focused mainly on thermoelectric generator and different technologies which is
used on thermoelectric generators. It includes how thermoelectricity is better
than other solar based technology to make electricity. But there is a drawback
of thermoelectric generators of its low efficiency or low figure of merit. In
this review, different methods are presented to obtain a higher satisfactory
efficiency. There is easy solution to gain this higher efficiency with the help
of material changing properties and waste heat recovery on the both side
junction of thermoelectric module.

have been observed that the electrical power generation of the thermoelectric
generator is observed to be a strong function of flow rate and inlet exhaust
temperature. The temperature difference between the hot and cold junctions of
TEG increased as the engine speed or the coolant temperature increase. The
output voltage, according to the Seebeck effect, also increased as the
temperature difference increase. Therefore, the output power and thermal
efficiency can be improved. The parametric evaluation of the longitudinal model
indicates that TEG performance improves for configurations that have minimum
TEG height and maximum TEG width. The high-efficiency heat exchanger is
necessary to increase the amount of heat energy extracted from the exhaust gas.
It is found that exhaust gas parameters and heat exchanger structure have a
significant effect on the system power output and the pressure drop. The study
also identified the potentials of the technologies when incorporated with other
devices to maximize the potential energy efficiency of the vehicles.
generated a novel concept of the power generation from waste heat using a
combination of heat pipe and thermoelectric generator with investigations into
key performance parameters such as maximum power output and heat transfer rate.
The experimental result shows that an increase in the ratio of mass flow rate
in upper duct to lower duct has a positive effect on the overall system
performance. A higher mass flow rate ratio results in a higher amount of heat
transfer and greater power output.
