JinkoSolar says its N-type cell hits conversion efficiency record at 25.4%

Chinese solar module maker JinkoSolar Holding Co Ltd (NYSE:JKS) said it has made a technical breakthrough in the development of its N-type monocrystalline silicon solar cell, reaching a world record maximum solar conversion efficiency of 25.4%.

The company said the record result set by its large-size passivating contact solar cell had been independently confirmed by the Japan Electrical Safety and Environment Technology Laboratories (JET).

The cell was fabricated on a high-quality Czochralski (CZ) mono-Si substrate. JinkoSolar integrated ultra-fine line metallisation, advanced diffusion, low parasitic absorption material, its self-developed HOT technologies and a series of material upgrade into the cell process to achieve the 25.4% conversion efficiency.

Hao Jin, JinkoSolar’s chief technology officer, highlighted that the latest record is the company’s fourth within a year.

“We will continue to provide customers with the most LCOE-competitive products they need for large scale projects, and at the same time, this is a big milestone in our R&D capabilities to make clean energy affordable and sustainable for everyone,” Jin said.
