15.4: Diodes, LEDs and Solar Cells
Diodes are semiconductor devices that allow current to flow in only one direction. Diodes act as rectifiers in electronic circuits, and also as efficient light emitters (in LEDs) and solar cells (in photovoltaics). The basic structure of a diode is a junction between a p-type and an n-type semiconductor, called a p-n junction.

What exactly is a current source?
If you connect a 36mΩ resistor to the panel 2.75A will flow through the resistor yielding a 0.1V voltage drop on it. If you now increase the resistor to 150mΩ the current will remain constant at 2.75A and the voltage drop across the resistor will increase to ~0.4V. If you keep increasing the resistance the current will eventually drop.
