THE COPPER CHLORINE SOLAR CELL: Buy a roll of Thin Copper sheeting, cut a 1.5" diameter piece out with a pair of cutters, then sand polish the copper on both sides with some fine grade steel wool. then by using a propane torch heat the copper while griping it with rubber handled pliers, and let the copper get red hot, until it glows, move the copper over the flame evenly for about 3 minutes then allow to cool slowly. Then once it is cooled dip it down in an acid solution of 1/2 water and 1/2 acid, WARNING! Never pour water into acid always pour acid into water. The acid that you can use is MURIATIC ACID ( Hydrochloric Acid ) you can buy it at any hardware store, or you can use a solution of nitric acid. REMEMBER TO WEAR PROTECTIVE
GOGGLES OR OTHER SUITABLE EYE PROTECTION, AND WORK IN A WELL VENTILATED AREA. DO NOT SMELL THE FUMES OR MAKE CONTACT WITH YOUR SKIN, WEAR RUBBER GLOVES. THESE ACIDS CAUSE SEVERE BURNS. KEEP OUT OF THE REACH OF CHILDREN. NOTICE: WE ARE NOT RESPONSIBLE FOR ANYTHING IN THESE PLANS , YOU BUILD AND EXPERIMENT AT YOUR OWN RISK.
Keep it in the acid for only a half a minute or longer, the idea is to keep it dipped in the acid long enough for the black oxide to come off of the top layer, under that is the photo sensitive red cuprous oxide. Remember you should only have a dark bright red layer left. Note: do not leave it in to long it will eat away the red. once you have done that then it's O.K. to wash off the acid with water, do all of this outside or in your garage, make sure all of the acid is off. wash no less than 3 minutes, now look at the copper disk on one side you will have bright copper, this is the positive side, and on the other side you will have red this the negative side the side you face toward the sun. now mix a small solution of 95 water and 5 Clorox bleach, now take the red side and look for
scratches if there are any you must paint them with enamel oil base paint, apply paint to any where on that side where copper is showing through, now glue a plastic lid on to red side, let it dry them drill a small hole in the top pour in Clorox bleach and water solution and then place a copper or steel wire through the hole and onto the bottom, wire must be submerged in the solution, now tape or glue the hole up with the wire in it. now tape
Solar cell out into the sun and using a DC volt meter attach + to the copper back, and - to the steel wire coming out of hole. you will see the meter move showing a voltage, now block the sun with your hand and watch the voltage drop.
make many of these for just pennies and put them in series or parallel to increase your voltage or amperage. These type of cells are only 5 of the japan cells.
I have heard that the Japanese cells are about 95 of the American made silicon cell that is a very expensive process. Screen printing them is the cheapest way to go and is easy, once you get the hang of it.
Chemicals: needed: 1. Cadmium Sulphide = cds 2. Cadmium Chloride == cdcl 2 ( These can be in powder form ) 3. Propylene Glycol = pg this is used to mix the powders into a pasty but screen printable liquid ink type. 4. Carbon powder, if you can not find it make some yourself out of burnt wood etc... 5. Cadmium = cd 6. Tellurium = Te
Copper Chorline Solar Cell
There are many different ways to construct these home made cells, the above drawing shows a wire screen mesh that you can buy at any hardware store. Using wire mesh makes a much more powerful cell, than just using one strand of wire. before assembly, attach the wire mesh to the red copper side. use a small weight in the center of the wire mesh and using clear silicon, glue down the edges, ( make sure you don't get any glue in the area where the plastic cap is going to sit. ) now let that sit over night, then glue on your clear plastic cap on to the red copper side of cell.
these also make a great science fair project as well as providing free electricity to your home. It's going to take some practice if you do any of these projects.
Knowledge is Power! Study this Patent well and read all
you can from the free info on the internet as well about
screen printing solar cells and the many different chemicals
that can be used! The Japan Solar Cells are better to make
and will last a long time!
save our earth and let's develop solar system,solar panels,solar energy,solar power,outdoor solar lights,solar pool heaters
solar pool covers,solar electric power systems,first solar,solar eclipse,for long life human future.
