Final answer:
To determine the impact of light intensity on solar cell output, an experiment can be conducted by varying the intensity of light falling on a solar cell and measuring the corresponding output. By analyzing the data, the relationship between light intensity and solar cell efficiency can be determined.
Step-by-step explanation:
The question the students were investigating is: b. What is the impact of light intensity on solar cell output?
To determine the relationship between light intensity and efficiency, an experiment can be conducted by varying the intensity of light falling on a solar cell and measuring the corresponding output. The procedure would involve setting up a solar cell and a light source, such as a lamp, at a fixed distance. Then, the light intensity can be adjusted by changing the distance between the light source and the solar cell or by using different power levels of the lamp. The output of the solar cell, usually measured in terms of voltage or current, can be recorded at each light intensity level. By analyzing the data, the impact of light intensity on solar cell output can be determined.
