There are four basic electronic devices that can be used to measure solar energy: (1) the photoresistor, which is a device whose resistance changes with the ambient light, (2) solar cell whose output power is proportional to the ambient light, (3) photodiodes whose output current is proportional to the light, and (4) thermopiles which convert
Photoresistors are the passive components that use luminous light to change the resistance and generate electric signals accordingly. The value of resistance depends on the amount of light falling on it and is inversely proportional to the amount of light i.e, the more the intensity of light less is the less resistance developed.

When light hits the photoresistors their resistance values decrease, and the increases resistance for less light. By using four photoresistors together, the system can determine where the sun is by comparing values read from the photoresistors. Figure 3.

A photoresistor is a type of light-dependent resistor that varies its resistance values based on the light incident on it. These photoresistors tend to decrease their resistance values with an increase in the intensity of the incident light. Photoresistors exhibit photoconductivity.
These are; the photoresistor, a device whose resistance changes with the ambient light, solar cell whose output power is proportional to the ambient light, photodiodes whose output current is proportional to the light and thermopiles which convert light into temperature into voltage.
Photoresistors come in many types. Inexpensive cadmium sulfide (CdS) cells can be found in many consumer items such as camera light meters, clock radios, alarm devices (as the detector for a light beam), nightlights, outdoor clocks, solar street lamps, and solar road studs, etc.
Photoresistors are not as sensitive to light as photodiodes or phototransistors. Some of the applications of photoresistors are as follows- These are used as light sensors. These are used to measure the intensity of light. Night light and photography light meters use photoresistors.
Photoresistors are included into electrical circuits to exploit their variable resistance. For example, in a voltage divider circuit, the photoresistor is hooked up in series with a hard and fast resistor. The voltage throughout the photoresistor modifications as its resistance varies with mild ranges.
The running principle of a photoresistor, also referred to as a mild-based resistor (LDR) or photocell, is based on its capacity to alternate resistance in reaction to various ranges of light, since it doesn't have the P-N junction diode so they are made of semiconductor material of high resistance.
