The hottest photovoltaic enterprises expect the go

Photovoltaic enterprises expect the government to support continuous technological reform

not as expected by the industry. At the beginning of 2012, the photovoltaic industry did not bring any comfort

in the last leading quarter, the downstream demand capacity was still insufficient, and major photovoltaic enterprises ended up with embarrassing financial statements. The latest research report released by IMS research, a photovoltaic market research institution, said that in the first quarter of this year, the average market prices of main photovoltaic products such as polysilicon, silicon wafers, cells and modules fell one after another. In the first quarter, the average prices of polysilicon, cells and modules fell by 48%, 57% and 44% year-on-year respectively. Moreover, the collapse of Q-cell, once the largest battery manufacturer, and the reduction of staff and production of first solar and SunPower, and many other negative news kept coming out. For a time, the domestic photovoltaic industry was preparing for a hard time, and the rumors of bankruptcy and shutdown were renewed every day. The bloodbath of the photovoltaic industry seems to be far from over

how to survive the storm is the most concerned issue of photovoltaic enterprises at present. Don't you see the presidents of major photovoltaic enterprises lobbying to get more support from the government; Component companies have set foot in downstream power stations, hoping to sell more boards; In order to save costs, enterprises sharpen their heads to find new technologies, new materials and new processes

for enterprises, how to protect themselves? It is nothing more than the well-known high efficiency and even the low cost of indispensable equipment, but it is even more difficult to realize it. Photovoltaic industry experts once told the author that with the continuous improvement and progress of the process, as the existing leading generation of crystalline silicon cells, its efficiency and cost have almost reached the extreme, especially the front process of photovoltaic panels, has been close to the maximum value of optimization. If you want to make a breakthrough, revolutionary technology is bound to appear

ion implantation technology, passivation technology, selective emitter technology, secondary printing technology, double-layer metal wiring, selective diode and back contact technology have all become the second-generation photovoltaic cell technology concerned by the industry. The author saw the samples of the second generation photovoltaic technology in the applied materials company. The biggest gap with the leading generation products is to move all metal wiring backward to reduce the covering, so as to ensure that the battery panel can receive more sunlight, and at the same time, use the light proof film to reduce surface defects and reduce sunlight reflection. According to Zou Gang, chief technology officer of applied materials, the conversion efficiency of the second generation photovoltaic cells can reach more than 20%, and the recession has also decreased significantly

the so-called second-generation photovoltaic cells do not seem to be far away from us. Xiao Jinsong, general manager of solar energy sales and market development department of applied materials company, told the author that in 2012, Xi'an R & D center of applied materials has demonstrated to more than 50 photovoltaic enterprises on secondary printing, emitter selection and emerging passivation technology. Dr. zhangfengming, the chief technology officer of Tianwei New Energy Holdings Co., Ltd., also said that Tianwei's back-up Design Fair touch technology has made a huge breakthrough and is expected to be commercialized in the near future

the second generation of photovoltaic cells is not a leap forward development, but closer to a gradual revolution. In other words, the second-generation photovoltaic technology can be divided into many "building block" technologies, and different choices of "building blocks" will build different types of second-generation photovoltaic cells. Zou Gang said with a smile, "for every customer, the second-generation photovoltaic cells have many technology combinations, just like a transformer. Every enterprise will have the second-generation photovoltaic cells using different technologies."

technological breakthroughs cannot be separated from the interaction and common progress of the entire industrial chain. The completion and commercialization of the second generation photovoltaic cell technology requires the efforts of the entire industry. With the improvement of yield, the innovation of technology itself, the decline of material cost, and the continuous improvement of process and automation, photovoltaic will gradually change from subsidized energy to one of the main energy sources that can be relied on, which is just around the corner

Shi Zhengrong, chairman of Suntech solar, once told the media that it is also the most used material in FDM printing and molding. The next 10 years will be the 10 years when photovoltaic is facing the transition period. The author believes that in addition to technological innovation and industrial chain optimization, the most important transformation, namely, the reliability and value of photovoltaic power generation, has been recognized and supported by mainstream energy. Transformation is not achieved overnight. Just as the second-generation photovoltaic technology needs to be constantly optimized, upgraded and innovated on the basis of the first generation, the road of photovoltaic power generation also needs the linkage and multiple development of large industries. For example, the improvement of smart electricity will help the better utilization of photovoltaic energy; Photovoltaic will certainly play a great role in helping regions without electricity and with little electricity; With the emission reduction requirements of carbon dioxide, the status of photovoltaic will become more and more important

no one doubts the future of photovoltaic, but whether it can wait for the future is a difficult problem for current photovoltaic enterprises. Zhonghua glass () Department
