Understanding the Seebeck Effect
The Seebeck effect generates a voltage in a material subjected to a temperature gradient, a cornerstone of thermoelectricity. The calculator quantifies this through the Seebeck coefficient and power factor, critical for assessing material performance. High S and PF values indicate efficient energy conversion.

Advanced Considerations
For accurate results, use experimental data from calibrated instruments (e.g., ZT meters). The calculator assumes linear behavior; non-linear effects (e.g., temperature-dependent conductivity) may require advanced tools like COMSOL. Cross-reference outputs with material databases like NIST for validation.
Case Studies
Example: For a material with V = 150 μV, ΔT = 50 K, and σ = 1000 S/m, the calculator yields S = 3 μV/K (low performance) and PF = 9000 μW/m·K² (promising), guiding optimization for thermoelectric generators.
