General Information
In 1839, Edmond Becquerel discovered
the photovoltaic effect when he
working with a ce
ll made of metal
electrodes
in a conducting fluid,
When the cell was exposed to light,
he realised that it produced more
electricity.
General Information
The Sun provides energy in the form of
solar radiation, or kno
wn as solar energy.
Solar energy is a renewable resource,
and its conversion and usage
as a substitute for fossil fuels
is becoming more popular.
General Information
Solar energy is us
ed to heat water
for domestic use, to heat buildings,
and to generate electricity.
Solar Radiation Definition
Solar radiation is the electromagnetic
radiation emitted by the sun,
often known as the
solar resource or
sunlight.
It may be absorbed and converted into
useful forms of energy such as
heat and electricity

Properties
An important property of PV semiconductors
is the bandgap
It indicates what wavele
ngths of light the material
thus absorb and convert to electrical energy.
cell can efficiently make use of all the available
energy.

the wavelength of light
enviromental Impact
Land use
larger utility-scale solar facilities can raise
concerns about land degradation and habitat
loss.
Total land area requirements vary depending
on the technology, the topography of the site,
and the intensity of the solar resource.
there is less opportunity for solar projects to
share land with agricultural uses.
enviromental Impact
Hazardous Materials
The PV cell manufacturing process includes a
number of hazardous materials, used to clean and
purify the semiconductor
surface.
Thin-film PV cells contain a number of more toxic
materials than traditional silicon photovoltaic cells.
If not handled and disposed of properly, these
materials could pose serious environmental or
public health threats.
