Abstract

Energy is undoubtedly one of our most important needs, whose consumption is constantly increasing and will

continue to increase in the future. Developing technology and increasing the number of people cause an increase

in energy needs. Many methods are used to handle the energy need. One of the most important factors in handling

the required energy is to provide high efficiency at a low cost. In this study, to overcome these energy problems,

the development of thermoelectric thin-film modules will be studied.

The thermoelectric effect is determined by measuring the electrical properties resulting from the temperature

difference between the two different types of materials. When a current is passed through a circuit composed of

two different metals connected, depending on the direction of the current, heat is absorbed from one of the metals

and released from another.

In engines, industrial processes, various boilers, and many other energy-consuming devices, the waste heat

released into the environment can be recycled and reused as clean energy. If waste heat recovery and management

are done correctly, more efficient and cheaper operation of systems in companies can be used to reduce operating

costs and greenhouse gas emissions.

For this purpose, thin films were grown on glass, Kapton tape and Si (100) substrates by using two different BiSeTe

/ BiSbTe alloy materials which are placed in industrial Peltier as a n and p-type semiconductor. The thermal

evaporation method has been used to develop thermoelectric modules nanoscale form. The thermoelectric

properties of n, p, and n-p cells obtained during this study were investigated by forming certain temperature

gradients on them by making serial connections. To find the temperature gradient, data, and images, a thermal

camera is used.
