Monocrystalline solar cells that are produced using the relatively inexpensive CZ method (Czochralski method) display a noticeable drop in efficiency of more than 1% in absolute figures under sunlight within a few hours. This effect is called Light Induced Degradation (LID). Solar cells and modules are sold in relation to their performance. This is why elimination of light induced degradation holds tremendous economic potential. As early as 2006, a simple method for the regeneration of solar cells was developed at the University of Konstanz which proved to be very efficient at moderate temperatures and light intensity. This well-known method has now been significantly enhanced and modified: the degradation of the Cz silicon solar cells can now be largely eliminated during the production process. The regeneration process is now carried out at much higher temperatures than before, using hydrogen that had diffused into silicon nitride. This makes the regeneration process a lot more efficient and faster. Ideally, this step follows the co-firing process during the production.

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...

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...
