<title> With amorphous silicon thin-film battery as the representative of the thin-film solar cell (hereinafter referred to as thin-film batteries) technology to low-energy, zero-emission, energy payback period is short, no raw material bottlenecks, low cost, easy-to-industrialization, low-light is good, resistant advantages of high-temperature, etc., is considered the most likely to achieve cost of electricity tariffs closer to Internet technology, and thus have more and more vendor attention.
Market share will increase the
From the development rate, in the future market, the proportion of thin-film solar cells will continue to increase. According to iSuppli predicts that by 2013 the global solar cell market, the share of thin-film solar cells from 2008 to 14% to 31%, a huge space for development.
Recently, amorphous silicon solar cell module by the battery manufacturers in China many of the sought after, there are many places have also launched plans for the industrialization of thin-film batteries and has started production. Such as the Han Dynasty can be invested 28.0 billion Holding Group announced to start thin-film solar cell research and development of Heyuan in Guangdong manufacturing base, Jiangsu Arts Co., Ltd.'s first thin-film photovoltaic solar cell production line officially put into operation, Chengdu Apollo Solar Energy Co., Ltd. 5-megawatt photovoltaic cadmium telluride thin-film solar cell production line put into operation and so on.
In view of this situation, Beijing North Finder innovative vacuum technology limited liability company chief engineer office director Chen Wang Shu said that with the thin-film solar cell conversion efficiency, as well as large-scale SONY VAIO TX36TP Laptop Battery cost advantage continues to expand its market share will further increase.
BIPV has a
Industry said that in the BIPV (building integrated photovoltaic) market, direct plating of amorphous silicon on glass thin-film photovoltaic cells, both from a cost and functionality (including visual) point of view, are better than crystalline silicon products . Baoding Tianwei thin-film PV Co., Ltd. Yaohua Mai, chief technology officer, told reporters thin-film batteries than conventional crystalline silicon cells is more suitable for use in building-integrated photovoltaic, especially on the application of component-based approach, so the support of the state BIPV to a large extent contributed to the development of thin-film batteries.
BIPV through the building, mainly the roof and walls together with the integration of photovoltaic power generation, so that their use of green building, environmentally-friendly solar energy resources produce electricity. Chen Wang-shu, said thin-film solar cells use less than a micron or a few microns thick semiconductor material, thickness thinner than the crystalline silicon cells more than 100 times. The semiconductor thin layer can be attached to inexpensive substrates (also called the substrate), such as glass, plastic or stainless steel sheet activity. BIPV applications, which combined with the construction of photovoltaic power generation, solar energy is the direct application of the template as a building materials to the building design, to provide electricity for the building. This approach is often also play a role in energy conservation. Speaking from an aesthetic point of view, thin-film batteries better suited than the crystalline silicon cells, because the template can be made semi-transparent thin-film photovoltaic (partial transparency), and amorphous silicon photovoltaic panels seem to be much more uniform nature. In addition, the amorphous silicon photovoltaic products in the case of weak luminosity is still running well, not very bright in the morning and evening when the sky may still effective power generation, which is the practical application of amorphous silicon cells in a very favorable characteristics.
Currently, BIPV in our country are more and more attention. Industry analysts say, China is a major energy-consuming country, building energy consumption, accounting for 25% of total energy consumption of society, of which construction heating, air conditioning, lighting accounts for 14%, building construction energy consumption 11%, in the future this ratio may also raise. Therefore, solar energy and architecture to organically combine, in the place of the original architectural elements while meeting some of photovoltaic power generation, taking into account the style and architectural appearance of harmony and unity, different from the previous simple and pure photovoltaic projects, particularly suitable for promote the FUJITSU FPCBP95AP Laptop Battery of large cities. Recently, by Zhejiang Chint Solar Energy Technology Co., Ltd. produced 610 square meters DOUBLE GLAZING translucent silicon components of an integrated photovoltaic curtain wall, becoming the first photoelectric curtain wall Hangzhou.
Equipment at home and promote development
Mak Yiu Wah said that as the thin-film battery devices are more expensive than the initial investment of crystalline silicon cells high, and the industry chain is shorter, and therefore to some extent limits the number of smaller investors to enter the capital.
It is understood that, 25MW amorphous silicon thin-film battery production line, sold at 300 million yuan between ~ 400 million yuan, while the 25MW crystalline silicon solar cell production line equipment costs only 40 million yuan ~ 50 million yuan. Therefore, the device will be thin-film solar cells made of the rapid development of the industry play a positive role in promoting.
If the current large-scale use of foreign equipment, production costs will certainly be high, and difficult to reduce. Therefore, the development of thin-film equipment and to meet customer needs, is the domestic equipment manufacturers should solve the problem. Chen Wang Shu said that the international community in recent years many countries in the thin-film solar cell production equipment and process technology research and development invested a lot of money. At the same time, foreign manufacturers blockade of advanced technologies, does not provide equipment and process technology. Thus, leading to many domestic customers fall into the import of equipment "Procurement - backward - and then purchase - and then backward" vicious circle. In his view, from the future national strategic security point of view, the need to strengthen scientific and technological innovation. At the same time, given the amorphous silicon thin-film solar cells made complete sets of production equipment imported equipment cost-effective than the fact that, should seek to support domestic equipment to enter the market quickly, while the production equipment, machine should be in place to restrict the import policy, abolition of import tax rebate policy machine, in order to support national FUJITSU FPCBP80 Laptop Battery.
