Alibaba Cloud ET Industrial Brain Next Step: Improve Solar Cell Efficiency

【Global Science and Technology Report】 Alibaba Cloud Artificial Intelligence is making a breakthrough in smart manufacturing. On April 26, at the Yunnan Summit of the Yunqi Conference, Trina Solar announced the introduction of the Alibaba Cloud ET industrial brain to find better production processes to increase the photoelectric conversion rate of the solar cells.

Can AI help silicon convert light into electricity? "ET industrial brains will enter into Trina Solar's real-time analysis of hundreds of millions of production data, find the best production model among the tens of thousands of production parameters, and ultimately increase the proportion of excellent battery cells." Aliyun Artificial Intelligence Scientist Wan Wanli said.

Compared with coal-fired power generation, photovoltaic power generation is green, environmentally friendly, and non-polluting. However, because of its high cost, it has not been able to be used on a large scale in China. Increasing the photoelectric conversion rate is an effective way to reduce costs. It is estimated that for each increase in the photoelectric conversion efficiency by 1 percentage point, the cost per degree of electricity can be reduced by 5%-7%.

According to Hua Minhong, president of Trina Solar's manufacturing division, in the photovoltaic industry driven by innovation, Trina Solar has been striving to improve the photoelectric conversion rate and system cost of batteries through technological breakthroughs and product updates. reduce. "We are looking forward to the performance of Alibaba Cloud's ET industry brain."

How does ET work? Wan Wanli introduced that ET will first transfer the data of all ports in the workshop to the industrial brain, and then use artificial intelligence algorithms to perform deep learning calculations on all related parameters, accurately analyze the most relevant key parameters of production quality, and build parameter curves. Real-time monitoring and control of variables in the production process, and ultimately the laboratory's R & D results in the precise production of large-scale production.

Trina Solar was founded in 1997 and is a leading global provider of solar energy solutions. As one of China's early solar companies listed on the NYSE, Trina Solar invested heavily in technology research and development. In terms of battery and module efficiency, it has cumulatively broken 15 world records.

“Global PV looks at China and China PV looks at Jiangsu.” Also in Jiangsu, last year ET entered the slicing production workshop of domestic giant energy giant Xiexin Photovoltaic, raising the production yield by 1 percentage point and saving annual cost by 100 million yuan. The first "China made 1%" power model.

Outside Jiangsu, China's largest tire manufacturer, Sinochem Rubber uses the ET industrial brain to increase the average qualification rate of blends by 3% to 5%.
