grapa.datatypes.curveEQE.bandgap_tauc

grapa.datatypes.curveEQE.bandgap_tauc(nm, eqe, ylim=None, xlim=None, mode='EQE')

Performs fit of low-energy side of EQE and returns [bandgap, slope]. Executed at initialization of CurveEQE.

Parameters:

• nm – x series

• eqe – y series

• ylim – by default, [0.25, 0.70]

• xlim – by default, [600, 1500]

• mode – ‘EQE’, or ‘ln1-EQE’
