    • 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.
    • 所公开的发明包括用于热电转换的改进的装置和材料,特别是用于在300℃及以下的温度下操作。 无序的p型半导体元件掺入银和铅的化合物佐剂,以实现增强的“品质因数”值和相应提高的热电转换效率。 通过使用降低的硒含量,优选与溴化亚铜组合,用无序的n型元素获得相似的结果。 改进的转换装置包括来自这些材料中的一种或两种的粉末压制元件。
