Thermoelectric Materials and Devices
Power density is a measure of the amount of power generated per unit volume or area, often expressed in watts per cubic meter (W/m³) or watts per square meter (W/m²). It is crucial in evaluating the efficiency and effectiveness of thermoelectric systems, particularly in determining how well these devices can convert heat into electrical energy. High power density indicates that a thermoelectric generator or energy harvester can produce more energy in a smaller space, which is essential for optimizing performance in applications where size and weight constraints are significant.
