Line Plot from Scientific Research

The recombination current density as a function of the external voltage was calculated from the PL(V) data using Equation (2)[12](open circles) with an ideality factor of 1.2 for C60, 1.33 for PCBM, and 1.36 for CMC, or from the lightJV-curve that was measured using the PL(V) setup and the maximum possible photocurrent for each device (solid lines) such thatJrec=Jlight+Jph,max. A zoom in the region of SC and low forward bias is shown;Jrecat SC fit perfectly from both the PL(V) and the upshift of the lightJV-curve byJscfor the three devices.
