Recently, Solar Frontier, a subsidiary of Showa Shell Oil, increased the unit conversion rate of CIS-type solar cells to 22.
3%, breaking the record
of 21.
25% for polysilicon solar cell research and development products.
Although the module conversion efficiency of CIS-type solar cells is only about 13%, the company said that it will supply products with an efficiency of about 15% in 2016, and will be able to supply products with an efficiency of 16~17% before 2018, exceeding most polysilicon-based solar cells
.
According to Gou Kuritani, director and vice president and executive director of the company, the active layer of CIS-type solar cells has not changed
much from the past in terms of material and crystal quality, as well as manufacturing process.
What changes is only the thickness of the active layer, the composition and configuration
of the material.
High-efficiency monocrystalline silicon solar cells require high-precision patterning and ion implantation technologies, requiring expensive fabrication devices
.
Instead of relying on expensive installations and processes, the company used wisdom and experience to improve conversion efficiency
