In September 25th, BASF to create new chemical role of science and Technology Innovation exchange landing in Shanghai, BASF brings cutting-edge technology exhibition and the sustainable development of innovative achievements in the future, including improving energy efficiency, improve the quality of life, through the introduction of more than 20 interactive booth.
In all of its innovation mainly in three fields: resources, environment and climate, quality of life, including food and nutrition, in the energy field, in the face of rapid growth in energy demand, BASF will focus on wind energy, solar energy, electric cars, the organic light emitting diode (OLED), building insulation and concrete technology energy saving the above solutions.
The field of solar energy in photovoltaic cells, BASF launched a new laser transfer printing technology (LTP) and custom type silver / aluminum inks, its goal is not the traditional silver paste but for the whole of metallization process improvement, according to reports, under the action of laser, silver electrode need not and wafer contact, thereby reducing wafer the fragment rate of metal structure, the more narrow, the production of solar cells and thinner, and can improve the yield and production rate of silicon wafer.
This technique is also called the novel non-contact printing technology, BASF and anrentum innovation-stechnologien GmBH as well as equipment manufacturer Schmid GmbH cooperative R & D. It is reported, this new type of printing machine and the Cypo Sol RL customization can replace the existing ink screen printing process, compared with the silk screen printing, the main advantage of LTP, laser technology produces pressure on the thin solar cell wafer not, Schmid R & D center test display, without contacting the LTP process can be broken the highest solar cell wafer rate reduced by 80%.
In the cost aspect, the investment in fixed assets can be relatively reduced (reduce dryer, tail gas treatment is simple), can save silicon materials, equipment for longer periods of time, without the need to replace the screen, the potential to reduce manufacturing cost about 0.60-1.00 cents per watt. Series of products including Cypo Sol RL61-10 cathode silver ink (AQ) / lead), Cypo Sol RL65-10 back electrode aluminium ink (lead-free) etc..
In addition to the new Cypo Sol RL series, BASF provides improved slurry as the traditional printing, such as the Cypo Sol RS51-105 positive silver paste (Wu Qian), Cypo Sol RS51-305 Cypo Sol RS59-102 front silver paste, silver paste (Wu Qian) and so on the back.
In addition, BASF is also developing organic solar cells, the development of new NIR dyes for solar energy application design, can absorb more light, the laboratory conversion efficiency up to 12%, compared to other thin film batteries, BASF technicians think more promising organic solar cell.
The BASF executive board, vice chairman of thin Renmu music said: "innovation of science and technology in the Asia Pacific region to exchange tour kicked off in Shanghai, we are very excited, this underscores our investment in advanced technology and innovation, to realize the sustainable development in our global third big market Chinese commitment." It is understood, the innovation of science and technology department at the beginning of this year BASF headquarters in Germany launched debut, has so far been parade America, Canada, Brazil, ShangHai Railway Station will end in 2013 landed in Mumbai, Brussels, Tokyo and Seoul.
