Jinko asserts 24.79% performance for n-type monocrystalline cell
- The Chinese producer has actually declared a world document for a large-size, contact-passivated solar cell. The result, certified by Germany's Institute for Solar Energy Research in Hamelin, betters the company's previous document by almost 0.6%.
Chinese solar maker JinkoSolar has accomplished 24.79% conversion efficiency for an n-type, TOPCon, monocrystalline-silicon cell.
The firm states the outcome, certified by Germany's Institute for Solar Energy Research in Hamelin, is a globe document for a large-size, contact-passivated cell. Jinko damaged its own document in January, when it struck 24.2% efficiency.
In May 2018, Jinko's ideal tool had actually a reported efficiency of 23.95%, up from the 23.45% recorded in November 2017. Those sites were both accredited by the Photovoltaic as well as Wind Power Systems Quality Test Center at the Chinese Academy of Sciences.
The most up to date Jinko cell includes a 267.72 cm2 monocrystalline silicon substratum grown making use of the Czochralski technique.
The producer said it had actually applied a number of modern technologies to obtain the result, including passivating get in touches with, an innovative diffusion system, surface area passivation and an advanced anti-reflection method. Material upgrades were also incorporated right into the cell process, stated Jinko. "The record-breaking monocrystalline silicon solar cell will be progressively applied to item production," claimed the company.
In January, Jinko said its cell was based on its HOT design and included tunnel-oxide passivating get in touch with (TOPCon) modern technology.
