Chinese manufacturer Jinko achieved a conversion efficiency of 24,79% for an N-type monocrystalline silicon cell. The company stated that the result, certified by the ISFH (German Institute for Solar Energy Research in Hamelin), is a world record for a large cell size.
According to Jinko, several technologies were applied for manufacturing, including passivating contacts, an advanced diffusion system, surface passivation and an advanced anti-reflection technique. Material upgrades have also been integrated into the cell process.
“The company has reached a fundamental milestone in R&D (Research and Development). Our commitment to technological innovation in silicon materials, cell manufacturing and module processing technologies has led to several world records in terms of solar cell and module efficiency,” said Dr. Jin Hao, Chief Technology Officer at Jinko.
According to the manufacturer, the solar cell was produced on a high-quality CZ mono-Si substrate, with a practical size of 267,72 cm².
Record breaking
Jinko broke its own previous record, set in January 2019, when it achieved 24,2% efficiency. At the time, the cell was based on its HOT design and featured TOPCon technology.
