Solar cell open circuit voltage and bandgap

  1. Mar 28, 2013 #1
    Hello Forum,

    if we take a silicon solar cell, the open circuit voltage is about 0.5V.

    the current increases as the solar cell area and illumination increases.

    But the 0.5 V output voltage does not change as the area and illumination level vary....Why?

    It must have something to do with the bandgap...

    The open circuit voltage is characteristics of solar cell (specically for P-n junction solar cell) which depend only on the material parameters.
