Figure 2: Photoconductivity and ideality factor.

From: Impact of charge transport on current–voltage characteristics and power-conversion efficiency of organic solar cells

Figure 2

(a) Relative extraction rate of the photogenerated current as a function of the external voltage for six different mobilities at an illumination intensity of ‘1 sun’. (b) Corresponding effective average conductivity (see text) at Vext=0 as a function of mobility under illumination and in the dark. (c) Ideality factor nid as a function of light intensity for six different mobilities. (d) Apparent shunt resistance Rp as the function of light intensity as determined from the inverse slope of the simulated Jillu(V) at V=0. The case of μ=1 cm2(Vs)−1 was left out for better visualization.
