Japan methode to make a home made solar cell

The 1996 japan Patent is by far the best and the most powerful. The japan patent uses a simple process that has been used for centuries, You simply screen print the negative and positive layers and the contact layers on to a piece of glass plate, it does not matter how thick the glass is. The layers can be sprayed on with a spray gun and a air compressor, but it is best to Screen print it. Screen printing each layer will make your solar cells last longer and they will be more efficient
If you do not know what screen printing is, you can learn about this very simple process from the Library. Also lots of info and supplies can be purchased at your local hobby store or art supply store. You can also buy supply's such as screens and such at a local Screen printing shop. or they can screen print it for you. Screen printing is very simple and cheap to do for you self right in your own home. It may take a little studying but it will be worth it. you can print up as many Solar Cells as you want for just pennies. ( Cover your entire roof with them. You will have more energy than you will ever need. You can then make money selling electricity back to the electric company which should pay for it self in one to two years. The most expensive part is the deep cycle marine batteries and your inverters. Many are making a nice income every year from this, just by selling electricity back to the electric company, ask to see if your electric company has that type of program in your area. most states I heard do.
The Japan method is new and it is not limited to just a glass surface, you can also apply it right onto aluminum or copper sheeting. Look at the 1 st page, see the N type layer #2 this is what the Patent says to Print first. But if you want to print onto a metal surface the metal surface would be #5 then the 1 st print would be #4 then let it air dry and then bake at 600 degrees for 3 to 5 minutes.
(Each printed layer can be done this way.) Then your 2nd print would be #3, then you let air dry, then bake, then Print #2 Air dry/bake. Then you must print a Metal grid over #2 then let air dry, (you don't have to bake the metal print. ) This will be your negative contact, #5 will be your Positive Contact, so what your doing is just simply reversing the printing layer steps. If you have never seen a solar cell the metal grid is like a metal door screen but with bigger spacing. You can buy a special metal printing ink or mix it your self as the patent says. The ink is simply made up of nickel or silver. Nickel is the cheapest and will work just fine.
