Solar energy – nuclear fusion in the sun

0 Solar energy   nuclear fusion in the sunHow nuclear fusion works in the sun and how photons from this fusion provide us with solar energy here on Earth for things like photovoltaics (solar power), solar domestic how water, solar air heating and solar cooking. Also given is background such as what an atom is and the parts of an atom: neutrons, protons and electrons. Sample atoms are provided: hydrogen, deuterium and carbon atoms.

This is the simplified version that stops at gravity. Version 2 of this video goes into more detail talking about gravity, high temperatures and quantum tunneling: Solar energy   nuclear fusion in the sun

What are the advantages of using gallium arsenide in solar cells or solar power panels?

i need to know this immediately. It is said that gallium is rare than gold, so even if it is rare than gold what it got to do with advantages?

They have a higher energy conversion efficiency in white light than silicon cells do.

So if cost is not important, but area for cells is very limited, then GaAs cells are better.

Stacking several different cells on top of each other (where the wavelengths that are not converted are passed through to a material that will convert some of what is left to electricity) are best and are called multi-junction cells. The Mars Rovers use these.

The distribution of solar energy power plants?

im doing a project for geography about the renewable resources. Mine is solar energy and one of the question was that i need to find the distribution of power plants of the assigned source (solar energy). I searched every , but i cant find any decent info. plz tell some good websites thx

Here’s a good start, with links to articles about specific plants, and articles with more info:

Relationship between number of solar cells and power out?

I’m trying to find the relationship between the number of solar cells and power out, in a lab-size experiment, with the solar cells connected in parallel and series. Is the relationship linear or logarithmic?

If you get to choose the load for maximum power out, then the power out should be linear with the number of cells.

Think of a solar cell as a constant current source, with the limitation that it will not exceed a certain voltage. So if you’re getting maximum power out with a load of L ohms, if you have 2 series solar cells, you should have a load of 2L for max power out. Or, with 2 parallel cells, a load of 0.5 L.

what are the most profitable field when it comes to renewable energy is solar power?

the most profitable field when it comes to renewable energy is solar power. It seems as if the biggest “controversy” regarding solar power is the amount of space required for the solar panels to capture the solar energy which is converted to electricity.

While size matters PV systems rule the market
