Abstract
The disclosed invention includes improved devices and materials for thermoelectric conversion, particularly for operation at temperatures of 300.degree. C. and below. Disordered p-type semiconductor elements incorporate compound adjuvants of silver and lead to achieve enhanced 'figure of merit' values and corresponding increased efficiencies of thermoelectric conversion. Similar results are obtained with disordered n-type elements by employing lowered selenium contents, preferably in combination with cuprous bromide. Improved conversion devices include powder pressed elements from one or both of these materials.
