摘要:
In verschiedenen Ausführungsbeispielen wird ein Verfahren zum Herstellen eines optoelektronischen Bauelements (10) bereitgestellt. Dabei wird eine optoelektronische Schichtenstruktur mit einer ersten Haftschicht (30), die ein erstes metallisches Material aufweist, über einem Träger (12) ausgebildet. Ein Abdeckkörper (36) wird mit einer zweiten Haftschicht (34), die ein zweites metallisches Material aufweist, bereitgestellt. Auf mindestens eine der beiden Haftschichten (30, 34) wird eine erste Legierung (32) aufgebracht, deren Schmelzpunkt so niedrig ist, dass die erste Legierung (32) flüssig ist. Der Abdeckkörper (36) wird so mit der optoelektronischen Schichtenstruktur gekoppelt, dass beide Haftschichten (30, 34) in direktem körperlichen Kontakt mit der flüssigen ersten Legierung (32) sind. Zumindest ein Teil der ersten Legierung (32) reagiert mit den metallischen Materialien der ersten und der zweiten Haftschicht (34) chemisch, wodurch mindestens eine zweite Legierung (33) gebildet wird, deren Schmelzpunkt höher ist als der Schmelzpunkt der ersten Legierung (32), wobei der Schmelzpunkt der zweiten Legierung (32) so hoch ist, dass die zweite Legierung (33) erstarrt und den Abdeckkörper fest mit der optoelektronischen Schichtenstruktur verbindet.
摘要:
Core/shell resonant light absorption and scattering materials and methods incorporated into active layers for increasing the short circuit current and photo conversion efficiency of organic photovoltaic systems are provided. In particular, resonant light absorption and scattering methods and materials for improving the efficiency (short circuit current Qsc) and photo conversion efficiency (PCE)) of organic photovoltaic polymer systems (OPV) that include multilayer nanostructures having a noble metal core and a passivated and functionalized outer shell disposed with the active layer of the OPV in the form of nanospheres and nanorods have been synthesized, characterized and incorporated into the active layers of OPV devices to enhance light absorption through plasmonic light trapping (PLT). In some embodiments the peak extinction wavelength of the nanoparticles is designed to coincide with the wavelength region of the OPV band edge in order to ensure that light trapping is occurring at wavelengths of poor absorption. In other embodiments, a second shell consisting of an optically active material is deposited onto the nanoparticles, the material being selected such that the extinction peak of the core of the nanoparticles is designed to coincide with the emission peak of the rare earth energy transition in order to increase the spontaneous emission rate at that wavelength by taking advantage of the Purcell effect.

摘要:
A barrier film including a substrate, a base (co)polymer layer applied on a major surface of the substrate, an oxide layer applied on the base (co)polymer layer, and a protective (co)polymer layer applied on the oxide layer. The protective (co)polymer layer is formed as the reaction product of a first (meth)acryloyl compound and a (meth)acryl-silane compound derived from a Michael reaction between a second (meth)acryloyl compound and an aminosilane. The first and second (meth)acryloyl compounds may be the same. In some embodiments, a multiplicity of alternating layers of the oxide layer and the protective (co)polymer layer may be used. An oxide layer can be applied over the top protective (co)polymer layer. The barrier films provide, in some embodiments, enhanced resistance to moisture and improved peel strength adhesion of the protective (co)polymer layer(s) to the underlying layers. A process of making, and methods of using the barrier film are also described.
