Double-glass photovoltaic assembly

Abstract

The present invention is to provide a double-glass photovoltaic assembly and is to solve the technical problem that an existing double-glass photovoltaic assembly is easy to have a hot-spot effect, large in processing difficulty and high in cost. The double-glass photovoltaic assembly comprises a body and a junction box. The junction box has a first installation surface and a second installation surface. The first installation surface is attached to a backlight surface of the body; the second installation surface is attached to a bus bar leading-out side surface of the body; and the second installation surface does not exceed a light-receiving surface of the body. Two installation surfaces are provided to increase the contact area of the junction box and the body, thereby greatly improving installation reliability of the junction box; compared with the technology of punching or slotting in backboard glass, the double-glass photovoltaic assembly saves production cost, and solves the process problems, such as battery pressing crack and seal reliability and the like, in the assembly lamination process; and besides, the second installation surface does not exceed the light-receiving surface of the body, so that the hot-spot effect does not occur, and generating power and service life do not influenced.

Description

technical field [0001] The invention relates to the field of solar cell components, in particular to a double-glass photovoltaic component. Background technique [0002] Double-glass photovoltaic modules, also known as double-glass solar cell modules, have transparent glass plates on both sides of this photovoltaic module, and the cell array is encapsulated between the two glass plates. Since multiple double-glass photovoltaic modules can be combined into glass curtain walls of large buildings, double-glass photovoltaic modules have developed into a new type of building material in the construction industry. [0003] The double-glass photovoltaic module is composed of front glass, EVA film, cell array, EVA film, and back glass from the front to the back. After the cells are connected in series or in parallel, the electric energy generated by the battery string is transmitted to the junction box through the bus bar. On the terminal of the busbar, the busbar passes through be...

Problems solved by technology

Although this structure solves the problem of installation reliability, the opening or slotting of the back glass seriously increases the difficulty of the processing technology, resulting in a substantial increase in cost. Fracturing of medium cells

[0007] In view of the above problems, there is an urgent need to provide a new double-glass photovoltaic module to solve the existing problems in the prior art that are prone to hot spot effects, affect power generation and service life, and are difficult to process and high in cost.
