Canadian Solar insurance claims 23.81% performance for n-type poly module
- The Chinese-Canadian supplier claimed the brand-new outcomes surpass its previous document by around 1%. The success has actually been accredited by Germany's Institut für Solarenergieforschung GmbH (ISFH).
Canadian Solar has actually reported a 23.81% conversion effectiveness for a p-type multicrystalline P5 solar battery.
The Chinese-Canadian PV module supplier claimed the brand-new document has actually been validated by Germany's Institut für Solarenergieforschung GmbH. It complies with the business's previous document of 22.8%, embeded in September 2019.
"This is the 3rd time within a period of 9 months that the business has actually established a multicrystalline solar battery conversion effectiveness globe document," the business stated, without exposing exactly how it enhanced the performance of the cell.
The cell, which gauges in at 157mm x 157mm (246.44 cm2), is based upon n-type P5 silicon wafer and also PASCon (passivated get in touch with) innovation. In September, Canadian Solar stated that the enhancement of the cell's efficiency was accomplished with metal-catalyzed chemical etching, the "black silicon" procedure, careful emitter modern technology, a multilayer anti-reflective finishing, progressed surface area passivation, and also maximized grid layout as well as metallization.
Solar cells of this kind are created with seeded actors silicon, which is additionally called cast-mono or quasi-mono crystalline silicon. Via this procedure, the supplier can create mono-like wafer products utilizing a customized multicrystalline heating system to prevent expensive financial investments in ingot drawing equipment.
Cast-mono wafers are additionally much less vulnerable to recombination by boron-oxygen flaws. On top of that, they supply the benefit of reduced light-induced destruction.
