Solar powered electric vehicle DC motor drive

The solar cells are made of semiconductor material with a p-n junction fabricated in a thin wafer layer. These cells, when exposed to light, aphoto current proportional to the solar radiation is generated. In the dark, the I-V characteristics of a solar cell have an exponential characteristic similar to that of a diode . In order to maximize the output power from a PV cell with the help of MPPT control, the modeling of PV cell is necessary. The ideal equivalent circuit of a PV cell is a current source in parallel with a single-diode.
