Accurate measurement of efficiency for thermoelectric generator (TEG) is ofgreat importance for materials research and development. Approximately all theparameters of a material are temperature dependent, so we can't directly applythe $\eta_\text{max}$ formula for efficiency calculation in the largetemperature range. To overcome that problem, we tried to calculate theefficiency of TEG by dividing large working temperature range into a number ofsmall temperature difference. The aim is to make temperature dependentparameter to be constant for that small temperature range. Using maximumindividual efficiency of each segment obtained by $\eta_\text{max}$ in theequation of $\eta_\text{overall}$, which gives overall efficiency. The$\eta_\text{overall}$ of TEG using $Bi_2Te_3$ and $TAGS$ as thermoelectricmaterials come out to be $7.1\%$ and $8.94\%$, respectively, which is close toexperimental results. For the high-temperature region, we have used $SiGe$material in TEG and found out $\eta_\text{overall}=3.5\%$. The cumulativeefficiency obtained by keeping one end temperature fixed with another endvarying can be applied in real life application, i.e. automobile sector. Thepresent work provides a simple way for the design engineers to calculate theefficiency of TEG by using the temperature dependent materials parameters likethermal conductivity, electrical conductivity, and Seebeck coefficient on which$z\bar{T}$ depends.
