Principle
With the aid of a solar cell, solar
energy can be converted into electrical energy. This is a very
important form of energy, not only for the household but also for
industrial applications, since it can be easily converted into
other forms of energy, e.g. heat, light, or mechanical energy
(motion). In this experiment, a small electric motor is driven by a
solar battery. The experiment consists of two parts. In the first
part, the electric power and work are measured simultaneously at
different light intensities in order to demonstrate the
relationship between the two quantities and to evaluate it in a
quantitative manner. At high light intensities and long lighting
periods, the solar cells heat up and their power decreases. This
effect can be demonstrated in the second part of the
experiment.
Benefits
- Part of a system solution - Easily expandable for further experiments
- easy teaching by using the demo board for demonstration
- Simplified implementation: all pre-settings already prepared
