Other than Tauc or Kubelka - Munk.I already use Tauc's method, I just want to have a way to corroborate my data by another method.
many methods in expermental and theoretical in solid state physics
Dear Ricardo Hoffmann Valencia Sir,
The band gap of material can also be calculated using a promising cyclic voltammetry technique. the following article will help to understand the method.

Dear Ricardo Hoffmann Valencia ,
One of a simple method to determine the bandgap is the to measure the conductivity as a function of the incident light wave length. The wavelength at which the conductivity tends to zero can be considered as an approximate value corresponding to the energy gap.
Where Eg= hc/lambda cut off.
You can also excite the material and observe the wavelength of the emitted photons. The onset wavelength of the radiation can be considered that corresponding to the energy gap.
One can use the above equation to calculate Eg.
I would like that you refer to the papers:
