Solar Cell vs. LED: Know the Difference
By Shumaila Saeed || Published on February 18, 2024
Solar cells convert sunlight into electricity, whereas LEDs use electricity to produce light.
Key Differences
Solar cells and LEDs operate on fundamentally different principles. A solar cell is a device that converts sunlight into electrical energy through the photovoltaic effect. Conversely, an LED (Light Emitting Diode) uses electrical energy to produce light through electroluminescence.
