Abstract

The invention discloses an intelligent photovoltaic module internally provided with a chip. The intelligent photovoltaic module comprises tempered glass, EVA layers, a back plate and a solar cell slice layer. The two sides of the solar cell slice layer are provided with the EVA layers. The sides, away from the solar cell slice layer, of the two EVA layers are provided with the tempered glass and the back plate respectively. The intelligent photovoltaic module further comprises the intelligent chip and a split wiring leading-out terminal without diodes, wherein the intelligent chip is arranged on the side, close to the tempered glass, of the solar cell slice layer, and the split wiring leading-out terminal is arranged on the side, away from the EVA layers, of the back plate. The solar cell slice layer is provided with at least one solar cell slice. According to the intelligent photovoltaic module, the intelligent semiconductor chip is used for being packaged inside the photovoltaic module, cell cascade-stage MPPT optimization is carried out, the maximum power output obtained when the module is shielded is improved, and meanwhile the reliability of the module is improved.

Description

technical field [0001] The invention relates to a photovoltaic component, in particular to a smart photovoltaic component with a built-in chip. Background technique [0002] At present, the existing crystalline silicon photovoltaic modules use photovoltaic junction boxes with Schottky diodes. When the glass surface of the components is blocked to a certain extent, the reverse biased diodes are turned on and start to work, resulting in partial battery strings being short-circuited, and the components The power output of the module decreases proportionally, and the power generation capacity is greatly reduced. At the same time, the shaded cells and corresponding working diodes will generate a lot of heat, resulting in a great risk of failure of the module cells and diodes. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to solve the problem that the existing photovoltaic modules are prone to short-circuit of the battery st...
