The Fill Factor of the Silicon Photocell

  1. Mar 10, 2009 #1
    1. The problem statement, all variables and given/known data
    I have to find the value of the Fill Factor of the silicon photocell.
    I graph for current, voltage and power.

    I got this as a value 1.6x10-2

    Is this the correct answer ?
    I just need the real value so I can compare it with my results ..

    2. Relevant equations


    3. The attempt at a solution

    Pmax/Po = (9.5x〖10〗^3µW)/(5.7x〖10〗^5µW) = 1.6x10-2

    I have to submit the lab report tomorrow .. Please help me =[

    The fill factor is "ratio of photodetector area to total area of the circuitry".
    You have given no information on these areas, so no answer can be computed.

    Umm ... I followed what the lab manual told me ...

    " Calculate the fill factor, defined as the ratio Pmax/Po. Find the position of the point where the power is maximum on the i-V characteristic and draw a line to it from the origin. This is called a load line. "
