Patent number: 9478678Abstract: A front sheet of solar cell, a method of manufacturing the same and a photovoltaic module are provided. The front sheet of solar cell can effectively block infrared rays (IRs) by forming an IR blocking layer including a cholesteric liquid crystal (CLC) material on a substrate. Thus, an increase in temperature of a cell can be suppressed so that the power generation efficiency of the cell can be improved. Also, the multi-layered sheet can be configured so that a UV blocking layer including a fluorine-based polymer and a wavelength conversion material can be formed on the IR blocking layer. Thus, wavelengths of a UV region can be converted into wavelengths of a VR region so that the power generation efficiency of the cell can be improved, and discoloration and deformation caused by UVs can be prevented so that the weather resistance can be improved.Type: GrantFiled: July 30, 2015Date of Patent: October 25, 2016Assignee: LG CHEM, LTD.Inventors: Hyun Cheol Kim, Moon Soo Park, Dae Hee Lee, Yoon Kyung Kwon, Hyun Seong Ko
