Scatter Plot from Scientific Research

Nyquist plots at different scales of a PM6:Y6 solar cell with different applied biases, including VOC: a) and b) in the dark, c,d) under 1 sun equivalent illumination. Most curves can be fitted across a range of frequencies to a semicircle (highlighted by grey circles in a) and b) and yellow circles in c) and d); various shades of grey and yellow correspond to different applied biases) represented by a parallel combination of an ideal resistor and an ideal capacitor.
