The manufacturer in Ontario broke its record.

Solar panel maker Canadian Solar said its p-type polysilicon P5 solar cells have an efficiency of 22.8%. The company said the new record has been confirmed by the German Solar Energy Research Institute and exceeded the previous record of 22.28% set by the manufacturer at the end of May.

“I am very pleased to announce that we have once again broken the world record,” said Shawn Qu, CEO of Canadian Solar. “This is a milestone in the development of our P5 technology. It demonstrates that our polysilicon technology can achieve very close to single crystal efficiency while still enjoying the cost advantages of polycrystalline.”

The company added that the new record is achieved with 157 square millimeters of P5 silicon plus metal catalyzed chemical etching ("black silicon" process); selective emitter technology; multilayer anti-reflective coating; advanced surface blunt And optimized grid design and metallization.

Mono

This type of solar cell is produced using seed crystal silicon (also known as cast single crystal silicon or quasi-single crystal silicon). The cast single crystal process can produce "single crystal" wafer materials using an improved polycrystalline furnace and avoids the expensive investment in the spindle. Cast single crystal wafers are less susceptible to recombination due to boron oxide defects and have the advantage of lower photodegradation.

Competitor manufacturer GCL Systems Integration launched a module based on cast mono technology last spring with an efficiency of 18.9%.

Mold manufacturing began to appear at the beginning of this century, but disappeared due to the lack of production lines. However, as more efficient single-crystal panels exceed industry standards, polycrystalline producers have begun to adopt single-crystal casting technology, thereby avoiding the cost of restructuring their production capacity.
