A photoelectrochemical cell is a type of device that allows us to use the power of light to generate electricity. It is made up of two main parts, a solar cell and an electrolyte. The solar cell is like a mini solar panel, it takes in the energy from the sun and converts it into electricity. The electrolyte is a liquid that helps move the electrical charge around in the cell. When the solar cell takes in light, it causes the electrolyte to release electrons which travel through the cell and make an electrical circuit. This electrical circuit creates a current that can be used to power our devices!
