Электрические характеристики термовольтаического элемента на основе сульфида самария

The converter of thermal energy into electrical energy based on the thermovoltaic effect is considered. Samarium sulfide (SmS) samples obtained by high-temperature sintering were used as working material. The main electrical characteristics of the thermovoltaic element based on the thermovoltaic effect are determined: volt-ampere characteristic, maximum power, internal resistance. It is shown that the optimal load to obtain maximum power is equal to the internal resistance of the element.
