3 microns, this is the thickness of the film layer of cadmium telluride power generation glass; 0.03 mm, this is the thickness of BOE's flexible AMOLED display; 600 km/h, this is the design speed of the world's first high-temperature superconducting high-speed magnetic levitation engineering prototype...
In the past decade, a large number of original innovative achievements have emerged. On the road of technological research towards the world's scientific and technological frontiers, Chengdu's pace has always been strong.

Build a large mountain restoration power station in Chicheng County, Zhangjiakou, and arrange " Bingdundun " and "Snow Rongrong" green low-carbon road signs in the core area of the Winter Olympics Village and the National Ski Jumping Center... Looking back at the beginning of 2022, the cadmium telluride power glass developed by Chengdu China Building Materials Optoelectronic Materials Co., Ltd. shines on the Beijing Winter Olympics , allowing "Made in Chengdu" to shine in Winter Olympics .
This is the 12th year that , general manager of Chengdu China Building Materials , has taken root in Chengdu to develop cadmium telluride power glass.
power generation glass is power generation glass with the help of new semiconductor materials such as cadmium telluride, allowing ordinary glass to "generate electricity by itself", and realizes that there is light and electricity. When Pan Jingong returned from overseas to become a "Rongdiao" in 2010, the research and development and industrialization of large-area cadmium telluride power glass was still blank at home and abroad.
behind this, a series of problems such as semiconductor material doping and membrane surface crystal growth are needed. "The secret is in the film on the surface of the glass. The total thickness of the film is only 3 microns, which is equivalent to one-twentieth of the diameter of the hair. It is very technically difficult," Pan Jingong revealed.
Faced with the patent obstacles of foreign companies, Pan Jingong and his team resolutely took the path of independent innovation. A full 8 years! After thousands of failures and improvements, it finally broke the international monopoly. In 2017, the world's first large-area (1.92 square meters) cadmium telluride power glass was launched in the production plant of Shuangliu.
Nowadays, the conversion efficiency of cadmium telluride power glass of Chengdu Zhongbian Building Materials has reached the international advanced level, , and Pan Jingong is still leading the team to accelerate forward, pursuing higher goals on the road of cutting-edge research...

From nothing to something, from 0 to 1... Over the past decade, Chengdu's science and technology investment has steadily increased. In 2021, the intensity of the investment in R&D in the whole society is 3.17%, an increase of 1.08 percentage points from 2012. In the field of cutting-edge technology research, a number of key core technologies have been continuously making breakthroughs -
In 2012, Chengdu Dio Pharmaceutical Group's innovative drug - Dio Xinxuekang Capsule was approved to be registered and launched in the EU . marks that my country's therapeutic drugs with independent intellectual property rights have entered the mainstream market of developed countries and achieved a zero breakthrough.
2017, my country's first 6th generation flexible AMOLED production line built by BOE was mass-produced in Chengdu. filled the gap in my country in this industry;
In 2020, Chengdu Qikang Technology launched the first domestic nanopore gene sequencer independently developed, successfully breaking the gene sequencing equipment , high barriers and overseas monopoly in the field of supporting chips and reagent research and development, overcomes the technical difficulties of "bottleneck" in domestic gene sequencing;
In 2021, the world's first high-temperature superconducting high-speed maglev engineering prototype and test line was opened in Chengdu, with a designed speed of more than 600 kilometers per hour. marks a breakthrough from scratch in my country's high-temperature superconducting high-speed maglev engineering research.
Focus on the future industry and seize the initiative in development. Chengdu also performed "outstanding" -In the field of quantum research, the U Electronic Science and Technology team has developed a new declared single-photon source with world-leading level; in the field of xenogeneic organ transplantation , Chengdu Zhongke Og cultivated Humanized genetic pigs are actively carrying out preclinical verification; in the future travel field, Wofei Changkong and other forces accelerate the layout of flying cars, and unmanned taxi has been put into manned demonstration operation...
There is also a set of data worth paying attention to - Over the past decade, Chengdu has received more than 2,200 html science and technology awards from , ranking among the top sub-provincial cities in the country.
continues to explore, and a large number of innovative achievements have emerged, allowing Chengdu's scientific and technological innovation to achieve a leap from quantity to quality and a breakthrough from point to surface. Chengdu's innovation is bursting with surging power.
