On March 10th, the first perovskite photovoltaic standard thematic group in China was established. After the establishment of this working group, it will further accelerate the combing and improvement of the perovskite solar cell standard system, and then formulate and revise the related standards quickly, orderly and scientifically to provide solid standard support for the development of China's perovskite solar cell industry. As the third-generation PV cell technology, perovskite solar cells (PSCs) have more theoretical advantages over crystalline silicon and thin-film solar cells due to their unique properties, including higher efficiency, lower cost, wider range of applications, and so on. At present, China is breaking through the stability, large-scale production, and other problems of perovskite solar cells. And the industrialization for single-junction PSCs is constantly accelerating. Enterprises such as GCL Optoelectronics, Xianna Optoelectronics, and Polar Optoelectronics have completed the construction of 100 MW pilot production line, and plan to start GW production line to expand production capacity. With the gradual launch of large-scale production line bidding, equipment manufacturers are expected to benefit first.
