How to Wire a Photocell to a Light: A Step-by-Step Guide

Inside a photocell, there is a semiconductor material that has a high resistance in the dark. When light shines on the material, electrons in the semiconductor absorb energy from the light and are able to move more freely, reducing the resistance of the material. This change in resistance is what allows the photocell to detect light levels.

What is a Photocell? Understanding the Basics

Photocells are made of a semiconductor material that absorbs photons of light and generates an electric charge, which affects the conductivity of the material. The basic principle of a photocell is that when light falls on its surface, it causes the electrons in the semiconductor material to move from the valence band to the conduction band ...

Photoelectrochemical oxidation (PECO) is the process by which light enables a semiconductor to promote a catalytic oxidation reaction. While a photoelectrochemical cell typically involves both a semiconductor (electrode) and a metal (counter-electrode), at sufficiently small scales, pure semiconductor particles can behave as microscopic photoelectrochemical cells. PECO has applications in the detoxification of air and water, hydrogen production, and other applications.
