Why Solar Energy is Important

Abstract. A compelling argument is made as to why solar energy is important in this first chapter. Fossil fuel resources will last on the order of 100–300 years, yet, burning them generates human-made carbon dioxide (CO2) and is responsible for changes in the Earth, such as global warming and Arctic ice loss.

Photovoltaic effect

The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight. It is this effect that makes solar panels useful, as it is how the cells within the panel convert sunlight to electrical energy. The photovoltaic effect was first discovered in 1839 by Edmond Becquerel.
