Description

technical field [0001] The invention relates to the technical field of solar photovoltaic components, in particular to a BIPV smart chip photovoltaic component and its packaging process. Background technique [0002] Conventional crystalline silicon photovoltaic modules are installed on various facades or facades with different angles. Due to the uneven radiation received by the surface of each module, the power generation of the system will decrease. [0003] Photovoltaic modules are composed of certain specifications and quantities of solar cells combined in series and parallel and packaged together. Since the current and voltage of a single solar cell are very small, we first connect them in series to obtain a high voltage, and then connect them in parallel to obtain a high current, and then output it through an anti-backflow diode. Conventional photovoltaic modules are connected using junction boxes with bypass diodes. The disadvantage is that once the hot spots are cau...

AI Technical Summary

Problems solved by technology

Conventional photovoltaic modules are connected using junction boxes with bypass diodes. The disadvantage is that once the hot spots are caused by shading or defects in the battery itself, the bypass diodes will start, and the battery strings corresponding to the diodes will be short-circuited, and the output power of the modules will drop by at least 1 / 3. At the same time, the system is prone to problems such as current and voltage mismatch, hot spots, shading, and dust occlusion, resulting in a decrease in power generation of the entire system

[0004] With the advancement of technology, the development of photovoltaic power plants in the future must develop in the direction of intelligence, and the intelligentization of power stations must first realize the intelligence of components. At present, the more common smart photovoltaic modules are photovoltaic modules with smart junction boxes. Through Glue the smart junction box behind the ordinary components, realize MPPT in the battery slice cascading level, and reduce LCOE, but because of the intelligent optimization at the electrical device level, the reliability depends on the life of the electrical components, and it is exposed to the atmospheric environment, so the reliability is poor ; At the same time, the loss of components is large, resulting in low efficiency of components
