Photo voltic cell experiment

Hii..!

Project name:-
Photovoltaic cell Experiment.
Hypothesis of the Project:-
Hypothesis for this series of experiments was the the larger the distance of the source from the cell, the less power it would produce due to the fact that it would receive less energy(since light would be emitted in more directions.
Procedure:-
Set up the cell in the desired distance from the light source(the distances used in this series were 0,4,8 and 12 inches away from the light source.)The cell was connected to our computer and gave us readings of the power it produced. Then, after the data was put in excel we determined the average of each distance-reading.
Data Analysis:-
As we can see from the above data, our hypothesis was completely verified since increasing the distance from the source decreased the power output. Furthermore, the graph produced shows a negative exponential(since the graph is not linear) relationship between the distance and the voltage output. If i had to guess i would say that the function would be of the form of y=1/x or y=1/x^2. However, more data is needed to determine the exact relationship between the two variables.
Conclusion:-
As we saw from the above information our hypothesis was verified and the power output of the cell decreases as its distance from the light source increases. All in all, even though we calculated some average values in our experiments, i do not think that they hurt the accuracy of our results significantly which makes the experiment a success as far as i am concerned. An area that we could have improved would have been the holding of the cell(which we did manually by hand) so as to negate the effects of our unsteady hands. As i said though, the effect of this error is insignificant and does not interfere with our results.
