Solar Cells

Thin-film Copper Indium di Selenide (CIS) solar panels. These are recent production, first quality, made in the USA. $1.50each, 5000pc min order.
They are 60mm x 60mm, 2mm thick. (about 2.4" x 2.4" x .08")They have the active semiconductor material deposited on the front surface of the glass, ribbons bonded to the edges, then the whole thing is covered with clear tough plastic to protect the cell and ribbon. So they are environmentally protected and ready to use, you just solder to the ribbon and mount them in your project.
They put out 5V open circuit, and about 100mA short circuit. Max power of the ones I tested is about .25W. The spec that they were tested to in production was 1/2 sun (500W/m2 irradiance), 2.9V, 32mA minimum. So they all meet or exceed that spec. That comes to .09 watts, under half sun conditions, so it makes sense that they would be more than double under full sun. CIS is the most stable and rugged of the thin film solar technologies, and is about twice as efficient as amorphous silicon. It is more efficient under cloudy or partial shade conditions than crystalline silicon. CIS is also radiation resistant, and therefore is often used in spacecraft applications.
You can connect them in series for more voltage, and in parallel for more current.
Ought to be good for walkway lights, battery charging, remote instrumentation or data loggers, educational projects, and other dc electrical applications, etc
We have a huge quantity of these, so if you have a volume product in mind that can use them, email us.
