114 Experiment 19 I-V Characteristic of Solar Cell Apparatus : Solar cell, rheostat, ammeter, voltmeter, illumination source, varic and connecting wires. Purpose of experiment: To study illuminated characteristics of a solar cell for different illumination levels. Basic methodology: A solar cell is illuminated by light having photon energy greater than the band gap energy of the solar cell. Then, using a proper circuit, the open circuit voltage, short circuit current and power drawn from the solar cell are measured. I. Introduction I.1 Solar cell is basically a two terminal p-n junction device designed to absorb photon absorption through the electrical signal or power in the external circuits. Therefore it is necessary to discuss the physics of semiconductor p-n junction diode, which
