Why Use Solar Cells

DESCRIPTION

The Solar Cell. The most common type of solar cells are Photovoltaic Cells (PV cells)Converts sunlight directly into electricityCells are made of a semiconductor material (eg. silicon)Light strikes the PV cell, and a certain portion is absorbedThe light energy (in the form of photons) knocks ele

Why are Solar Cells Important?

Solar cells are small, square-shaped semiconductors made from silicon and other conductive materials. They are manufactured in thin film layers. When sunlight strikes a solar cell, chemical reactions release electrons, generating electric current. Solar is a safe energy alternative. It can replace fossil fuels like coal and gas, which produce air, water and land pollution. Use of solar energy will eliminate the need for conventional fossil fuels. Solar power photovoltaic (PV) panels convert the sunu2019s rays into electricity by exciting electrons in silicon cells using the photons of light from the sun.

Why use solar led lights?

We all were using from the past several years. We never took lighting seriously, though itu2019s a part of our daily lives. But lighting has been changed drastically such as Halogen lights to Fluorescent tubes to Metal Halide Fixtures to CFL lights and now LED Lights. I have made this slide to give an insight on why the solar led lights are the lights of future.
