2008 worldwide more than 1,000 new large-scale photovoltaic power stations have been established, and the formation of the League of power network. Among them, the construction of many power plants can be divided into many stages of construction, so taking into account the power station is under construction, the total will be higher. Union network in the power station, power station in Spain accounted for about 600, Germany and the United Kingdom occupy more than 120, respectively. It is also worth mentioning that the roof of the Belgian installation of solar power generation equipment and the Czech Republic, open-air installation.
In Asia, South Korea in 2008 with more installation of photovoltaic power generation equipment and the top rate. In Europe, in 2008 the number of photovoltaic power generation equipment installed in more than 800 countries have been on the rise. There are also 1500 power station is under construction. United States, with more than 400 photovoltaic power stations, the world's second-largest in the world.

Luxembourg Institute developed a conversion rate of 12% of the CIGS solar cells
Luxembourg Institute of the University developed a solar cell conversion efficiency of 12% of the CIGS (Cu, In, Ga, Se)-based solar cell modules. The Institute is located in Luxembourg at the University of TDK's industry-university co-operative research projects "TDK Europe Professorship" under the framework in April 2007 established. Mainly engaged in the new solar cell materials and manufacturing process development.
In order to enhance solar cell conversion efficiency of the Institute, developed a thin-film solar cell absorption layers and isolation layers. The future will be located at the Institute in Berlin, Germany, Helmholtz-Zentrum Munchen layer to develop the use of these solar cells.
In addition, the Institute has also successfully developed a non-high In the solar cell. Manufacturing methods can be used in the plating method to reduce costs. Conversion efficiency of 3.2%. According to the Institute of solar cells that use the same kinds of material conversion efficiency of solar cells is the world record of 3.4 percent.

European market for solar cell conversion efficiency requirements
With the demand gradually warmed, the European market for solar cell conversion efficiency is also improved solar battery factory that the recent request of many customers in Europe, poly-silicon solar cell conversion efficiency to be 16-16.2%, and conversion rates in the This will gradually be included under the low-end products.
Solar battery factory that has been the European market demands high quality, the recent conversion efficiency of solar cells required to enhance the trend of 15.8 percent from the previous standard of about 16-16.2% of jumped. Experts believe that lead to the conversion efficiency of solar cells in addition to the main reason for manufacturers to upgrade production quality, the lack of polysilicon than ever, the case of mixing to reduce the net conversion efficiency of polycrystalline silicon may be prompted to upgrade is one of the factors.
In addition, in 2009 a number of manufacturers of solar cells to actively enhance the conversion efficiency of solar cells, including polycrystalline, single crystal solar cells were set to challenge the 17% and 18% of the conversion efficiency goals, is expected to be into the second half will also be in volume production However, because each use different techniques to achieve the conversion efficiency of the threshold, it is estimated that the successful mass production or will produce different results, rather than the majority of enterprises are able to successfully import.
Some manufacturers have indicated, in addition to the conversion efficiency, the increase in the assessment of the cost of production is regarded as one of the most important, if the input a large amount of money, manpower and equipment, only 1 percentage point increase in the conversion efficiency, and can not be effective in the short term cost recovery, and enhance the conversion efficiency does not mean effective.

Sharp mass production of thin film solar cells
Sharp Corp. Recently said that mass production of thin-film solar plant cells, 1 the annual output of about 160,000 KW of electricity. This glass substrate in the silicon membrane to form a new type of solar cells, and is widely used in silicon solar cell compared to only 1% of silicon.
Sharp's thin film solar cells based on a large area of about 1x1.4 meters formed glass substrates. Up to 9% of the energy conversion efficiency of thin film solar cell industry is the most efficient. Sharp to spend ¥ 22,000,000,000 establishment of low-cost thin-film solar cell production line. The company intends to promote solar power plants around the world. Sharp is the world's No. 2 maker of solar cells. Year silicon thin-film solar cells with a capacity of 710,000 KW.

VDMA: photovoltaic equipment in the first quarter sales up 60%
The sales turnover of the manufacturers of equipment, machinery and plants for the photovoltaic industry in Germany for the first quarter of 2009 has exceeded the respective quarter of last year by 60%. The export ratio rose to 89%. The incoming orders significantly increased by 34% compared to the fourth quarter of 2008. This is the result of the current quarterly statistics that VDMA carries out specifically for this industry sector.
For the second quarter the participating companies expect yet another turnover growth of 9%. The orders on hand remain at a high level, the range of orders only slightly went down to 10.2 production months. "The current oversupply of solar modules and financing problems of the manufacturers slow down the expansion of production capacities. Therefore, it comes as no surprise that the sales growth has declined significantly compared to the doubling it has seen for the last three years. Despite the general improvement, incoming orders are still 16% below the first quarter of 2008. However, after the slump in incoming orders in the second half of 2008 this result is respectable, "says Dr. Eric Maiser, director of the photovoltaic equipment forum within VDMA.
The remainder of the year will remain difficult for the entire industry. The participating companies report a significantly higher risk of cancellation or postponement of orders. Moreover, the results show a considerable spread: value chain effects tend to result in slightly better business for machinery and plant manufacturers than for equipment makers. Projects with a longer period of implementation require earlier ordering of equipment. Thus, for incoming orders, it is decisive whether the companies supply fabs for the production of solar modules, solar cells, thin-film photovoltaics or polysilicon . On top of this, another factor is the overall volume of PV business in the individual companies themselves.
The fact is, however, that the long-term potential of photovoltaics is undisputed. The rapid price decline makes photovoltaic products more attractive for an increasing number of clients. Photovoltaic manufacturers currently have to bear a severe pressure on both, costs and innovation. Only those companies who manage to effectively transform latest technology into production will succeed. "This requires new investments even for already existing fabs and will sustain the demand for equipment. Therefore, successful machine makers continue to develop their technology portfolio at high speed. 2009 is a good year for that, "comments Maiser.
