3.1.3 List of experiments
(1) Series and parallel connection of solar cells
Our technology allows only for the production of solar cells with a limited surface. In today’s mass
production crystalline silicon solar cells are manufactured with a surface of 12x12 cm2. The voltage of such a cell
is limited to 0.6V. These low voltages are hardly useful for technical applications. Therefore several solar cells are
connected together to units. In most cases commercially available modules feature a 6V nominal voltage.
(2) Dependence of the power on the surface of the solar cell
(3) The dependence of the power on the angle of incidence of the light
This experiment can be used to determine the following physical values in dependence on the incidence of
light α:
(a) Short-circuit amperage IK;
(b) Open-circuit voltage UL;
(c) Power at a fixed load.
3.1.4 Application: Tracking of solar cells
To achieve a high energy efficiency at the utilisation of solar cells, large solar plants track the sun, this
