P2410901 - Characteristic Curves of a Solar Cell
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.

- Permet de limiter l’influence de la température et d’en mesurer quantitativement les effets.
- Permet de déterminer la relation entre le courant de court-circuit et l’intensité lumineuse.
Objectifs expérimentaux
- Déterminer l’intensité lumineuse à l’aide d’une thermopile pour différentes distances entre la source lumineuse et la cellule solaire.
- Mesurer le courant de court-circuit et la tension à vide pour différentes distances par rapport à la source lumineuse.
- Évaluer l’influence de la température sur la tension à vide et le courant de court-circuit.
- Tracer les caractéristiques courant-tension pour différentes intensités lumineuses.
- Étudier les caractéristiques courant-tension dans différentes conditions expérimentales : refroidissement à l’aide d’une soufflerie, absence de refroidissement et interposition d’une plaque de verre entre la source lumineuse et la cellule.
- Déterminer la caractéristique courant-tension de la cellule lorsqu’elle est éclairée par la lumière solaire naturelle.
