Thermoelectric Generators: Design, Operation, and Applications

Abstract

This chapter offers a comprehensive analysis of thermoelectric generators (TEGs), with a particular emphasis on their many designs, construction methods, and operational processes, all aimed at achieving optimal conversion of thermal energy into electrical energy. This chapter extensively examines the fundamental principles that control thermoelectric generators (TEGs), providing a complete examination of their respective merits and drawbacks in comparison with conventional energy conversion techniques. This study thoroughly investigates the key elements that have a significant impact on the performance of thermoelectric generators (TEGs), including the temperature gradient, heat source temperature, and load resistance. Moreover, the chapter explores the diverse range of thermoelectric materials employed in these generators and their significant qualities that directly affect the efficiency and power output of the devices. TEGs have been widely examined in terms of their practical applications, which include waste heat recovery, space exploration, and remote power generation. This chapter provides a comprehensive analysis of the obstacles and prospects associated with the incorporation of thermoelectric generators (TEGs) into renewable energy systems. Additionally, it evaluates the feasibility of scaling up TEG manufacturing to meet growing energy demands, with a specific focus on promoting sustainable energy solutions.
