PURPOSE: A condensing device of a photovoltaic system is provided to extend a lifespan of a solar cell due to high heat and to prevent the surface temperature rise by installing a square cone between the condensing lens and the solar cell and condensing the light through the condensing lens. CONSTITUTION: A collection device of a photovoltaic system includes a condensing lens(10), a solar cell(20), and a cube cone(30). The condensing lens is rectangular. The cube cone is positioned between the condensing lens and the solar cell. The condensing efficiency is improved by the cube cone. The four inner sides of the cube cone are composed of reflectors. When the condensed sunlight is transmitted, the sunlight is sent to the solar cell without loss by the reflector of the cube cone. |
