A small, carefully made solar cell of approximately 2 1/2" diameter will produce around 5 milliamperes of current in direct sunlight. This is enough to drive a sensitive light meter or extremely sensitive relay. Banks of these cells have even been used to run small electric motors. Experiment with the procedures described. You may stumble […]

Solar Cell Similar to the Copper Chlorine Cells. We have found that if you use Conductive Nickle Paint you will get far better results. But start out using the screen mesh or the aluminum wire. You can buy Nickle Paint on the internet. Simply search for " Nickle Paint suppliers " on your search engine. […]

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 […]

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 […]

Solar Cells convert light energy into electricity at the atomic level. It was first discovered in 1839, the process of producing electric current in a solid material with the aid of sunlight wasn’t truly under­stood for more than a hundred years. Throughout the second half of the 20th century, the science has been refined and […]

Photovoltaic (or PV, Solar Cells ) systems convert light energy into electricity. The term "photo" is from the Greek "phos" which means light. "Volt" is named from Alessandro Volta (1745-1827, He was a pioneer in the study of electricity. So you could say that" Photo-voltaics is basically light electricity! And is most commonly known as […]

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. […]
