Characteristic curves of a solar cell

Product No: P2410901

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.

Tasks

To determine the light intensity with the thermopile at various distances from the light source.
To measure the short-circuit current and no-load voltage at various distances from the light source.
To estimate the dependence of no-load voltage, and short-circuit current on temperature.
To plot the current-voltage characteristic at different light intensities.
To plot the current-votlage characteristic under different operating conditions: cooling the equipment with a blower, no cooling, shining the light through a glass plate.
To determine the characteristic curve when illuminated by sunlight.
