Combination of PL fit and PLE. The dashed lines at high energies represent the curves obtained by PLE. The cross markers associated with them correspond to the spectral width of the excitation laser and provide an idea of the horizontal error bars induced by it. Additional ±2% vertical error bars correspond to the measurement uncertainty from the incident fluence measurement. PL fit is the solid lines and allows for the estimation of absorptivity below 1.7 eV. The scales are adjusted so that the relative absorption averaged on the different areas matches the averaged squared PLE at 1.63 eV. The sky-blue line displays the squared absorptivity obtained from the reference transmission and reflection measurement.
