Extended Essay Research question help (first year IB student)

Click For Summary
A first-year IB student is seeking help in formulating a research question for their extended essay, which requires a 4,000-word project. Initially interested in photoelasticity, they shifted focus to solar cells due to challenges in quantifying results. Suggestions include exploring the efficiency of solar cells in relation to temperature, which could lead to innovative hybrid systems. Additionally, incorporating mirrors with solar cells was proposed as a potential avenue for research. The student is looking for a straightforward research question to guide their experiments.

Homework Statement
I'm trying to come up with a research question to do my extended essay on.
Relevant Equations
No
Hi guys, I am a first year IB student and I need to give hand in my research question for the extended essay today, the only thing is that I don't really know what I could do it on. The extended essay is basically a 4000 word research project. I was going to do it on photoelasticity, but when I looked into the theory of it I saw that there wasn't much and also it was hard to quantify the experiments results. Now I'm thinking about a research question that has got something to do with solar cells. I'd like to formulate a hypothesis to my research question and then prove it with an experiment.

Does anyone have any ideas on what my research question could be (I'd prefer it to be more simple than complicated if possible)? Many thanks.

Welcome to PF.

Maybe look into the efficiency of solar cells versus their temperature? This can be important if you want to use some sort of temperature control on the cells to improve their efficiency. It can also lead to hybrid solar cell systems that do some other function as well... :wink:

What solar cells are you planning to get? How would you measure their efficiency.

You could elaborate with mirrors and solar cells
 
Thread 'Correct statement about size of wire to produce larger extension'
The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
