PROBLEM TO BE SOLVED: To provide a solar cell device which can track the sun precisely by a simple constitution and has high power generation efficiency. SOLUTION: A solar cell 12 is arranged in an area near a focus of a power generating converging lens 10 of a plane shape, constituted of resin and they can be rotated and moved as one piece. The power generating converging lens 10 is fixed to a shaft 20 of a motor 18 for rotational drive. A position of the sun is detected by a position detection sensor 42 by sunlight, converged by a columnar position detection converging lens 40 and a position of the sun is input to a control part 48 as an angle signal. A control signal is sent to the motor 18 for rotational drive from the control part 48 based on a position of the sun, the power generating converging lens 10 and the solar cell 12 are rotated and moved according to a position of the sun and the power generating converging lens 10 is always turned at right angles to sun light. |
