PURPOSE: A sensor for tracking the position of the sun, a photovoltaic power generating device including the same, and a method for tracking the position of the sun are provided to improve the generation efficiency of a solar cell module by moving the solar cell module according to the position of the sun. CONSTITUTION: A front sensor(162) is arranged in parallel to a solar panel and senses sunlight. The front sensor has a square shape. A plurality of lateral sensors(163,164) are arranged on the edge of the front sensor and have a hexahedral shape. |
