PV ribbon is an important component of every mainstream solar panel, used to interconnect solar cells and provide connections to junction boxes. As we know, PV ribbon is a tinned copper strip, 1-6 mm wide and 0.08-0.5 mm thick, with a 10-30 μm thick solder coating. The quality of PV ribbon and its soldering to…
PV ribbon performance indicators are all important in their own right. The type of copper and its purity determine the electrical conductivity of the material and the maximum degree of flexibility that can be achieved with the ribbon. 1. Innovations in PV ribbon substrates Rayson is original in using CCA instead of copper as the…
PV Ribbon is an important raw material in the welding process of photovoltaic modules. The quality of the PV ribbon will directly affect the collection efficiency of the PV mould current, which has a great impact on the power of the PV module. How to choose PV ribbon? The PV ribbon must be welded firmly…
With the deep adjustment of the world’s energy structure, the global step into the decarbonization cycle. Global energy is accelerating the transition to the direction of high efficiency, clean and diversified. The development of clean energy has become an important factor affecting the global economy and ecological environment. Photovoltaic solar energy is clean, low-carbon, and…
The tab is a metal conductor that is drawn from the positive and negative collectors of the battery and is connected to the battery case (cylindrical/square) or to an external module structure (soft pack), and the current must flow through the tab to connect to the outside of the battery. Usually, we divide the battery…
How are lithium-ion safety features achieved? a. The diaphragm iautomatically shut off protection at 135°C, and the internationally advanced Celgars2300PE-PP-PE three-layer composite film is used. When the temperature of the battery reaches 120 °C, the membrane pores on both sides of the PE composite film are closed, the internal resistance of the battery increases and…
Battery tabs are a component of lithium-ion polymer battery products. Usually, we divide the battery into positive and negative electrodes. And the tab is the metal conductor that leads the positive and negative electrodes from the battery cell. Commonly speaking, the positive and negative battery tabs are the contact points when charging and discharging. The…
Flat wire motors generally adopt 4 or 8 layers of flat wire structure, and each process can be produced fully automatically by proprietary equipment. The product consistency is good and the production efficiency is high. However, the requirement for equipment specificity is high. And the economic type is not suitable for small batch production of…
