Hi Justatruthseeker, Thank you for your responses, amazing to see that someone found this nearly 3 years after it started. I haven't heard of Marklund convection before, that's definitely something I'll look into. Thanks again, -Physicist50

Oh yeah, my mistake, sorry for any confusion, and thanks for the suggestion of tandem cells. I'm still wondering about my original problem though, would it work to increase the compliability of photons with the solar cell by lowering their wavelength (and not the energy as I just learned)?

Fair enough, although to my knowledge few materials that conduct the photoelectric effect can utilise more energetic photons. My research also told me that the ideal wavelength for converting to electricity was 700nm, any higher and some already start to pass through, and at around 1100nm they...

Oh right, I meant *photons that are most present in the atmosphere, sorry for any confusion. On another point, yes the photons lose energy, but is that not the intention? So as to lower the most abundant frequency of photon to the optimal energy where all is absorbed without being too energetic...

Alright... but my research implies that I would need to lower the energy of photons that make up most of the atmosphere, thus increasing the amount of light received with the perfect amount of energy, so is decreasing the energy not a good thing in that case? Assuming, of course, that said...

Ah, I understand more now thank you. So that begs another question only vaguely answered by Google. Is there a practical way to decrease the energy (frequency, not wavelength as I recently found out) of photons? But also, is frequency still not decreased in the scenario of flint glass on solar...

Thanks for all this, and of course you've made a good point with the reflection. Just a few things though; firstly, it's my understanding that frequency and wavelength are inversely proportional, so if someone could explain the difference as parameters for solar cell efficiency between them that...

Hi there, I have recently been researching in depth solar cells/panels, the parameters of their efficiency and the photoelectric effect in general, specifically how different wavelengths of light affect it. My research has yielded a few facts; that the efficiency of standard silicon solar cells...

Thanks Simon Bridge, but I'm still not sure I understand. Why would the weight of Helium affect how it reacts to magnetic fields? Sure, it affects how it reacts to gravity differently, but to my knowledge the two phenomena are not related.

Hello everyone, I was recently creating two different types of plasma for a Science Fair, one created from ionised Helium, (although it's the party balloon stuff, and I hear there's some Oxygen in them) and the other was created from air. I was testing how the plasmas reacted to magnetic fields...

You're right, Sciencekid, schools probably should teach you about the five states of matter. Even if not Bose-Einstein Condensates, at least plasma, seeing as it's such a common phenomena

Thanks TheSatirist, you probably gave about 10 cents there, not just 2

Hi everyone, I am about to enter a local Science Fair and my project revolves around creating plasma in a microwave. This is a great experiment, all you do is stick a lighted match in a cork, (or something to hold the match in place) put it in the microwave with a glass beaker over the match...

Wow, thanks maxime.lesur!

Good point, but I really need to know how to turn a newly ionized plasma into a filament in the first place. Explanations, calculations or references of how to do this is perfect.
