Unfortanty because it’s a new type of business, everything is expensive. Solar cells will take about 10 years to pay for it’self, wind I belive is 7, and hydrogen (the ones you put water in and it generates power and of course oxygen are the most expensive.

But for that hydrogen he’s a website below.

The small house windmill, according to where you live, = how much energy it will produce (it’s size) and your own uses, you can sale some to the grid, but this is so new (alt power) they can’t give you a diffanate – so don’t belive the salesman, no one really knows so what would make anybody think they actually know.

The 2nd lnk below is what I personaaly be the best method so far, in the fiels of Alt power. Thing is it’s new, and so you will have to follow his work, at Davis Univ, but the money they bring in goes to get the generators on the market – its cheaper than all of the other types I mentioned above = it mimics the way plants and water get its energy from the sun, to produce energy.

Basically what goes on in a solar cell is the conversion of light energy (photons) to electrical current (the flow of electrons).

In physics this is called the photoelectric effect.

A solar cell will absorb light energy (the photons, which could be visible light, UV light or IR light generally), and this light energy will energize electrons in the atoms of the cell.

These electrons will cause a charge separation (positive and negative) in the material (a voltage) which will have a mechanism for trapping the electrons to maintain the voltage.

Current will then flow if you connect the separate charged ends of the cell with a conductive material.

I am not sure how to make it simpler…

The cell works the same as a silicon wafer or any other solar cell.

When photons strike the surface, an electron in the Cu(II) oxide plate is promoted to a higher electronic state in the conduction band,

Being attached to free Cu, electrons in thier conduction band allows the electrons mobility and flow as current when there is a circuit load. Drawing off this current leaves holes n the Cu conduction band.

See. Electrons in the atoms of each material reside in bands, much like the floors in a “two story” building with a flat roof. When light strikes the electrons, they gain energy and are promoted to the roof, where they can move around (conduction) . Siphoning off these electrons (electrical load) leaves more room on the roof, for more electrons to be promoted from below.
