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.

In best circles: First integrated circuit from self-assembled polymer
19.02.2018 | Max-Planck-Institut für Polymerforschung
For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale
Researchers from the Institute of Organic Chemistry and Biochemistry of the CAS (IOCB Prague), Institute of Physics of the CAS (IP CAS) and Palacký University...
For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
