  • Solar Cell Contacts From Tubes

    Together with industrial partners Merck, Heraeus and ASYS, researchers from the Fraunhofer Institute for Solar Energy Systems ISE have developed innovative new materials and contactless techniques for applying ultrafine, homogeneous contact fingers to solar cells. This ‘dispensing’ technology can be more

  • New organic semiconductor material

    Researchers of the Christian-Albrechts-University of Kiel (CAU), Germany, successfully integrated organic tin into semiconducting polymers (plastics) for the first time. Semiconducting polymers can be used, for example, for the absorption of sun light in solar cells. By incorporating organic tin int more

  • Charge transport jamming in solar cells

    Researchers from the Max Planck Institute for Polymer Research in Mainz, jointly with scientists from Switzerland and Spain, have investigated the working mechanism of a new type of solar cells in which an organic-inorganic perovskite compound forms the light-absorbing layer. These cells can be prod more

  • Improvement of power generation efficiency of solar cells and evaluation by fluorescence spectroscopy

    The light in the high-radiance wavelength region of the solar spectrum is not utilized effectively by silicon crystal-based solar cell modules. "Fluorescent materials" convert the ultraviolet component in the sunlight into light in the longer wavelength region where this solar cell modules can generate power. This article describes an example, how the efficiency of a fluorescent material can be evaluated, using a fluorescence spectrophotometer equipped with an integrating sphere, and a special program, which allows the determination of quantum yields of powders in a very comfortable way. more
