Honeywell announced the launch of new materials to improve the efficiency of crystalline silicon photovoltaic cells. Valencia, Spain, September 6, 2010 News Honeywell (NYSE: HON) today announced the launch of a series of new electronic materials. Using these materials, crystalline silicon photovoltaic cell manufacturers can improve the power output of the battery by using advanced and efficient battery design

these new materials include dielectrics and dopants commonly used in large-scale semiconductor manufacturing. Honeywell's electronic materials department has supplied electronic materials to the semiconductor industry for more than 40 years, and is now applying its expertise in this field to the photovoltaic industry

Dmitry shashkov, the business director of Honeywell's electronic materials department, said: Honeywell, in the spirit of continuous innovation, continues to apply mature semiconductor technology and materials to the photovoltaic industry. Honeywell's new dopants and dielectric materials help crystalline silicon photovoltaic cell manufacturers apply low-cost and high-yield industrial manufacturing processes to the new solar cell design that has been verified by the R & D laboratory during the "1015" period

solar cell efficiency is crucial for photovoltaic manufacturers. Efficiency improvement means that the same size of the panel will provide higher power output under the same amount of solar radiation. Therefore, Jinan Shijin people all take "providing excellent and cutting-edge experimental equipment for the society" as their main purpose. Battery efficiency is the key determinant of solar energy cost. Specifically, with these new dopants and dielectric materials, manufacturers can apply new technologies in the manufacturing of photovoltaic cells, which greatly reduces the cost of producing electricity per watt compared with the current process

dopants are formulated chemicals that can change the electrical properties of silicon materials, and can selectively change the electrical properties of specific parts of solar cells. Dielectrics are formulated chemicals that can be used as insulators to prevent current from passing through certain areas of PV cells. These dielectric materials also have other advantages. For example, they can be used as a passivation layer to prevent harmful recombination effects, or as a diffusion barrier layer to prevent the diffusion of dopants to some unnecessary areas, and can also be used as mask materials

since impurities will reduce the quality of photovoltaic cells, Honeywell reduces the thickness and saves materials. When designing these new materials, the content of impurities is controlled at a very low level. Crystalline silicon cell structures that can use Honeywell's new materials include selective emitters, back passivation, point contact, and boron back field (BSF) cells. In addition, Honeywell's dopant will make the n-type silicon substrate have the advantages of high specific strength and large specific elastic modulus at the same time, and will be widely used to replace the currently dominant p-type silicon, so as to eliminate the adverse effects caused by the photodegradation effect of p-type silicon. There are many economical and high-yield methods to apply these new materials to silicon wafers, such as silk printing and inkjet printing, as well as other mature methods already used in photovoltaic and electronic manufacturing industries

the development of these new photovoltaic manufacturing materials is completed by Honeywell's advanced R & D institutions in Sunnyvale, California and Shanghai, China. In addition, Honeywell works closely with research institutes, original equipment manufacturers (OEMs) and global photovoltaic cell manufacturers to ensure that these materials are compatible with equipment that has been commercially produced on a large scale and meet the process integration requirements of the entire photovoltaic process

in addition to these new materials, Honeywell electronic materials department also launched solarc antireflection coating for photovoltaic panel products last year, which improves the transmittance of photovoltaic panel glass, thereby improving the efficiency and power output of photovoltaic modules

Honeywell announced this news at the 25th European Photovoltaic Solar exhibition, which is the world's largest photovoltaic solar conference, bringing together global leaders in the solar industry to discuss the scientific and technological issues facing the industry
