Thermoelectric power generation (TEG) devices typically use special semiconductor materials, which are optimized for the Seebeck effect. The simplest TEG device consists of a thermocouple, comprising a p-type and n-type material connected electrically in series and thermally in parallel.
Heat is applied into one side of the couple and rejected from the opposite side. An electrical current is produced, proportional to the temperature gradient between the hot and cold junctions.

To design a project that could be used to utilize the waste heat energy into electricity for multipurpose use in various applications and household purposes. This system should be economical, easy to implement and does not produce any kind of pollution, it is silent and does not require any kind of fuel to work. The main feature of this project is that it converts direct temperature difference into electricity. It is based upon thermoelectric energy generation concept and has many applications in electricity generation from automobile waste heat, heat liberated from household items, electricity generation from glaciers (ice) and a lot of similar applications where temperature difference from environment is converted into electricity. This concept is very useful in terms that it adds up to other renewable sources of energy and can be used in place of other non-conventional sources of energy like wind, solar, tides, geothermal heat, etc. This is a new concept for electricity generation using temperature difference between junctions of a peltier element to be used in our project. The complete Thermo Electric Generator would be based on Seebeck Effect that is reverse of peltier effect.

This ppt is made for making the topic clear. The aim is to make available content regarding thermocouple which is available on various sites. This ppt is made only for study purposes. The author doesn't claim originality of the content.
The thermocouple can be defined as a kind of temperature sensor that is used to measure the temperature at one specific point in the form of the EMF or an electric current. This sensor comprises two dissimilar metal wires that are connected together at one junction. A Thermocouple is a sensor used to measure temperature. Thermocouples consist of two wire legs made from different metals. The wires' legs are welded together at one end, creating a junction. The voltage can then be interpreted using thermocouple reference tables to calculate the temperature.The temperature can be measured at this junction, and the change in temperature of the metal wire stimulates the voltages. These are used as the temperature sensors in thermostats in offices, homes, offices & businesses.
These are used in industries for monitoring temperatures of metals in iron, aluminum, and metal.
These are used in the food industry for cryogenic and Low-temperature applications. Thermocouples are used as a heat pump for performing thermoelectric cooling.
These are used to test temperature in the chemical plants, petroleum plants. These are used in gas machines for detecting the pilot flame.

Energy related cost have become a significant fraction of cost in any industry. The three top operating expenses are often to be found in any industry like energy (both electrical and thermal), labour and materials. If we were found the manageability of the above equipment's the energy emerges a top ranker. So energy is best field in any industry for the reduction of cost and increasing the saving opportunity. Thermoelectric methods imposed on the application of the thermoelectric generators and the possibility application of Thermoelectrity can contribute as a "Green Technology" in particular in the industry for the recovery of waste heat. Finally the main attention is too focused on selecting the thermoelectric system and representing the analytical and theoretical calculation to represent the Thermoelectric System.

Thermoelectric Refrigeration System Running On Solar Energypaperpublications3
Abstract: The global increasing demand for refrigeration in field of refrigeration, food preservation, storages, medical services, and cooling of electronic devices, led to production of more electricity and consequently more release of CO2 all over the world which it is contributing factor of global warming on climate change. With the increase awareness towards environmental degradation due to the production, use and disposal of Chloro Fluoro Carbons (CFCs) and Hydro Chlorofluorocarbons (HCFCs) as heat carrier fluids in conventional refrigeration and air conditioning systems. Thermoelectric refrigeration is new alternative because it can convert waste electricity into useful cooling, is expected to play an important role in today's energy challenges. It does not require working fluids or any moving parts, which is friendly to the environment and it simply uses electrons rather than refrigerants as a heat carrier. Continuous efforts are given by researchers for development of thermo electric materials with increase figure of merit may provide a potential commercial use of thermoelectric refrigeration system.
In this work it has been identified that there is enormous scope to develop TER system running on solar energy and its performance evaluation along with mathematical modeling. Mathematical results can be correlate by performing experimental test set up. Present paper especially focuses on evaluation of numbers of thermoelectric cooling module; heat sink fan assembly for each module which is used to increase heat dissipation rate and time required for attaining the cooling of heat sink fan assembly after a solar power is applied.

4. The thermoelectric cooling is used as renewed
technology, has made an impact in the field of
alternative refrigeration. The common principle
is the presence of coupled electrical and
thermal currents, so that it is possible to use the
effects to generate power from a temperature
differential.
Thermoelectric cooling provides an alternative
solution to the common compressor and
absorber cooler. Thermoelectric coolers are
used especially if small cooling power is
5. Thomas Seebeck in the early 1820’s found that
a voltage difference is generated between the
hot and cold ends when certain materials are
placed in a temperature gradient.
This phenomenon is popularly known as
Seebeck effect.
6.
7. Depending on the used heat exchangers the
cooling units are distinguished:
air to air
air to fluid
fluid to fluid
direct to air (cooling plate to air)
8. small size
light in weight
no fluid
independent from the working position
high reliability
exact temperature control
heating by changing the direction of the current
9. The basic principle behind thermoelectric effect is
peltier effect it occurs whenever electric current
flows between two dissimilar conductors,
depending on the direction of the current flow, the
junction of the two conductors will either absorb or
release heat.
A thermoelectric material is made of two legs, one
of which is ‘n-type’ and contains negatively charged
mobile carriers in the form of electrons while the
other leg is ‘p-type’ and contains positively charged
mobile carriers known as holes. These two legs are
connected electrically in series and thermally in
parallel.
10. By connecting 2 wires of different electrically
leading materials at the 2 ends and by applying
additionally a voltage, a current flows, which
transports heat of one junction point to the other.
In the consequence one junction point becomes
cold and the other one warm.
For thermoelectric modules materials are applicable
with a high electrical conductivity and a small thermal
conductivity. Unfortunately good electrical conductors
are also good heat conductors. The best efficiency is
obtained with semi-conductors
11. Unfortunately good electrical conductors are also
good heat conductors. The best efficiency is obtained
with semi-conductors.
12. If temperature difference is created between two
different conductors, ‘a’ and ‘b’ having junctions at
M and N, a voltage difference (V) will be created
between M and N appearing between the two ‘b’
segments Therefore, under open-circuit.
13. On the hot side the net heat from the cold side and
the power required to pump this heat must be
transferred to the environment.
Qh = Pel + Qc
By changing the direction of the current the heat
flow changes too, from the cooling mode into the
heating mode.
