How can we explain the shift of photocurrent potential onset in negative direction with increase of number of CdS SILAR deposition cycles on ZnO mesoporous anode? What to-date nanostructured semiconductors' band theory is appropriate in this case?

Please, first you can reading Wiley VHC , Riidiger Memming by titelSemiconductor Electrochemistry. Its very clear.

Does anyone have reference data for Hexagonal CdS optical adsorption bandgap?

Bulk cubic CdS is known to have band gap of 2.42 eV. But hexagonal CdS band gap is not so easy case to find. Does anyone have reference data for bulk hexagonal CdS bandgap?
