The maximum power point (P max) is the product of the maximum cell current (I max) and the voltage (V max) where the power output of the cell is greatest. A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. Offered by Technical University of Denmark (DTU). Illuminating a cell adds to the normal "dark" currents in the diode so that the diode law becomes: The filling factor (FF) is defined to be P m / (I sc.V oc), which represents an important parameter used to evaluate the quality of the solar cell.. P m is the maximum output power of the solar cell, i.e., the maximum value of I * V.. Short-circuit current (I sc) is the output current of the solar cell when the external circuit is shorted, i.e., zero load resistance. For small.
