Web2 days ago · The Seebeck coefficient ( S ), characterizing the output power, is a particularly important parameter for conversion efficiency of TE materials. In the past 200 years since the Seebeck effect was discovered, researchers have tried various ways to increase S to increase the TE performance of materials. WebThe Seebeck coefficient(also known as thermopower,[1]thermoelectric power, and thermoelectric sensitivity) of a material is a measure of the magnitude of an induced thermoelectric voltage in response to a temperature difference across that material, as induced by the Seebeck effect.[2]
Web11 May 2024 · The Seebeck coefficient of NbCo 1.3 Sb was approx. −70 μV K −1 at room temperature and ~ −154 μV K −1 at 973 K. The Seebeck coefficient enhanced gradually with increasing excess Co content, which could partly be explained by a decreasing Hall carrier concentration ( Table 2 ). WebThe enhancement in the Seebeck coefficient is ascribed to the dipole moment of Rhodamine 101 and the interfacial dipole moment formed at the surface of the …
