Technology Introduction

Why choose daycare photovoltaic & MWT technology?
Suncare has fully independent intellectual property rights of MWT's high-efficiency back-contact battery and module technology, breaking through the technical bottleneck of the industry, and successfully achieving GW-level mass production of this technology product.
Compared with conventional products, MWT modules have no busbars, which reduces the front shading loss by 3%, and the use of conductive foil instead of welding ribbons avoids problems such as stress and micro cracks caused by high-temperature welding, and greatly improves the stability of the modules And reliability.
              Core structure
MWT
The positive and negative poles of the battery are located on the back of the battery


conventional
The positive and negative poles of the battery are located on the front and back of the battery respectively
- Battery structure -


MWT
There is no busbar on the surface of the battery, and the shading area is reduced by about 3%, providing higher output power.


conventional
The main grid line design on the front of the battery increases the shading area and reduces the output power.
- Encapsulation method -



MWT
It adopts a zero welding process, connects cells in series with conductive foil, and uses a planar two-dimensional package structure to reduce series resistance and component operating temperature and improve reliability.
 
conventional
The battery slices are connected in series up and down with the welding ribbon, high-temperature welding and the thickness of the welding ribbon will cause stress on the battery slices, causing cracks and affecting reliability.
