The photovoltaic industry is recognized as one of the strategic industries, but in recent years, LED overcapacity and the export of photovoltaic products have been blocked, and the entire photovoltaic industry has been challenged. However, judging from the semi-annual reports of some listed companies released one after another recently, the performance of listed companies in the photoelectric industry is not ugly. The performance of some companies such as LED and optical communication has also shown a trend of substantial growth. so has the optoelectronic industry bottomed out and is its performance in the market picking up? With take a look at this reporter from, China Light Fair will field back of reported: Reporter from is held the 15th session, China International Optoelectronic Expo on the know to the photoelectric industry covers various fields such as optical communication, precision optics, photoelectric display, LED lighting, laser infrared, photovoltaic, etc. Photoelectric technology and products have spread all over modern production and life. the industry as a whole has maintained a relatively fast development speed, but in recent years, the photoelectric industry has encountered a bottleneck in development. Wang Yu, dean of the Institute of Optoelectronics of the Chinese Academy of Sciences, said in an interview that from the current development of the optoelectronics industry, everyone is still too eager for quick success, including photovoltaic, LED, in this respect, there are still some technical problems that have not been really solved. Now many of our developments are solved by a large amount of investment in resources, which is easy to cause low benefits. However, from the semi-annual report of the listed company just released, the sales volume of the LED market in the first half of the year increased significantly year-on-year, and the profitability of the company was good. According to the announcement, the five LED companies of Sanan Optoelectronics, Dehao Runda, Guoxing Optoelectronics, qinshang optoelectronics and xuelaite achieved revenue of 16. 7. 4 billion yuan, 13. 5. 3 billion yuan, 5. 4. 6 billion yuan, 4. 6. 2 billion yuan, 1. 9. 2 billion yuan, a year-on-year increase of 22. 13, 10. 52, 22. 93, 26. 78, 8. 73. Correspondingly, the output value of the LED industry in the first half of the year continued to rise, up 25 year-on-year, higher than the growth rate of 23 in the whole year of last year. Industry experts said that the photoelectric industry is expected to bottom out. Mr. Yang Xiancheng, executive vice chairman and secretary general of China International Optoelectronics Expo, said in an interview that in terms of the current direction, it may be at the end of this year or late at the beginning of next year. the industry will begin to recover gradually.
