Modification of several semiconductors material surfaces with H4SiW12O40•nH2O have been carried out to produce an increase in the open circuit photopotential at the semiconductor/electrolyte interface (Voc) without changing the flat-band potential. The augmentation of Voc is shown to be attributed to a decrease of the minority carriers recombination at the semiconductor/electrolyte interface along with the suppression of Fermi level pinning. The enhancement of Voc and the electrocatalytic activity of the hydrogen evolution reaction in acidic medium of the derivatized electrodes is attributed to the Fermi level unpinning. Keywords: photoelectrodes, photoelectrocatalysis, pinning, modification improvement.

The sum of ionization energy and electron affinity for aromatic hydrocarbon molecules is constant and therefore the Fermi level for intrinsic aromatic hydrocarbon crystals is in first approximation independent of the nature of the hydrocarbon. This relationship leads in turn to a constant value for the flat band potential of aromatic hydrocarbon crystals in contact with an electrolyte. An estimate of this value is given.
