Short-circuit current density jsc as a function of effective absorbance = αeffd. The short-circuit current density of the cells was measured under standard AM1.5 illumination (ex-situ). The effective absorption coefficient was determined using exponential fits of the transient transmission signal at a wavelength of 656 nm (in-situ). The final thickness d of the solar cells was measured after deposition using a surface profiler (Dektak).
