   High-reliability thermoelectric Peltier modules have been developed by using Bi-Te-Se-Sb solid solutions of rated mechanical strength, and by application of antidiffusion layers formed on thermoelements' arms, adhesive strength thereof being a value of o_p >=80 МПа, o_n >= 100 МPa at Т = 300 K, and also by plating ceramic plates with a molybdenum-copper pseudo-alloy. TEM parameters' values of the thermoelectric modules developed do not change upon effect of ultimate temperatures in the range from 213 K to 333 K, electric load in cyclic (1500 hours) and continuous (2000 hours) modes, influence mechanical and climatic factors
