OverviewHistory

Conception

Classification

•In 1839 Alexandre Edmond Becquerel discovered the photovoltaic effect which explains how electricity can be generated from sunlight.•Around 1883 the first genuine solar cell was built by Charles Fritts.•In 1941, the silicon solar cell was invented by Russell Ohl.•Based on solar cell work of Russell Ohl, solar panels were made in 1955.

History

Conception•Devices that convert light into electricity• Solar panel is a collection of solar cells

• The more light that

hits a cell, the more

electricity it produces

solar cell

Conception

ClassificationBased on structure => 3 main types of solar panels

Monocrystalline silicon

Polycrystalline silicon

Amphorphous modules

Monocrystalline silicon (mono-silicon or single silicon)

Monocrystalline, as the name suggests, is constructed using one single crystal, cut from ingots.

Monocrystalline silicon (mono-silicon or single silicon)

Polycrystalline silicon (multicrystalline, multi-silicon, ribbon)

Polycrystalline (or

multicrystalline) modules

are composed of a number

of different crystals.

Amphorphous modules

The manufacture of these panels is highly automated - silicon is sprayed onto the substrate as a gas (called 'vapour deposition')

Advantages

•A renewable energy•Clear and non-

polluting

• No fuel costs or fuel supply problems

Advantages

•They are long lasting sources of energy which

can be used almost anywhere•Having long life time•Solar cell technology to generate thousands of

hours of electricity with minimal maintenance.

Advantages

Disadvantages•Solar cells and solar panels are very expensive

Disadvantages•Air pollution and weather can effect the production

of electricity•Solar power can not be obtained in night time

•Needing large

areas of land to

produce more

efficient power

ApplicationsRural electrification: the provision of electricity to

rural areas derive important social and economic

benefits.

Water pumping

Commercial

building system

Applications

Photovoltaic solar generators:

provide electrical

power to

satellites in an

orbit

Applications

Solar cells are also connected in series in

modules, creating an additive voltage

Applications

ApplicationsTelecommunication systems: radio transceivers on

mountain tops

Water pumping

Commercial
