The morning of compaq presario 2500 battery September 14, the Beijing Municipal Committee of Science and Technology organized by the Graduate School of Physical Sciences Laboratory of Optoelectronics of the high-performance thin-film thin-film silicon / monocrystalline silicon solar cells and their preparation methods of scientific and technological achievements appraisal. The results of the first people to complete Professor Zhu Meifang made in the identification of the technical study and produce compaq presario 2100 battery a report and test results.
The results of the development of thin-film silicon / monocrystalline silicon thin film solar cells a combination of organic low-temperature preparation and single crystal silicon cells the advantage of highly efficient and stable compaq evo n620c battery, less supplies, technology short-cycle energy consumption and small, high efficiency, good temperature characteristics and stability high, but also to reduce costs and further potential to improve efficiency in achieving efficient and stable solar cells have great advantages. The results of the use of chemical vapor deposition technique in the absence of texture of the CZ single crystal silicon substrates for the preparation of the structure of TiPdAg gate / ITO / n-nc-Si / i-nc-Si / pc-Si / Al solar cell to achieve conversion efficiency of 17.27 percent.
Identification of the Committee spoke compaq evo n610c battery highly of achievements in scientific research. The experts agreed that the results with independent intellectual property rights (patent pending), to achieve a similar battery of international advanced level, improve our country in the thin-film silicon / silicon heterojunction cell research level and international competitiveness, with the industrialization of application prospects. And recommended further strengthening of research, to improve battery efficiency, to increase industry-oriented research and development.
High-tech materials Ministry of Science and Technology Division Director Li Baoshan, a researcher at Beijing Solar Energy Research Institute, Nankai University, Professor Geng Xinhua, Beijing University of Technology compaq evo n600c battery Professor Chen Guanghua, Tsinghua University, Professor Gu Zuyi, Professor Xiong Shaozhen Nankai University, Nankai University, Professor Li Changjian, Semiconductors, Chinese Academy of Sciences Nuo-Fu Chen a researcher at the Institute, Chinese Academy of Sciences, photovoltaic solar systems and wind power generation system, director of quality control center for identification of members and other experts attended the appraisal results compaq evo n600 battery.

Sub-wave length of Germany to develop new methods of conversion

Germany and the United States is located compaq evo n410 battery in Mainz and the Max Planck Institute for Polymer Stuttgart Sony Materials Science Laboratory to develop a new method, using two types of light active material, will be converted into low-energy long-wave photon-photon high-energy short-wave, this method will help develop a new generation of highly efficient solar cells.
Sunlight of a large number of low-energy long-wave photons, the current solar cells can not be effectively converted into high-energy short-wave photons, so that the application of solar cells has been greatly restricted compaq evo n400 battery. High-energy photons are usually only short-wave energy in the laboratory generated laser beam. Max Planck Institute for Polymer Materials Science Lab and Sony experts through a large number of tests, found two new substances, namely, platinum porphyrin ethyl diphenyl anthracene films and to resolve the long-wave low-energy photons in the sun to the high-energy short-wave photons conversion.
The two have been referred to as “photon transfer” of material with different characteristics, including a long-wave-photon absorption as the “receiver elements” and the other as a short-wave photons fired “transmitter elements.” First of all, by the “receiver elements” to receive sunlight in the low-energy molecules compaq evo n410c battery, and then will be able to beam passed to the “transmitter elements”, which in the form of high-energy short-wave photons.
Take advantage of this method can greatly improve the photovoltaic solar cell conversion efficiency. At present, two research institutions have been solved in the green spectrum of sunlight to the gray short-wave long-wave compaq evo n400c battery photon-photon conversion, the researchers will also develop new material group, the realization of solar long-wave spectrum in the other color-photon conversion.

Ministry of Information Industry: Domestic solar cell devices Ultra 500 million yuan

According to the hp pavilion zv5000 battery Ministry of Information Industry news, January-June this year, 10 of China’s solar cell production plant equipment sales have reached 264 million yuan, equivalent to annual sales last year of 80%. Among them, the solar silicon material production and processing equipment sales of 143 million during the first half, solar cells 121 million in sales of manufacturing equipment hp pavilion zd7000 battery. Solar cells is expected this year, equipment sales in China will be more than 500 million yuan.
Since the 20th century, since the 80’s, the world’s photovoltaic industry is the fastest-growing high-tech industries. In recent years, the European Union, the United States, Japan, Australia and other countries have introduced the use of solar power generation to support the policy, vigorously promoted the development of photovoltaic hp pavilion dv9000 battery industry.
At the same time, China’s solar cell devices have been developed rapidly. Since 2003, China’s solar cell equipment to double sales every year is growing hp pavilion dv8000 battery at an average annual growth rate of 97%.
