This article focuses on the photovoltaic junction box, a critical yet often overlooked component in PV modules. It elaborates on the box's dual role of current transmission and module protection, particularly its function in mitigating the hot spot effect via bypass diodes. The text emphasizes the superiority of Schottky diodes for their low power loss and fast switching. It outlines rigorous reliability verification processes ensuring long-term (25-year) stability. Looking ahead, the industry trends point to high-power, highly weather-resistant designs, advancements in wide bandgap semiconductors (like SiC), and the evolution toward intelligent interconnection with real-time monitoring capabilities. Finally, it highlights Sanders Microelectronics' (SMC) high-performance power semiconductor products as key enablers for next-generation PV junction box solutions. Read More

Against deepening power market reform and China’s "dual carbon" goals, Documents No. 4 (Guo Ban Fa〔2026〕) and No. 136 shifted China’s PV industry to bidding-based grid access, replacing fixed tariffs. The high-energy-consuming logistics industry faces the "impossible triangle" of cost reduction, carbon emission reduction and development. TCL PV Technology’s 11.79MW Feixi Logistics Park project, with an "full investment + 25-year trusteeship" model, offers a replicable "PV + Logistics" solution, verifying new energy’s integration path and driving PV enterprises’ transformation.
