Figure 10. The temperature dependence of the ideality factor, n: Open triangles stand for values obtained after the slope of ln J curves when we neglecting the series resistance Rs and open stars represent n as fitting parameter of I-V curves with Eq. (7) when neglecting the presence of Rs. where Rs0 and α are constants: R_s0 = 21.18 Ω and α = 3.85 x 10^-3K^-1. This decaying behavior indicates that Rs has some semiconducting properties.
