  • Patent number: 9279038
    Abstract: Method for producing a cross-linked elastomer in which a mixture is produced comprising at least one latex and at least one starter component for initiating the cross-linking reaction or a latex that bears at least one starter component or starter group, in particular in liquid phase. A photoinitiator is used as a starter component, which photoinitiator, through irradiation with electromagnetic radiation in the ultraviolet (UV light) and/or visible spectral range forms a reactive species. The latex mixture is irradiated with UV light and/or visible light.

  • Publication number: 20090235978
    Abstract: A method for producing photoactive layers, and components, such as solar cells, including the layers. According to the invention, the photoactive layers are produced by forming a non-semiconducting layer from precursor material including at least one metal compound and a salt-like and/or organic reactant on a substrate by printing or blade coating, the layer being exposed to temperatures of less than 300° C., wherein a semiconducting, photoactive layer is formed from the non-semiconducting layer by thermal conversion of the precursor material.
