ABSTRACT:
A thermoelectric alloy composition is described comprising from 5% to 95% silicon, from 95% to 5% Germanium, from 0.01% to 0.2% lead and from 0% to 0.2% tin, all percentages being atomic percentages. In a preferred composition at least 50% silicon and 50% Germanium is present with 0.03% to 0.1% lead and from 0 to 0.05% tin. Tin and lead in combination provide lower thermal conductivity and a greater figure of merit than with lead or tin alone. Other preferred compositions are provided and a thermoelectric material and a p-n coupling thermoelectric generator (10) incorporating the alloy is disclosed. The alloy composition provides high efficiency of power to heat loss and minimizes running costs.
