Round Clear Solar

First, you'll need to prepare some important elements to build your own solar cell. These elements are:

Copper or
or transparent Plexiglas / Perpex / Acrylic Plates
o Some fine wood Gaza
or copper wire
or Duct Tape
or metal guillotine
or band saw
or electric stove

To begin, cut a square of copper foil which is about 6-8 inches square size. It is much easier to do with a metal sash, however, if you do not have access to this type of equipment, tin snips work well.

After you've done that, wash your hands thoroughly and dry. You need to remove any grease or oil from your hands that could cause problems to the next step of the process. Remove any grease or debris from the copper plate. Then take a piece of emery cloth and sand in depth by the piece of copper on both sides to remove the top layer of oxidized copper. This will leave you with beautiful bright red shiny copper underneath.

Now you need to heat treatment of copper, to form an oxide layer on top. It may seem counter intuitive to just remove all the rust and now we're going to rust again, but the oxide layer is applied a film of oxide copper. "

You need to turn the burner to its highest position, with the copper strip just placed on top. Observe the changes in copper with care, are very interesting. As the heat of the copper, you need a beautiful patina living in different colors.

If you have access to acid Nitric can use this as a superior method to remove the top layer of cupric oxide.

You will see a black oxide scale on top copper plate. If you leave the iron to cool slowly, layer of crust should be fairly fragile and are easily separated from the underlying copper. When you have enabled the plate to cool completely, to the board of a company song bang a hard surface. Some of the oxides will fall away. Rub gently with fingers oxide under the tap, and you find most black oxide layer comes off easily od. If the bits are stubborn, not under any circumstances to go, she does not want damaging the fragile surface.

Under this layer of black oxide, is another layer of red rust orange color. This is the layer that is "photosensitive" and will leave thin film solar cell work.

Make a spacer now some thin strips of wood. Use tape to join their pieces of wood. Do not use metal anchors because it may react electrolytically with the other components of the cell.

We now are going to do the other electrode. Must have the property that do not touch the other part of the solar cell, and allows light to hit the surface. We will use salt water as our other electrode, networking with the entire surface of the thin film cell, however, it conducts electricity. We are then going to dip another copper wire to make the connection. You could also use another piece of copper plate around the outside of the thin film cell, but not touching our copper oxidized.

In a commercial cell thin film of tin oxide is commonly used as the other electrode, as is evident, yet conducts electricity.

Now take a piece Plexiglas to act as a cover plate, and stick adhesive strip on both sides.

We will maintain our other electrode wire to this piece Plexiglas.

The use of thick wire for clarity, with few real zigzags so you can see clearly what is happening. To optimize the performance of the solar cell, you want to do the CEO. To this end, it is best to use a lot of thinner gauge wire in a zig-zag pattern much thinner – this still allow light to pass, but at the same time providing a continuous surface large orchestra.

You can experiment with different types of and copper wire – the trick is trying to maximize the surface of copper, while trying to block the light as little as possible to reach the solar cell.
Double adhesive tape wire and attach to the plate.

Now we will combine the electrode plate with space. Again, duct tape makes this a nice easy job.

Then we will have the copper plate, and stick the tape to one side, with the sticky side of tape facing the same direction as the oxide layer red copper.

Combine the plate and the front module to finish the solar cell.

Now, take a little salt, and fill the void between the front section of Plexiglas and the copper plate. Stamp module with tape around it to prevent leakage.

Finally, connect the module a multimeter, find a source of bright light, and explore some of the electrical properties of the solar cell.
