STEGs are devices that convert sunlight into electricity by using the temperature difference between a hot and cold side to generate a voltage. The efficiency of STEGs depends on the thermal conductivity of the materials used in their construction. Lower thermal conductivity means higher temperature difference and higher voltage. Nanotechnology can help develop materials with lower thermal conductivity and enhanced thermoelectric properties, such as nanocomposites and nanostructured materials. Nanotechnology can also help improve the optical properties of the materials used in STEGs, such as applying nanoparticles to the surface of a solar absorber to increase its sunlight absorption. Nanotechnology has the potential to boost the efficiency and practicality of STEGs, which could lead to a cleaner and more sustainable energy future.
