Explanation for the dark I-V curve of III-V concentrator solar cells
The dark behaviour of a solar cell has traditionally been modelled by means of an equivalent circuit consisting of a lumped series resistance (Rs), a lumped shunt resistance (RP) and a diode with an ideality factor ranging from 1 to 2. In most cases, the experimental data for III-V solar cells cannot be fitted properly using just one diode.
