Photowatt chooses Dupont’s Solamet™ materials for its PV solar cells

For many years, Photowatt has been a European leader in the manufacture of photovoltaic (PV) solar cells. Since 1997, the company, based at Bourgoin-Jallieu, near Lyon, France, has been a part of ATS (Automation Tooling Systems), a large multinational concern with its headquarters in Toronto, Canada. ATS specializes in the fabrication of automated production lines for the automotive and electronics industries.

Подпись:In 2001, the PV market grew by 39 per cent, based on power in megawatts (MWp), and Photowatt is well positioned to take advantage of this buoyant market. Like most large PV manufacturers, the company has increased capacity every year to cope with demand and, between 1995 and 2002, its production capacity has increased 10-fold, from 2 to 20 MW.

Photowatt has an advantage in the indust...

Screen Printing

Learn how to Screen Print. Screen printing is done all over the world by very large printing companies right down to the guy who does it at home in his basement. Screen printing was first discovered by the Chinese hundreds of years ago. It is a very simple process that anyone can do. The Chinese first used silk to use in there wood frames to print with, then as time went on better material was made to print with

Applying The Solution

image028Temperature and variations in the chemical mixture can dramatically change the time required to complete the silvering process. The best way to complete this step is by simple visual examination of the process as it proceeds.


With the cell on a flat surface, begin by carefully pouring the silvering mixture on to the center of the cell. Remember to avoid letting this mixture contact any exposed copper. A good trick is

to cover with paint or lacquer any exposed copper surfaces on the face of the cell. Continue pouring until the liquid has covered as much of the surface as you can. I f all the exposed copper on the surface has

been properly protected with the lacquer, you can actually pour the solution until it comes right to the edge...

Begin by carefully polishing the face of the cell with a fine grade of steel wool until it shines brightly. Then place the cell with the shiny side up, in the solution of nitric acid.

Soon, tiny bubbles will form on the copper disk. Stir the solution occasionally. When the disk seems shiny and well cleaned, remove and rinse it under cool running water.

WARNING! Never to allow your skin to touch the acid, and that no acid remains on the cell.

The cell will sometimes work without the acid cleaning if it is simply well polished by the steel wool. However, we strongly recommend the acid cleaning.

Nitric acid and the other chemicals mentioned in the text can be easily ordered from a number of mail-order chemical houses such as found in the classified section of magazines such as Popular Science...

Building your solar Cell

Step 1. Cut a piece sheet copper into the size and shape you wish for your cell. Although.025 inch thick copper was used for the cells described here, just about any thickness will do.

Copper is a soft metal and can be cut with tin snips or even with an old pair of scissors.

Cut your cell with a diameter of 1 1/2 inches, we strart with a smaller cell because it is much easier to work with. The larger the heat source the bigger the size copper you can use to create your solar cell. After you get the hang of it you can then build larger cells..

As you cut the copper, be sure to leave a "handle" so that you may grip the cell with pliers without marring the cell’s active surface.

An Experimental Cell With Cuprous Oxide

The best cell by far for the you to start with, is a cell made with cuprous oxide (CuAO). Copper actually has two oxides, a red oxide called cuprous oxide, and a black oxide called cupric oxide (CuO).

The dark red cuprous oxide has photoelectric properties but black cupric oxide does not. The black oxide that forms on the outside of your cell must be removed because it is opaque and will not allow light to reach the cell’s active surface.

Homemade Copper Solar Cells

Selenium was extensively used in the production of commer­cial solar cells before silicon. Although it can be a somewhat difficult to find a supplier and it is a toxic heavy metal, it is relatively inexpensive and can often be found in old model radio sets, where it was used in the rectifier of the power supply.

A selenium photocell is made from a metal plate (usually iron) with one side being covered with a l ayer of selenium. A very thin layer of silver or gold is spattered over the selenium layer forming a layer of current-carrying material that allows light to pass through it. This layer is called a transparent electrode. A metal electrode called a collector, rests on the gold or silver near the edge of it.

Wires are attached to the collector and the iron plate to deliver the electric...
