  1. How Do Photocells Work By Specialized Power Products

  2. A photocell (photoconductive or photovoltaic) is an electrical device that connects and communicates with a transformer. It is a sensor/ resistor that convert light into electricity. When light falls, it transmits energy into the semiconductor part of the cell. Introduction

  3. It is made of two types of semiconductors called “n” and “p. When it is connected to a battery, it conducts a little electric current. What is photocell made up of?

  4. Working of Photocell • The production of electricity in it begins where the two types of semiconductors are joined together. • It is called the p-n junction.When the sun shines on it, its photons get activated. • The said bundle of photons can energize an electron and release it from its covalent bond.

  5. This produces an electron that is free to move and leaves behind a hole in the covalent bond that can accept another electron. • If this freed electron is in the p-n junction region, it will be pulled across the junction into the n-type semiconductor by the small voltage at the junction. • A freed electron in the p-type semiconductor will then fill the hole in the p-n junction that it left behind.

  6. This electron will leave its own hole, which will be filled by another freed electron. • Some of the extra electrons in the n-type semiconductor are attracted to the p-side of this junction.

  7. When the right type of light hits the photocell, electrons on the p-side of the p-n junction receive energy that allows them to move across the junction into the n-type semiconductor. • When these electrons pass through the circuit, they give the energy they have gained to a light bulb or other electric appliance.

  8. Application of a photocell • A common application of it is the light-dependent resistor (LDR), which is used in light sensors, street lights and energy-efficient lighting solutions. • A photocell is also used in efficiently using daylight by turning off lights when natural light reaches a normal level. • They are used for energy saving, convenience, and safety purposes.

  9. Conclusion • A photocell can also used indoors in a space with windows, when there is no natural sunlight coming through a window, the sensor powers on your indoor lighting fixtures. • You can visit SPPE for quality service and best sensor power photocell products.
