challenge solar panels It’s about becoming more and more efficientIn other words, they can convert more solar energy into electricity with the same panel surface. In this way, they can provide more service and it is also the way to reduce the size of the plates. It has now become clear that a new record was brokenApproaching 34% conversion efficiency.
Longi Green Energy Technology Co Ltd, one of the leading companies in the photovoltaic industry in China, broke the world record a few days ago with its new photovoltaic conversion efficiency. 33.9 percent for silicon-perovskite tandem solar cellsThis is the technology that makes this unusual use possible.
This is the highest efficiency rate in the world for a perovskite/silicon binary cell and also Approved by the United States National Renewable Energy Laboratory (NREL)According to the newspaper, it is affiliated with the Ministry of Energy ChinaDaily.
Thus, the world’s best tandem solar cells, currently consisting of a lower silicon cell and an upper perovskite cell, can already convert approximately one-third of incoming solar radiation into electrical energy. The previous record was set by the KAUST photovoltaics laboratory in Saudi Arabia in May, with 33.7 percent.
“An important indicator”
“Increasing cell conversion efficiency and reducing the cost of electricity continues to be the driving force behind the development of the photovoltaic industry. Photovoltaic conversion efficiency of solar cells is a very important indicator and criterion “to evaluate the potential of photovoltaic technologies,” Longi president Li Zhenguo said at a press conference presenting these results.
The dominant technology in the industry, with a market share of more than 90 percent, is monocrystalline silicon solar cells, but their conversion efficiency is currently approaching the theoretical efficiency limit of 29.4 percent. In its place, The theoretical efficiency limit of tandem solar cells consisting of monocrystalline silicon and perovskite materials is up to 43 percent.This means that with the same surface area and absorbing the same amount of light, these cells can produce more electricity.
Deputy secretary general Jiang Hua said at the press conference that the world record for solar cells achieved by Longi means that this company is now (and until it achieves another record) at the forefront of global research and development in this technology. China Photovoltaic Industry Association (CPIA).
reduce costs
“Cost reduction and efficiency improvement are at the heart of the photovoltaics industry. “Continuous improvement of the conversion efficiency of photovoltaic cells is an effective measure to reduce the overall cost of photovoltaic energy production,” he said.
“When this high-efficiency cell technology is truly mass produced, will lead to a significant reduction in photovoltaic energy production costs“This will be extremely beneficial in driving the growth of the photovoltaics market in China and globally,” he added.
The company has been investing heavily in research and development (R&D) in recent years and plans to continue investing in the development of the global photovoltaic industry through investment and technical cooperation to enable more companies to operate. announced that it is on the global stage.
