The most common type of photovoltaic light sensor is the Solar Cell. Solar cells convert light energy directly into DC electrical energy in the form of a voltage or current to a power a resistive load such as a light, battery or motor. Then photovoltaic cells are similar in many ways to a battery because they supply DC power.
These sensors are called photovoltaic cells because of their voltage-generating capacity, but the cells actually convert EM energy into electrical energy. Photovoltaic cells are very important in instrumentation and control applications because they are used both as light detectors and in power sources that convert solar radiation into .
A photoconductor is a device whose resistance (or conductivity) changes in the presence of light. A photovoltaic device produces a current or a voltage at its output in the presence of light. In this Chapter, we discuss photodiodes which are by far the most common type of photovoltaic devices.
The tracking system includes a solar panel, microcontroller, gear motor system, solar panels, and light-dependent resistors (LDR), which were utilized as a sensor. The system also comprises a real-time clock and limit switch, which resets the position of the solar panels at the end of the day.
