Component cost will be as low as $1 W! Golden concord perovskite component development success

Recently, the xin xin group suzhou association of nano science and technology co. , LTD. ( Golden concord nano) Released its in perovskite photovoltaic component technology breakthrough. Golden concord nano has built the first level of 10 mw large perovskite component pilot production line, complete the relevant material synthesis and the development of manufacturing technology, and has begun to 100 mw production line in perovskite commercial production of photovoltaic modules.

perovskite technology has become the world's most high-profile emerging photovoltaic technology, expect perovskite technology in the industry to further improve the photoelectric conversion efficiency at the same time, can reduce the cost of pv components manufacturing.

golden concord nano 10 mw pilot production line made of perovskite photovoltaic modules for 45 cm * 65 cm, the photoelectric conversion efficiency reached 15. 3%. This is the most widespread worldwide perovskite photovoltaic components, is also a large area of perovskite module efficiency highest value. M, is the construction of 100 mw a mass production line components photoelectric conversion efficiency could reach as high as 18% above. Under the condition of existing technology, made in 100 mw production line perovskite photovoltaic components manufacturing costs are expected to be less than 1 RMB/W, mass production, the working life of the components will reach more than 25 years. When the capacity to expand to more than 1 gw, perovskite component manufacturing costs will also be further reduced to 0 per watt. 7 yuan. Such a low cost of components, which means that the cost of pv systems will be lower than 3 yuan /, the cost of photovoltaic power even in eastern China are significantly lower than thermal power.

in parity on the Internet become the industry's most focused on the present work, the significance of this technology is self-evident, can say, on the day of the success of the perovskite is photovoltaic industry to achieve full parity.

after all kinds of photovoltaic cells and component technology, is the complete technology development abroad and then introduce a full set of production equipment in the domestic production,, PERC, HJT ordinary silicon and amorphous silicon, CIGS, CdTe is exactly; And perovskite technology, is the first time that Chinese companies from the materials, equipment to fully realize the product of independent research and development process. The success of the large area of perovskite component production technology development, mark China's photovoltaic industry formally from followers to become the leading technology.

first perovskite materials is a kind of synthetic crystal materials, material formula can constantly adjust, iteration, in the view of improving the performance of material and reduce the manufacturing cost. And the crystalline silicon and no can adjust, can only on the purification process.

second, perovskite materials is not sensitive to impurities, usually about 90% purity of perovskite materials can be used in the manufacture of efficiency reached more than 20% of the solar cell. Crystalline silicon material is sensitive to impurities, purity must reach 99. More than 9999% can be used in the manufacture of solar cells. Nature has brought significant difference of purity requirements of cost difference.

perovskite materials absorption ability is much more than silicon material. The thickness of the silicon wafer in crystalline silicon solar cells are usually 160 to 180 microns, and perovskite titanium calcium deposits in the solar cell thickness is only 0. 3 microns. A composed of 60 pieces of silicon crystal silicon components use silicon materials about 1 kg, and the same size of the perovskite component consumes only 2 grams of perovskite materials.

the perovskite materials can dissolve in ordinary solvents, perovskite components can be through the solution coating process, the entire production process temperature not to exceed 150 degrees. And the crystal silicon ingot casting and lifting will need high temperature above 1500 degrees, the difference of production energy consumption.

advantage based on the above and perovskite technology since 2009, got the attention of the academia and industry rapidly. Almost all related to materials science at home and abroad of universities and research institutions are associated with perovskite photovoltaic technology research, photovoltaic enterprises at home and abroad have also started the perovskite pv modules production technology development. As of February 2019, perovskite laboratory efficiency of solar cells has reached 23. 7%, more than a polysilicon, copper indium gallium selenide, traditional photovoltaic technology such as cadmium telluride laboratory efficiency.

golden concord nanotechnology team leader Dr Fan is introduced: & other; From the development trend of perovskite laboratory efficiency of solar cells will be more than the laboratory efficiency of monocrystalline silicon in three years. In view of gallium arsenide ( 35) The high cost of solar cells ( For the crystalline silicon cells have hundreds of times to thousands of times) , not in daily application promotion, perovskite at the appointed time will become the mainstream of the highest efficiency and lowest cost photovoltaic technology. ”

at the beginning of the perovskite technology available, due to the material design is not yet mature, its stability has been a lot of questions. Since 2016, with the application of new multiple ion mixed perovskite materials, and gradually inorganic buffer layer material, and the working life of the perovskite solar cells will increase steadily, and in the lab can reach 1000 hours continuously work attenuation is less than 5%. Golden concord nano materials for perovskite photovoltaic component development and encapsulation technology, can guarantee the stability of perovskite components more than 25 years of working life.

golden concord nano technology team from xiamen but uh guano can co. , LTD. But the founder of China is a country of one thousand people in xiamen program distinguished expert Dr Fan. Began in 2013, xiamen, but China is engaged in the perovskite photovoltaic component technology development, is the first worldwide in perovskite production technology research of one of the enterprises. At the end of 2016, mergers and acquisitions but China xiamen golden concord group, at the same time, start building 10 mw level in suzhou perovskite component pilot production line at the end of perovskite component pilot production line at the end of the year, pilot production related technology development is complete, start the preparation of 100 mw production line.
