LONGi Green Energy has applied for a patent related to photovoltaic modules and systems, aiming to reduce delamination risks and extend their lifespan. According to information from the State Intellectual Property Office, the application, titled “A Photovoltaic Module and Photovoltaic System“, was filed on December 2024, with the publication number CN119947265A.
The patent abstract reveals that the photovoltaic module consists of:
1. **Solar Cells**: Each solar cell has a first surface and a second surface.
2. **Interconnection Components**: Multiple solar cells are connected in series via interconnection components.
3. **First Adhesive Layer**: This layer is applied to the first surface of the solar cell, positioned on the side of the interconnection components that faces away from the cell.
4. **Second Adhesive Layer**: This is laid on the second surface of the solar cell, also on the side facing away from the interconnection components.
Crucially, the peeling force between the second adhesive layer and the solar cell is greater than that between the first adhesive layer and the solar cell. This design enhances the bonding strength of the second adhesive layer, making it more secure. Consequently, even under the influence of gravity over prolonged use, the occurrence of delamination in the second adhesive layer is minimized, effectively reducing delamination risks and thereby extending the operational life of the photovoltaic module.
According to Tianyancha, LONGi Green Energy Technology Co., Ltd., established in 2000 and based in Xi’an, primarily engages in wholesale operations. The company has a registered capital of approximately 757.8 million RMB. Data analysis reveals that LONGi Green Energy has invested in 34 companies and has participated in 329 bidding projects. It holds 205 trademark registrations and 1,954 patents, along with 54 administrative licenses.
