Effective parameters of a cascade thermopile

For the description of the working characteristics of a multicascade thermopile equations are proposed which are simple in their mathematical structure, and in which the physical properties of the individual cascades are replaced by effective parameters, giving a concept about the properties of the chain of cascades as a whole. Calculation formulas are given for the calculation of effective parameters based on the results of tests of a cascade thermopile. The physical meaning of the effective parameters is discussed and their interconnection with the properties of the individual cascades is shown.
