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.
