Figure 4: Active layer thickness-dependent variation of photovoltaic performances.
From: A molecular nematic liquid crystalline material for high-performance organic photovoltaics

(a) Plots of Jsc or Voc vs active layer thickness ranging from 80 to 400 nm. (b) Plots of FF or PCE against active layer thickness. The results are an average value of >8 devices. The error bars represent the standard deviation from >8 devices.
