This introduces you to the actual curve shape and its 5 key points, including Voc and Isc. You also learn how a solar cell (or module) is a 'passive' electronic device - it does not set the voltage or current in a circuit, those values are determined by the interaction of the cell or module with the load that it is connected to. The IV Curve is a 'curve of possibilities', and it shows you where it can operate, and where it cannot.
