The present invention relates to a photovoltaic tracker using a photodiode. The purpose of the present invention is to provide a photovoltaic tracker which is simply and inexpensively manufactured consisting of a photodiode, a transistor, a resistance and a DC motor, without control by means of a separate program, and which rotates a solar cell part along the direction of the light of the sun being incident to the photodiode. To this end, the present invention comprises: a solar cell part which comprises at least one solar cell, converts the incident light of the sun into electric energy, and is rotated by means of control of a body part; and the body part which is connected to the lower side of the solar cell part and rotates the solar cell part along the direction of the light of the sun being incident to the photodiodes each attached to both ends of the outside. The body part comprises: a power supply part including a printed circuit board (PCB) for supplying power; the photodiodes, each of which is attached to both ends of the outside; a transistor for operating a DC motor according to a signal applied from the photodiode which is in a forward bias status; and a DC motor which is connected to the lower side of the solar cell part and rotates the solar cell part in the direction of incidence of the light of the sun according to the signal applied from the transistor. |
