Trying to understand JV Performance graphs

  1. Sep 17, 2014 #1
    Hello PF,

    New to PF, first post! I graduated with a BS in Chemistry in 2010, and I have started my graduate studies in Materials Science. My physics/electrical engineering knowledge is a little shaky, and I am trying to catch up.

    During group meetings, a lot of graduate students are presenting JV Performance graphs and I'm having a tough time wrapping my head around the concept of a JV Performance graph.

    From information I've gathered: J = electric current density and V = voltage. J is on the y-axis and V is on the x-axis of the graphs. Most of the graphs so far have a curve that looks similar to a natural log curve.

    If you were teaching an Intro to Physics class about JV performance graphs, how would you explain the concept to the students?
