Patent number: 10340404Abstract: Provided is a multilayer film including inorganic particles having a band gap energy of 3.3 eV or more and inorganic particles having a band gap energy of less than 3.3 eV in different layers. Here, the layer including inorganic particles having band gap energy of 3.3 eV or more is disposed at an upper portion than the layer including inorganic particles having a band gap energy of less than 3.3 eV. Accordingly, the layer including inorganic particles having a band gap energy of 3.3 eV or more is included close to incident light to increase a reflectance in UV region and induce internal reflection, thereby enhancing energy conversion efficiency of a cell. At the same time, the multilayer film may include a lower encapsulant layer or backsheet including inorganic particles having a band gap energy of 3.3 eV or more, thereby increasing reflectances in visible and IR regions and thus reducing a loss of the incident light.Type: GrantFiled: November 8, 2013Date of Patent: July 2, 2019Assignee: LG Chem, Ltd.Inventors: Hyun Cheol Kim, Je Sik Jung, Do Won Ahn
