Nano silver ink "printing" solar cells

Printing pictures and printing documents are commonplace in everyday life, but have you ever seen "printing" solar cells? The Suzhou Industrial Park Enterprise Leader Technology Nanotechnology Co., Ltd. has succeeded in realizing the application of inkjet printing technology in the field of photovoltaic cell manufacturing through technological breakthroughs, using magical nanosilver ink to break through the two major bottlenecks that hinder the development of the photovoltaic industry, and drastically increased conversions. Efficiency also significantly reduces material costs. It is not hard to imagine that printing solar cells in the future is as simple as printing newspapers with ink.

Suzhou Li Dewei Wei Nano Technology Co., Ltd. is a Sino-Italian joint venture company, relying on Hunan Lide Electronic Slurry Company's years of industry accumulation and Israel's internationally leading nano-metal materials technology, and firmly grasping the opportunities for rapid development of printed electronics industry. He is engaged in the research and development, production and sales of ink-jet printing nano-silver, copper inks and related materials. It can be widely used in solar cells, touch screens, and RFID smart labels. Although it is a young technology company, Li Defei Wei has full confidence in his technical strength. Yang Huarong, CEO of the company, frankly stated that the technical threshold for ink-jet printing of nano-metal inks is quite high, and it is even more difficult to mass-produce them. Li Depuwei has succeeded in industrialization.

At present, the development of the photovoltaic industry in the world depends on government subsidies and policy support. However, the healthy development of photovoltaics lies in improving the photoelectric conversion efficiency and reducing production costs. Nano-metal ink jet printing technology precisely solves these two problems. “Using our technology, the photoelectric conversion efficiency of solar cells can be increased by more than 0.6%. We must know that the 0.1% increase is a technological revolution!” Yang Huarong sighed. Compared with existing processes, inkjet printing has dozens or even hundreds of independent nozzles, not only fast, high precision, but also reduce waste, silver consumption can be reduced by about 30%, while reducing the consumption of silicon . According to calculations, compared with the existing process, the solar cells produced by ink-jet printing can increase the benefit of at least 0.6 yuan to 0.8 yuan per tablet, which is in line with the development direction of high efficiency and low cost of the photovoltaic industry.

In the future, Li Dewei Wei will also develop ink-jet printing nano-copper inks, using the original core technology to overcome the problem of easy oxidation of copper inks. The copper conductivity is similar to that of silver, but its price is only one percent of that of silver. This technology has achieved preliminary commercial application and is expected to gradually replace the expensive silver in the future to promote the overall application cost of the photovoltaic industry and electronic information industry. The sharp reduction.
