The growth of the solid-state cooling market is expected to be driven by the increasing demand for electric vehicles. Electric vehicles (EVs) are powered by electric motors and batteries instead of internal combustion engines. Their rising demand is fueled by environmental sustainability goals, lower operating costs, government incentives, advancements in battery technology, and expanding charging infrastructure. Solid-state cooling systems in EVs provide efficient thermal management without traditional refrigerants, improving battery life and performance through compact and reliable technology. For example, in 2024, the International Energy Agency (IEA), a France-based intergovernmental organization, reported that global electric car sales in 2023 approached 14 million, up 3.5 million from 2022, reflecting 35% year-on-year growth and increasing their share of total car sales from 14% in 2022 to 18% in 2023. Consequently, the growing adoption of electric vehicles is driving the expansion of the solid-state cooling market.

Major companies in the solid-state cooling market are focusing on advancing their product offerings, such as micro-multistage thermoelectric coolers (micro TECs), to enhance cooling efficiency and expand the applications of solid-state cooling technology. Micro-multistage thermoelectric coolers are devices that integrate multiple single-stage thermoelectric coolers in series, enabling them to achieve lower temperatures compared to single-stage devices. For example, in June 2023, Laird Thermal Systems, a US-based developer and manufacturer specializing in thermoelectric coolers, launched the OptoTEC MSX Series. This series of micro-multistage thermoelectric coolers is designed to be integrated into various optical packages such as TO-39, TO-46, or TO-8, creating advanced optical thermoelectric assemblies (TEAs). The OptoTEC MSX Series utilizes advanced ceramic materials, proprietary solder bonding techniques, and next-generation thermoelectric materials to increase cooling capacity by up to 10%, all within a compact micro footprint. Optical TEAs are specifically tailored for high-performance image sensing applications and are extensively used in analytical, industrial, and aerospace sectors. This innovation underscores Laird Thermal Systems' commitment to pushing the boundaries of solid-state cooling technology to meet the demanding requirements of modern industries.

In July 2024, Laird Thermal Systems Inc., a U.S.-based technology company, acquired Tark, Inc. for an undisclosed amount. Through this acquisition, Laird Thermal Systems aims to expand its thermal management portfolio and enhance its product offerings for advanced cooling solutions across various industries. Tark, Inc., a U.S.-based manufacturing company, specializes in providing solid-state cooling solutions.

Solid-state cooling is an innovative technology that utilizes solid-state materials, typically semiconductors, to achieve cooling effects without relying on traditional refrigerants, compressors, or moving parts found in conventional refrigeration systems. This technology exploits the Peltier effect, where an electric current passing through two different conductive materials (joined at two junctions) generates a temperature difference between these junctions, enabling heat transfer.

The primary types of solid-state cooling include single-stage, multi-stage, and thermocyclers. Single-stage systems are the most prevalent, featuring a single thermoelectric module that moves heat from one side to the other when an electric current is applied. This technology encompasses various methods such as thermoelectric cooling, electro-caloric cooling, and magneto-caloric cooling. It finds applications across diverse products including refrigeration systems, refrigerators, freezers, cooling systems, air conditioners, and chillers. Solid-state cooling serves a wide range of industries including medical, automotive, consumer electronics, semiconductors, and others, offering efficient and compact cooling solutions with potential benefits in energy efficiency and environmental sustainability.
