APPLICATION OF SOLAR CELL IN LIFE

Solar Cell is a device that converts solar energy directly into electrical energy based on photovoltaic

effect. Russell Ohl is considered to be the creator Solar Cell first in 1946. The solar cells are made of thin

layers of material, usually silicon. Electricity generated from solar cells are called solar Power. To create

more energy, people connect more elements together solar cells into generate solar panels. Now, the

solar cell is used in many parts of the world to operate the equipment, providing light and power to

divert support information. Solar panels provide power for equipment in space ships and satellites. Solar

cells supply power needed to operate many kinds of consumer products such as calculators and

watches. Solar systems used to heat water or other fluids to work, or to make steam.

Advantages of Solar Cell are Solar energy makes use of a renewable natural resource that is readily

available. Solar power used by itself creates no carbon dioxide or other toxic emissions. Use of solar

thermal power to heat water or generate electricity will help reduce the Territory's complete

dependence on fossil fuels.

Disadvantages of Solar Cell are Solar thermal systems are not cost-effective in areas that have long

periods of cloudy weather or short daylight hours. The arrays of collecting devices for large systems

cover extensive land areas. Solar thermal systems only work with sunshine and do not operate at night

or in inclement weather.
