How to make solar cell using screen printing

You can Use an outside Grill to bake the Screen Printed layers. It is a good idea to make small cells, 8" x 10" or what ever. It is easier to fit into the Grill,
We suggest Baking in side a large roasting pan and then put the roasting pan inside the preheated grill and shut the lid. It is suggested that you try and make 3 prototype cells first, Work out all the details, Test them, and then start on a large production of Solar Cells. It will all get much easier once you have done it. It is also suggested that you bake them out side. You don't want any fumes in the house, an outside grill is the best and most readily available oven there is and propane is cheap. I hear you may be able to make them without a Nitrogen atmosphere if not try special gas companies or make some yourself, it is supposed to be nonflammable.
Screen Printing: You start with a small 14" x 14" wood frame 2x2". Then a plastic or clothe screen is stretched over the frame tightly one side at a time, and then stapled down on all 4 sides, we suggest buying a yellow 200 mesh screen from a screen printing supplier, Then you put an image of what ever you want to print into the screen by photo emulsion or by cutting a lacquer or water film with an exacto knife. ( see our Screen Printing Video ) Once you have your image you place the finished screen onto a flat smooth table top, attach it to a 14" long 2" x 4" with 2 door hinges. using wood screws, then you attach the 2" x 4" on to the table so it and the screen will not move. the screen should only go up or down.
you then put your 8" x 10" glass under the screen, register it, then lay the screen down over the glass and apply your ink and then with a small 12" rubber Squeegee, You pull the ink over the image and it is pushed thru the screen mesh and thru the image that you cut and smoothly is printed onto the glass.
