PURPOSE: A light guide concentrating type photovoltaic power generating device is provided to increase the efficiency of a system by guiding light from a peripheral part and directly concentrating incident light on a solar cell. CONSTITUTION: A first optical component(30) is formed on the upper side of a solar cell(20) and deflects incident light. A second optical component(40) is optically combined with the lower side of the first optical component. The second optical component guides light deflected from the first optical component to the solar cell. The second optical component includes a light input unit(44), a plurality of total reflection surfaces(46), and an output surface(48). An auxiliary optical component(50) concentrates light outputted from the second optical component on the solar cell. A center optical component(60) concentrates incident light from the center of the first optical component on the solar cell. |
