Description
Illuminance, temperature and electrical load are the key variables affecting photovoltaic solar cells. It allows you to conduct targeted experiments in order to understand the basic principles and practically relevant effects on cells and modules.
Four solar cells are illuminated by a lamp field with adjustable illuminance. They can be precisely maintained at a selectable set temperature thanks to a regulated Peltier module. Using the set of cables provided, the cells can be interconnected in a number of ways, via a patch panel. For example, individual cells can be bridged by bypass diodes in order to examine differences in power loss such as caused by shaded cells.
A rheostat is integrated into the patch panel to manually record current-voltage curves. Current and voltage measurements are detected via the built-in measuring unit. Automated measurements can be taken by software by specifying electrical load patterns.
