Can someone tell me what's wrong with my photovoltaic cell fill factor?

  1. Dec 9, 2011 #1
    1. The problem statement, all variables and given/known data
    A 12V photovoltaic cell receives solar irradiance of 200W/cm^2. Measurement show that the photovoltaic cell has an open-circuit of 0.6V, short-circuit current of 3A, and the photovoltaic cell maximum current is 80% of the short-circuit current. The efficiency of the photovoltaic cell is 10%. Calculate the photovoltaic cell maximum voltage and the photovoltaic fill factor.

    2. Relevant equations
    n = Pmp/Pin , FF = (Vmp*Imp) / (Voc* Isc)

    3. The attempt at a solution
    I calculated my Vmp = 8.33V , FF = 11.11 (Which is wrong!!) Because it's more than 1! Can someone tell me where i got it wrong? Or is the the value of the question was wrong? Because i sort of added some of these value myself to simulate my coming test..

    I've also attached a pdf file asking another question on b) At 400W/m^2 solar irradiance and 25 degree, estimate the following, open-circuit voltage and short-circuit?

    Thanks for replying!
