipated, the effect is poor, and the photovoltaic module is short in service life, high in cost, prone to packaging failure and inconvenient to assemble subsequently are solved.

Description

technical field [0001] The invention relates to the field of photovoltaic modules, in particular to a photovoltaic module structure and processing technology. Background technique [0002] Photovoltaic bypass diode module is a kind of photovoltaic module. The solar cell power generation system includes a number of solar cell components. During the power generation process of the solar cell components, if there is a hot spot effect, the shaded solar cell components will generate heat and consume electric energy, and the hot spot effect will seriously damage the solar cells. When the hot spot effect occurs, the photovoltaic module is turned on, the current generated by the solar cell components that are normally generating electricity flows out through the photovoltaic module, the solar cell components that are shaded are short-circuited, and the solar cell power generation system generates electricity normally, avoiding the occurrence of There is a problem with some solar ce...
