(a) Wet layer thickness (𝑡_WET) as a function of the spiro-MeOTAD concentration, fitted with an exponential. (b) Short circuit currents (squares) and fill factors (circles) for ssDSCs as a function of spiro-MeOTAD overlayer thicknesses, for spiro-MeOTAD concentrations of 100 mg mL⁻¹ (open symbols) and of 200 mg mL⁻¹ (closed symbols).
