What is MWT backsplice technology for solar panels?

Solar panel MWTbackbonding is a solar module manufacturing technology that uses laser drilling and backside wiring to eliminate the main grid lines on the front side of the cell, and metal is printed into these through holes/holes and burned into the cell so that the resulting current can be extracted from the backside of the emitter and contact areas (positive and negative electrodes), a technology currently only used in crystalline silicon solar cell wafers

Traditional solar modules usually use aluminum electrodes on the front side to collect current, while MWT back bonding moves the current collection electrodes to the back side to reduce the blocking area of the front electrodes and improve light absorption efficiency. By perforating a hole between the front and back electrodes, current can be collected and transmitted more efficiently through the back electrodes, thus increasing the conversion efficiency of the solar cell.

MWT back-joining technology also offers other advantages, such as reduced current transmission losses, improved cell reliability and durability, and reduced thermal resistance. Therefore, MWT backbonding technology is widely used in the field of solar cell module manufacturing to improve the performance and efficiency of solar cells.
