P2410700 – Semiconductor Thermogenerator – Seebeck Effect
Reference : P2410700
Principle
In a semiconductor thermogenerator, the open-circuit voltage and short-circuit current are measured as a function of the applied temperature difference. These measurements are used to determine the Seebeck coefficient, internal resistance, and energy conversion efficiency of the thermogenerator.
Benefits
- Open design provides a clear understanding of the system's operating principle and applications.
- Individual instruments are used for specific functions, avoiding a “black box” approach.
- The key components of the experimental setup can also be used to investigate the Peltier effect.
Experimental Tasks
- Measure the open-circuit voltage U0 and short-circuit current Is at different temperature differences, and determine the Seebeck coefficient.
- Measure the current and voltage at a constant temperature difference using different load resistors, and determine the internal resistance Ri from the measured values.
- Determine the energy conversion efficiency from the amount of heat consumed and the electrical energy produced per unit of time.
