China's solar energy giant LONGi announced on Friday that it has set a new world record of 33.9 percent for the efficiency of crystalline silicon-perovskite tandem solar cells, indicating that China is once again leading the world in the field of solar cells due to its green development push.
"This is the first time in the history of the PV industry that a Chinese solar technology company has set the world record for silicon solar cell efficiency," Martin Green, a professor at the University of New South Wales in Australia, who is known as the "Father of PVs," said on Saturday, according to an announcement sent to the Global Times.
"China's photovoltaic products, including polysilicon and solar power modules, account for more than 80 percent of the global share.
The conversion efficiency of photovoltaic (PV) cells refers to the ability of cells to convert solar power into electric energy. The more electricity cells can generate from the same area while absorbing the same amount of light, the better.
A Japanese company set the previous PV efficiency record at 26.7 percent in 2017. "Solar cell efficiency is the beacon of PV technology innovation. Every 0.01-percent improvement in solar cell conversion efficiency requires enormous efforts.
With the improvement of cell efficiency, China's solar power products will become more competitive in the global market, which will also contribute more scientific and technological power to the achievement of the dual-carbon goal of the world," Xu Xixiang, chief scientist of LONGi, told the Global Times on Friday.
