  • The difference between a light fuse and a non-light fuse

    A fuse is an electrical component used for circuit protection whose core function is to automatically fuse when the current exceeds the rated value, cutting off the circuit and thereby preventing equipment damage or fire risk. The fuse is usually composed of a metal fuse (or fuse) and an insulating shell, and when the current is abnormally high, the fuse melts due to overheating and breaks the circuit.

  • Efficiency Surpasses 30% & Module Power Exceeds 800W: China's PV Industry Enters the "Tandem Era"

    China's photovoltaic (PV) technological innovation witnessed a "boom period" in 2025: in late October, a joint research team from Nanjing University and the National Innovation Institute of Defense Technology achieved a breakthrough in all-perovskite tandem solar cell efficiency, reaching 30.1% and setting a new global record. Three months later, Trina Solar announced that its 210mm large-size perovskite-silicon tandem module had exceeded 800W in power, officially kicking off the industrialization process. This "dual breakthrough"—from basic scientific research to industrial application—marks China's PV industry is transitioning from "leading in scale" to a new stage of "technological dominance".
