preamble
the world's photovoltaic industry average annual rate of 31.2% of the rapid development in the world's energy generation first in the market growth rate is expected to more than 2030 photovoltaic power generation will account for 30% of total world electricity generation, photovoltaic power generation by 2050 will become the world's major energy pillar industries. According to the national trend, we have introduced a strong policy or formulating development plans, the PV market is showing a pattern of vigorous development. At present, China has more than 1000 various PV companies, China has become after Japan, the European solar cell producer. In 2008, it can be said that China's photovoltaic materials industry landmark year. Boom spawned by the photovoltaic industry raw materials companies everywhere. A number of new PV companies is expanding its production around the polycrystalline silicon, monocrystalline silicon projects have been started, so that Chinese PV industry has shown a bustling scene.
the development of solar photovoltaic industry, talent is the key to achieving sustainable industrial development. Rapid development and personnel training silicon materials and photovoltaic industry is lagging behind the conflict, resulting in more and more strained silicon material and human resources of photovoltaic production enterprises; basic personnel training curriculum, teaching materials and curriculum quality support important. As a newly opened professional, there is no ready-made supporting materials and reference can learn, according to the editorial group of professional positions require silicon technology, relying on a number of Silicon business, engineering and technical experts to develop business and employ silicon material and write photovoltaic industry series.
This series aims to the main chain of the main line of photovoltaic material, relates to a silicon base material, a silicon material is detected, production of polycrystalline silicon, the preparation of crystalline silicon, wafer processing and testing, photovoltaic materials production equipment, production technology of solar cells, solar modules production technology.
In this series of textbooks written in, enough theoretical knowledge with practical principle, easy to understand, focusing on practical skills of operation.
The book sets the editor over the years in Czochralski silicon technology research and production practice experience, combined with theoretical basis, with plenty of space and site photos elaborated Czochralski silicon production technology the whole process, with a new look dedicated to the readers, in order to achieve the purpose of training practical talents.
This book can be used as teaching vocational majors solar photovoltaic industry silicon technology, at the same time as a corporate job training materials for employees, but also can serve as relevant professional engineering and technical officers to learn.
The book edited by Huang Zhi, Wang Li; who also participated in the preparation of Deng Feng, Yang Qian Mountain, Tangzheng Lin; book by the presiding yellow rose, Deng Yongzhi. Teachers participating in the review made many valuable comments and suggestions, to express my heartfelt thanks.
material development is a gradual process, this series of textbooks is just a start, there are inevitable shortcomings in the preparation process, ask the community criticism, the editorial board will continue to modify future work and perfect. We believe that publishing this series of teaching materials, will promote the further development of silicon materials and PV industry in China.
