PURPOSE: A module for sunlight power generation which includes a graphite sheet is provided to include a sunlight reflection layer which reflects light passing a solar cell again to the solar cell, thereby improving the power generation efficiency of a solar cell. CONSTITUTION: An upper part buffer member(20) is arranged in the lower surface of a transparent substrate. A solar cell(30) is arranged in the bottom surface of the upper part buffer member. A lower part buffer member(40) is arranged in the bottom surface of the solar cell. A graphite sheet(50) is arranged in the bottom surface of the lower part buffer member. A coating layer(60) is arranged in one or both surfaces of the graphite sheet and improves the durability of the graphite sheet.
