Photovoltaic cells, also known as solar cells, convert sunlight directly into electricity through the photovoltaic effect, making them a crucial technology for sustainable energy generation. They are composed of semiconductor materials, typically silicon, which absorb photons and release electrons, creating an electric current.

sunlight directly into electricity

The photovoltaic effect is the generation of voltage and electric current in a material upon exposure to light, forming the fundamental principle behind solar cells. This process involves the absorption of photons, which excites electrons, creating electron-hole pairs that are separated by an internal electric field to produce electricity.

sustainable solution

Fossil fuels are like old, buried treasures that we dig up to make cars go and lights turn on, but using them too much makes the Earth sick because they create dirty air. We need to find new ways to power things that are cleaner and won't run out, like using the sun and wind.

dependence on fossil fuels

Environmental impact refers to the effect that human activities and natural events have on the environment, encompassing changes to ecosystems, biodiversity, and natural resources. Understanding and mitigating these impacts is crucial for sustainable development and the preservation of ecological balance.
