The team addresses the following subjects to develop technologies for producing low-cost, highly efficient and reliable modules (target conversion efficiency: 22%)
Silicon ingot slicing technology with high accuracy and reproducibility (thin wafer)
High efficiency cell fabrication technique using thin Si wafers (PERC cell, Back contact cell etc.)
Technologies for improving the efficiency and reliability of PV modules (development of new materials, structures, etc.)
The team is also focusing on the research of “smart stack technology” to develop a next-generation highly efficient solar cells (conversion efficiency higher than 30%). The technologies to achieve the power generation cost target of 14 JPY/kWh in 2020 and 7 JPY/kWh by 2030 will be developed.
