Patent number: 8685260Abstract: A known method of forming organic semiconductor devices employs the deposition of a conductive polymer onto a substrate to form electrodes or conductive tracks and then to apply an electrical material such as an organic semiconductor on top of these tracks. Although the conductive polymer serves as a highly efficient injector of electrons into the semiconductor, it is not a good conductor. This introduces undesirable inefficient in the supply of current to and from the semiconductor. Worse still the conductivity may deteriorate with time. A solution to this problem has been found by printing the polymer (7) onto a conductive layer (6) carried on a substrate (5). The printed polymer (7) is then used as a resist during a process in which parts of the conductive polymer not protected by the polymer are removed. The resulting device benefits from the good electron injection qualities of the conductive polymer (7) and efficient conduction by virtue of the underlying conductive layer (6).Type: GrantFiled: April 11, 2007Date of Patent: April 1, 2014Assignee: Novalia Ltd.Inventor: Kate Jessie Stone

Publication number: 20130284245Abstract: A multi-layered film, a backsheet for photovoltaic modules, a method of manufacturing the same, and a photovoltaic module are provided. The multi-layered film can be configured so that a resin layer including a fluorine-based polymer and an oxazoline group-containing polymer is formed on a substrate. As a result, the resin layer including the fluorine-based polymer can have excellent durability and weather resistance, and show high interfacial adhesive strength to the substrate. During the preparation of the multi-layered film, a drying process can also be performed at a relatively low temperature, so that the manufacturing costs can be reduced and the quality of the product can be prevented from being deteriorated by thermal deformation or thermal shock. The multi-layered film may be effectively used as the backsheet in a variety of photovoltaic modules.Type: ApplicationFiled: June 26, 2013Publication date: October 31, 2013Inventors: Hyun Cheol KIM, Yoon Kyung Kwon
