Photovoltaics with full concentration

30.05.2014

New manufacturing concept lowers costs

The development of photovoltaics is far from over. The prices are dropping and their external appearance today ranges from textiles furnished with thin-film cells to large-scale free-standing plants based on silicon. Progress is also being made with the technology.


New multi-junction solar cell with focusing optics

(© AZUR Space)

The BINE-Projektinfo brochure “Energy from a thousand suns” (02/2014) presents modules made of multi-junction solar cells, which are combined with optical concentrator systems and track the sun. This concept focuses the sunlight by up to a thousand times and a solar cell has reached a record efficiency of 44.7% in the laboratory.

With multi-junction solar cells, layers of different semiconductor materials are stacked on top of one another. The current standard is the triple-junction cell that consists of three sub-cells. Each of them can convert a different spectral range of the incident sunlight into electricity. The entire cell reaches its high performance through the interaction of the sub-cells.

Because it is complex and expensive to manufacture multi-junction solar cells, the cells are still combined with focussing optical systems. For this purpose, comparatively cheap mirror systems or Fresnel lenses are deployed. This results in highly efficient modules at competitive prices, which are particularly suitable for regions with a high proportion of direct solar irradiance.

The research project is being conducted by the Fraunhofer Institute for Solar Energy Systems (ISE) together with partners from industry. An industrial production plant for these cells has now commenced operation.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

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...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

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...

Im Focus: Stem cell divisions in the adult brain seen for the first time

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...

Im Focus: Interference as a new method for cooling quantum devices

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...
