Based on n-type material PERL cells have a long life expectancy and achieve an efficiency potential of 25 %. Combined with the per se bifaciality of this cell architecture up to 40 % higher energy harvest in PV installations can be achieved. The simple manufacturing process based on the SCHMID co-diffusion leads to best of class conversion costs.

SCHMID’s PERL Bifacial Cell Technology:

• High efficiency by passivation on n-type mono material
• Bifacial concept featuring over 30 % more energy yield
• Just one temperature step for both phosphorus and boron deposition minimizes stress for the wafers
• Lowest process times
• Simple line configuration by proven equipment
• Transparent back-sheet or glass on module rear side
• Same cost of ownership as for PERC cells

• Efficiency potential of 25 %
• Greatly reduced recombination
• n-type for long durability
• Bifacial technology for higher energy harvest
• Smart process sequence with proven production equipment
