Risen Energy Co., Ltd. recently announced that its proprietary cast-mono 5BB 
cell has achieved an efficiency of 22.05 percent while its MBB monocrystalline 
cell has realized a maximum conversion efficiency of 23.08 percent and an 
average efficiency of 22.73 percent, marking another major milestone in the 
company's efforts to reduce costs and enhance efficiency. 

The enhancement in efficiency is the result of Risen Energy's constant 
innovation. The highly efficient cast-mono 5BB cell uses a series of latest 
efficiency enhancement technologies including double-sided passivation, 
antireflective films, electro-injection passivation and slurry improvement. 
This is the first time that a cast-mono 5BB cell has successfully exceeded 22 
percent in efficiency. 

Compared with the 5BB cell, the MBB monocrystalline cell features a more 
optimized metallized contact technology, which effectively reduces the shading 
area, enhances the ability to collect carriers while reducing the incidence of 
cracks, contributing to a significantly higher conversion efficiency. At the 
same time, a further cost reduction is realized with decreased use of silver 
slurry. 

Risen Energy said that the company has always been committed to raising the 
efficiency and reliability of its products while lowering costs, in an effort 
to improve the efficiency of its cell modules, optimize the structure of its 
cell components and enhance product quality. Keeping up with industry trends, 
Risen Energy will continue to focus on improving the quality and efficiency of 
its PV products through innovation in technology, in a move to accelerate grid 
parity. The company will also work with its strategic material suppliers to 
promote the development of new materials, in a move to better meet the need for 
more efficient cell technologies, creating more investment value for the 
application side.
