Solar Cell vs. LED: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on February 10, 2024
Solar Cell converts sunlight into electricity. LED emits light when electrically charged.

Key Differences

A solar cell, fundamentally, is a device that converts sunlight into electrical energy. It's a cornerstone of solar panels and a crucial component in solar power systems. On the other hand, an LED (Light Emitting Diode) is a semiconductor light source that emits light when current flows through it. While a solar cell harnesses energy from the sun, an LED uses electrical energy to produce light.

The working principle of a solar cell revolves around the photovoltaic effect, where sunlight hitting the cell creates an electric current. This process is key in renewable energy generation. LEDs, conversely, work by electroluminescence, where electric current passes through a microchip, illuminating the tiny light sources to emit visible light. LEDs are known for their efficiency and long lifespan.

In terms of application, solar cells are primarily used for energy generation in residential, commercial, and industrial settings. They play a significant role in reducing reliance on fossil fuels. LEDs find widespread usage in lighting applications, from household bulbs to streetlights, due to their energy efficiency and minimal heat production.
