Extended Essay Research question help (first year IB student)

AI Thread 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.

I'm trying to come up with a research question to do my extended essay on.

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
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'A bead-mass oscillatory system problem'
I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
