How to generate electricity?
Thin-film low-power glass is plated on ordinary glass of cadmium telluride photoelectric material, so that ordinary glass from the insulator into a conductive conductor, and then become a building material can generate electricity, the power generation layer of each glass after laser engraved Erosion, the formation of 214 small batteries in series, that is, visible on the black glass white lines. Two glass one, through the back of the junction box to collect electricity, can generate electricity, into the inverter can be used directly.
Conveyor belt running at a constant speed, 'robot' automatic operation, 55 seconds, will be off a 1.6 m long, 1.2 m wide cadmium telluride power generation glass.
This is the site of Chengdu Building Materials Optoelectronic Materials Co., Ltd. production line, but also China's first 100 MW of cadmium telluride power generation glass production line, in accordance with the German industry standard 4.0 build, more than 90% of equipment purchased from Germany and other European and American countries, to achieve laboratory conversion efficiency 17.8%, the conversion efficiency of small components 14.5%, reaching the leading domestic level.
The breakthrough of this technology indicates that CNBM has mastered the world's leading independent core technology of large-area cadmium telluride power generation glass and also broke the monopoly of foreign giants. Soon, Chengdu CNBM will take the 'China's high-speed rail' model and introduce , Digest, transform, improve (domestic), go abroad.
Light can generate weak light performance, suitable for Sichuan
In the exhibition hall of Chengdu Zhongguang Optoelectronic Materials Co., Ltd., a black glass with a screen size of a TV screen is covered with curtains, and the glass bulbs are lit up one by one, which is the largest single in the world Body area of cadmium telluride power generation glass. Compared to the smaller area of foreign power generation glass, Chengdu made in the production cost and installation costs are greatly reduced.
Why is the production of power glass? Why was born in Sichuan? In a row of 'discolored' glass before, Chengdu Building Materials Photoelectric Material Co., Ltd. party secretary Yin Xin Jian told reporters that the glass from colorless into yellow and then into black process Is the process of installing the battery power generation, and the formation of the battery is because of the power generation layer coated. 'Thin-film low-power glass products are plated on normal glass cadmium telluride photoelectric materials, so ordinary glass from the insulator into a conductive Of the conductor, and then become a building material can generate electricity, to achieve an organic combination of glass and materials. "Yinxin Jian explained that the power generation layer of each power generation glass after laser etching, the formation of 214 small batteries in series, that is Black glass visible white lines. Two glass one, through the back of the junction box to collect electricity, can generate electricity, into the inverter can be used directly.
'The source of power generation materials is Phyllite bismuth mine, we have the world's only independent mineralization of telluride bismuth ore.' Yin Xinjian said that in the same light, the role of power generation glass to absorb light than ordinary power generation materials Higher than about 10%, even in low light conditions can also be generated by photoelectric conversion of electricity, especially for the light conditions in Sichuan 'rich mineral resources and poor light resources, we are looking for a breakthrough in the adversity of the two major factors.
Let the thickness of one percent of the cadmium telluride crystals, continuous glass 'growth'
Chengdu Building Materials Photoelectric Material Co., Ltd. related to the person in charge, 'Chengdu made' power generation glass has been in the forefront of the world, a piece of 1.6 meters long and 1.2 meters wide power generation glass, its photoelectric conversion efficiency of up to 17.8%, can generate electricity 260 ~ 270 degrees. Even in the case of very weak light, but also through the photoelectric conversion of electricity. A piece of 1.92 square meters of glass, a year can generate 260 ~ 270 degrees, the theoretical calculations, 34,000 glass produced electricity, Equivalent to a normal oilfield a year oil can be converted into electricity.
According to reports, previously, the world's largest monolithic cadmium telluride thin film power generation glass is 0.72 square meters, has not been able to achieve a breakthrough.We should 4 microns thick, equivalent to one percent hair thickness of cadmium telluride thin film uniform , Uninterrupted plating on the glass, the difficulty is very large.
Chengdu Building Materials Photoelectric Materials Co., Ltd. Chengdu new plant area of 30,000 square meters, the total production line of 560 meters, daily production requires only more than 50 workers, the automation rate is very high, 'the operating system in English and Chinese bilingual in the future we can do equipment exports. The core process used in the mill's production line is gas-coating: the glass moves into a vacuum chamber at a high speed in a high-temperature environment, allowing a 4-μm-thick CdTe crystal to "grow" continuously on the glass. It is also a green Recyclable power generation of multi-functional building materials, can replace bricks, curtain walls and other building materials, large-scale integration of photovoltaic construction has laid a solid foundation.
It is estimated that the power plant installed on three sides of the glass can generate more than 200 million degrees a year
As the product continues to go down the line, the company is using power generation glass "armed" plant .Reporters on the scene saw many of the company's plant has been fitted with black glass, from the outside, and ordinary glass curtain wall only color difference, but Behind the wire pull out of the box, but can supply power for the plant.According to estimates, once installed on the power plant glass 3, a year can generate more than 200 million degrees, which means half of the production line power consumption can achieve self-sufficiency. Even the battery car, electric vehicle charging pile power can come from 'power generation glass', the use of 'power generation glass' new energy vehicle charging pile and other applications everywhere.
Compared with ordinary power generation materials, the 'power generation glass' is more durable and has a design life of 30 years. Through power generation, the cost can be recovered in the first 6 years. This opens the imagination for the grid-connected photovoltaic power generation and even for poverty reduction .
'China's existing buildings 40 billion square meters, if the use of' power generation glass '10% transformation, it is equivalent to the construction of the Three Gorges Power Station, and solve the traditional glass curtain wall light pollution problems. "The official believes that with the order' blowout They are approaching their dreams infinitely.
Embracing the dream of building China's First Solar, China Building Materials Group's cadmium telluride thin film solar cell team is devoted to the research, development and industrialization of cadmium telluride thin film solar power glass. Glass, cadmium telluride material, coating technology and equipment of the whole industry chain of Chinese enterprises.
