The main barrier to large-scale deployment of PV systems is the high production cost of electricity, due to the significant capital investment costs. Research is engaged to reduce manufacturing costs and to raise the efficiency of the cells. Today conventional PV cells made of silicon are converting only a fraction of the solar light spectrum around 17%.
FULLSPECTRUM's multi-junction solar cells are able to catch more sun light energy due to their composition of different materials, including gallium, phosphorus, indium and germanium. These multi-junction solar cells are expensive and have only been used for applications in space. However, the cost can be considerably reduced by arranging them in special panels witch include lenses that focus a large amount of solar energy onto the cells. These concentrators can reach far above 1000 times the natural solar power flux and have also been the object of the project research.
FULLSPECTRUM is an integrated project involving 19 European public and industrial research centres from seven EU Member States, as well as Russia and Switzerland. It is coordinated by the Universidad Politécnica de Madrid, Instituto de Energía Solar and started in November 2003 with an overall budget of € 14,7 Million of with the European Commission financed € 8.4 Million.
The European Commission has spent more than € 105 Million in research on photovoltaic energy since the start of Framework Programme 6 in 2002. Many of the projects are trying to get production costs of silicon solar cells down.
Energy research is constituent of the European Union Energy and Climate Package. One of its ambitious targets for 2020 is to increase by up to 20% the level of renewable energy in the EU's overall final energy consumption. To reach this goal the European Commission started the Strategic Energy Technology (SET)-Plan.
The Solar Europe Industrial Initiative as part of the SET-Plan has recently elevated its target for the participation of photovoltaics in the European electricity demand by 2020 from 3% to 12%. This can be translated into installing from 350 up to 400 GW P (Gigawatt of peak capacity) in photovoltaics, corresponding to an average growth of ~40% per year from today's situation.
Back in 2006, the total installed capacity of PV systems in the EU was 3,4 GW P , representing approximately 0,5% of the total EU electrical capacity. The electricity generated by PV was approximately 2,5 TWh (Terawatthour), or 0,1% of the demand. The annual installations of PV systems in 2006 in the EU reached 1250 Megawatt.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
