How to make screen for photovoltaic cell

Scientists in Arizona are using screen-printing, a technique developed for printing fabrics, paper and to produce plastic, glass and metal solar cells.
The basic materials of a photovoltaic cell (solar cell) are inexpensive. The organic manufactured by Ghassan Jabbour and colleagues at the University of Arizona in Tucson have about 11/4 of the efficiency of commercial silicon solar cells, which turn 10-20 per cent of light energy into electricity. But, being cheap to produce, they can make up the loss in quantity what they lack in quality. Now the Japan screen printed solar cells are even better than that!

A Screen printing press, the wood frame is the screen
In conventional Screen - printing, a taut piece of screen mesh fabric is stretched over a wood frame,
you can buy the screens already made and the materials from any screen printing shop or screen printing supply company in your area or on the internet. Also you might want to check with your local art store, sometimes they have full kits etc...
The screen is then masked off using masking tape,
For example: a 5" x 5" square area. the screen outside of the masking tape is then coated with a block out
liquid or paint, this is so when you apply your semiconducting ink that you mixe, it will go through just the area that you masked off when you apply a rubber squeegee to it. The screen can then be placed on any table top and hinges attached to the back of the wood frame and the table, this will insure the screen can move up and down. Then get a small wood paint stick and using a small nail, hammer one end to the front side of wood frame. This will be your kick leg and will help keep your screen in an upward position when needed. Take a 5" x 5" piece of glass and place it right under the open 5" x 5" area of the open screen mesh. When the leg is flipped back the screen comes down and you grab your rubber and wood handled squeegee and with the ink in front of your rubber squeegee pull toward you applying pressure so ink will go through screen, once you have passed by the 5" x 5" area then flip the screen back up and reverse squeegee to flood the screen for the next print.
