The thermoelectric module market size is expected to see rapid growth in the next few years. It will grow to $1.2 billion in 2029 at a compound annual growth rate (CAGR) of 11.3%. The projected growth during the forecast period is expected to be driven by increasing demand for precision cooling in electronics, wider use of thermoelectric modules in automotive applications, growing adoption of electric vehicles, rising interest in solid-state refrigeration, and expanding demand for off-grid power generation. Key trends anticipated in this period include advancements in energy harvesting technologies, development of miniaturized module designs, innovations in solid-state cooling solutions, integration of thermoelectric modules into wearable devices, and improvements in automotive thermal management systems.

The expansion of the electric vehicle (EV) market is expected to propel growth in the thermoelectric module market. EVs are vehicles powered fully or partially by one or more electric motors using energy stored in rechargeable batteries, rather than relying solely on internal combustion engines. The market for EVs is growing due to increasing environmental concerns, as they provide a cleaner alternative to traditional fossil-fuel-powered vehicles by reducing greenhouse gas emissions and air pollution. Thermoelectric modules enhance EV efficiency by converting waste heat from the battery and motor into usable electrical energy, improving overall energy management and extending driving range. For example, in January 2024, the US Energy Information Administration reported that in 2023, combined sales of hybrid, plug-in hybrid, and battery electric vehicles represented 16.3% of total U.S. light-duty vehicle sales, up from 12.9% in 2022. Consequently, the growth of the electric vehicle market is driving the expansion of the thermoelectric module market.

Key players in the thermoelectric module market are developing advanced solutions such as thermoelectric cooling systems to enhance thermal management and reliability across diverse applications. Thermoelectric cooling systems use semiconductor materials to precisely control temperature, providing improved thermal performance and dependability for applications including laser stabilization, sensor cooling, and medical storage. For example, in January 2025, Coherent Corp., a US based manufacturing company, introduced the CT Series thermoelectric coolers designed for high performance and cost effective thermal management. These coolers deliver exceptional temperature differentials of over 70 degrees Celsius at 27 degrees Celsius and up to 80 degrees Celsius at 50 degrees Celsius, ensuring precise thermal control. Built for durability, they can withstand up to 100,000 thermal cycles, making them suitable for demanding applications while remaining compatible with existing systems.

In June 2022, Yamaha Corporation, a Japan based thermoelectric power generation module company, partnered with Sumitomo Corporation Power and Mobility Co., Ltd. to demonstrate an on board thermoelectric generator system. The collaboration aims to capture waste heat through thermoelectric generation to improve vehicle energy efficiency and reduce carbon emissions. Sumitomo Corporation Power and Mobility Co., Ltd. is a Japan based company that develops and provides advanced mobility systems and social infrastructure solutions.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid rise in U.S. tariffs and the subsequent trade frictions in spring 2025 are having a major impact on the electrical and electronics sector, with semiconductors, display panels, and rare-earth metals (essential for batteries and motors) subject to steep duties. Consumer electronics brands face profit erosion, as competitive markets limit their ability to pass costs to buyers. Industrial electronics manufacturers, meanwhile, grapple with delayed projects due to shortages of tariff-impacted components like printed circuit boards. Companies are responding by relocating assembly to tariff-exempt countries, increasing inventory buffers, and redesigning products to reduce dependency on restricted materials.

A thermoelectric module (TEM) is a solid-state device that converts heat into electrical energy or electrical energy into heat by utilizing the Seebeck and Peltier effects. It is composed of semiconductor materials sandwiched between two ceramic plates to create a temperature gradient. TEMs provide efficient cooling, heating, or power generation without moving parts, offering high reliability and low maintenance requirements.

The primary types of thermoelectric modules include bulk, micro, and thin-film modules. Bulk thermoelectric modules are solid-state devices made from bulk semiconductor materials that generate electricity from heat or provide cooling via the Seebeck and Peltier effects, ensuring dependable thermal management. These modules use materials such as bismuth telluride, lead telluride, silicon-germanium, and half-Heusler alloys, and are available in single-stage and multi-stage configurations. They serve a wide range of applications across energy and utilities, aerospace and defense, automotive, consumer electronics, healthcare, food and beverage, and other industries.
