P2410901 - Courbes caractéristiques d’une cellule solaire
Reference : P2410901
Principle
The current-voltage characteristics of a solar cell are measured at different light intensities by varying the distance between the light source and the solar cell.
The influence of temperature on the open-circuit voltage and short-circuit current is also investigated.
Benefits
- Enables quantitative measurement of the solar cell characteristics while taking light intensity into account.
- Allows the influence of temperature to be minimized and its effects to be measured quantitatively.
- Enables the relationship between short-circuit current and light intensity to be determined.
Experimental Objectives
- Determine the light intensity using a thermopile at different distances from the light source.
- Measure the short-circuit current and open-circuit voltage at different distances from the light source.
- Evaluate the influence of temperature on the open-circuit voltage and short-circuit current.
- Plot the current-voltage characteristics at different light intensities.
- Investigate the current-voltage characteristics under different experimental conditions: cooling with an air blower, no cooling, and illumination through a glass plate.
- Determine the current-voltage characteristic of the solar cell when illuminated by natural sunlight.
