Solar Cells

Efficiency of a solar cell is given in terms of maximum power that solar cell can generate for a given input solar radiation. The maximum power output (Pmax or Pout) of solar cells depends on voltage developed across cell terminal and current it can supply. The cell area also affects the power output.
