Photoinduced change in quasi-Fermi energy \({E}_{{{{{{{{\rm{f}}}}}}}}}^{{{{{{{{\rm{q}}}}}}}}}\) (a, b) and bandgap ΔEg (c, d). ΔEg is defined as the energy difference of bandgap Eg between after- and before- photoexcitation. All ΔEg are found to be positive. Errors of the parameters are standard error that is determined by calculating the 95% confidence interval, based on residual values and Jacobian matrix obtained from the fits to Eq. (7).
