Представлено методику характеристики термоелектричних перетворювачів енергії на основі дослідження частотної залежності їх імпедансу. Розроблено спеціалізовані апаратно-програмні засоби для імпедансної спектроскопії термоелектричних модулів. Для аналізу отриманих спектрів за основу взято електротермічну модель, яка добре описує експериментальні результати та дозволяє отримати не тільки електричні але і теплові характеристики термоелектричного перетворювача енергії.
