A Study on the Present Environmental Scenario due to Pollution by Conventional Energy Sources—and Remedies: Solar Cell with Nanotechnology

Abstract

At present, pollution is a matter of grave concern; it is occur-
ring due to the abundant burning of fossil fuels. Among the reasons
for environmental pollution, one is the conventional method of power
generation to produce electricity. If a portrait of the world’s pollution is
taken, the countries that use non-conventional power make many times
less pollution than those with conventional power usage. As a result of
massive pollution, climates all over the world have been changed, and
people are facing lots of problems. To remedy this vital concern, the
one and only way is to adopt the habit of utilizing renewable energy
sources. Among all renewable energy sources, solar energy is the only
major, environmentally independent source of energy that is sustainable
and can produce a good amount of energy. The basic problem of solar
cell is its high cost and poor efficiency. But new technology (nanotech-
nology) has been discovered that will reduce the cost of solar cell, with
improved efficiency
