Abstract

The concept of a Peltier effect is a direct current that through the connection of two thermoelectric materials can produce a temperature difference at the end of the connection. The thermoelectric element functions as a means of converting electricity to thermal / heat which uses the concept of Peltier law, known as thermoelectric type TEC (thermoelectric cooler). The use of thermoelectric elements for electricity generation by changing thermal/heat into electricity is the concept of Seedback effect, which is applied to the TEG type thermoelectric element (Thermoelectric Generator). Both thermoelectric element types are capable of changing thermal/heat into electricity and vice versa. This study aims to analyze the thermoelectric capability of TEC and TEG types as thermal/heat converters into electricity. Experimental testing by heating and cooling on each side of the TEC and TEG type thermoelectric elements is carried out to obtain voltage and electric current values with variations in the load using resistors so that electric power can be calculated so that the characteristics (power) of the element are known. The term regulator is set at a difference of 70 ° C between elements. This study resulted in the highest resistor loading value at 10 kΩ produced the highest power in the TEG type thermoelectric, with a difference of 0.00011 watts and proved TEG was more effective with the same working temperature against TEC, as a power plant (thermal-electricity). With the highest voltage and electric current, the TEG is 1.48 V and 0.00141 A
