Electric energy generation with a thermogenerator

Principle

The thermogenerator consists of a block with multiple thermostats. These are connected electrically in series and thermally in parallel, so that their thermoelectric voltages add up.

Water baths can be used to bring the two sides of the thermogenerator to di ...

Heat insulation / heat conduction

Principle

A model house with replaceable side walls is used for determining the heat transition coefficients (k values) of various walls and windows and for establishing the heat conductivities of different materials. For this purpose the temperatures on the i ...

Characteristic curves of a solar cell

Principle

The current-voltage characteristics of a solar cell are measured at different light intensities, the distance between the light source and the solar cell being varied. The dependence of no-load voltage and short-circuit current on temperature is determined.
