3.2VDC/80MA CIS SOLAR CELLS
SOLAR CELL, 60MM X 60MM X2MM
These are thin-film Copper Indium Diselenide (CIS) solar cells. Recent production, first quality, made by a major solar manufacturer. 60mm x 60mm x 2mm thick (2.4" x 2.4" x .08") The active semiconductor material is deposited on the front of the glass, tinned ribbons are bonded to the edges, then the whole cell is covered with clear tough plastic to protect the cell and ribbon. They are environmentally protected and ready to use. You just solder to the ribbon and mount them in your project. The cells put out about 4.5VDC open circuit and about 100MA short circuit. Maximum power of the ones tested is about .25 watt (80MA at 3.2VDC). 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 often used in spacecraft applications. You can connect them in series for more voltage and in parallel for more current. These should be good for walkway lights, battery charging, remote instrumentation or data loggers, educational projects and other DC electrical applications. Unlike amorphous silicon panels, CIS panels do not degrade due to sunlight exposure. In fact after at least 2 hours of exposure to sunlight of at least 1/2 standard intensity, the output will increase by about 10%. With the first exposure, the semiconductor material is annealed and the output is then stable at the higher level. (This is called light soaking). We have a very large quantity for immediate sale. Large quantity orders invited. Subject to prior sale. Special prices for exporters, resellers and large quantity users.

ELECTRONICS INSTRUCTORS
AM RADIO KITS OFFERS YOUR STUDENTS REAL HAND'S ON EXPERIENCE - TRANSISTOR CIRCUIT SHOWS HOW RADIOS REALLY WORK!
RADIO KITS
What better way to get students interested in the world of electronics… this AM radio kit offers a world of education plus hands-on experience, with a fine AM Radio as the finished product. These kits were designed to allow the student to understand the theory behind radio reception, and to allow the student the thrill of building and using his/her own receiver. In this world of mass produced electronics, this kit is a welcome relief.
Features a superheterodyne receiver circuit with 2 IF stages, AVC, loop antenna, push-pull output stage, 4" wide range speaker and a cabinet that houses the finished radio. Operates on 4 "D" batteries. The circuit uses 6 transistors and since each stage is built and checked by the student before proceeding, it offers a much better grounding than any kits available today which feature full integrated circuit construction. In this older style, the student actually gains an understanding as to how each stage functions. These are almost impossible to find, but we found a few hundred of these complete, unassembled kits that were used by many school systems to guide students towards this fascinating field. As these are older kits (but brand new) they could also be thought of as collector's items… but in reality, their educational value far surpasses their nostalgic qualities. This is an educational bonanza!!!! Cabinet included.
