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.

Homework Statement
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
 
Thread 'Minimum mass of a block'
Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...
TL;DR Summary: Find Electric field due to charges between 2 parallel infinite planes using Gauss law at any point Here's the diagram. We have a uniform p (rho) density of charges between 2 infinite planes in the cartesian coordinates system. I used a cube of thickness a that spans from z=-a/2 to z=a/2 as a Gaussian surface, each side of the cube has area A. I know that the field depends only on z since there is translational invariance in x and y directions because the planes are...
