• W2000779721 abstract "An approach to circumvent the problem of poor photoelectrochemical (PEC) stability of Si in aqueous electrolytes is the use of heterojunction photoelectrodes comprising the Si/SiO/sub x// indium tin oxide (ITO) structure. As in a Schottky barrier electrode system, the maximum photovoltage attainable with these electrodes is limited by the barrier height at the Si/ITO heterojunction. Both n- and p-Si substrates have been studied. In regenerative PEC systems designed for the conversion of solar energy to electricity, the efficacy of charge transfer at the ITO/electrolyte interface is shown to be a crucial factor. Of the redox electrolytes tested (S/sup 2 -//S/sup 2 -//sub x/,, I/sup 3 -//I/sup -/, (Fe(CN)/sub 6/)/sup 3-/4-/ and Fe/sup 2+/3+/ EDTA), the (Fe(CN)/sup 6//sup 3-/4-/ couple was by far the most efficient in terms of charge transfer across the ITO/electrolyte interface. Optical-to-electrical conversion efficiencies (eta) of 1.57% and 5.7% (approx. AM 1 illumination) were attained for PEC cells based on n- and p-Si substrates, respectively. Detailed tests have revealed long-term stability in (Fe(CN)/sub 6/)/sup 3-/4-/ electrolytes once the ITO film thickness (greater than or equal to 50 A) and solution pH (approx. 12 to 14) were optimized, n-Si/ITO electrodes were used for the photooxidation of Cl/sup -/more » from concentrated LiCl and NaCl electrolytes to illustrate the chemical inertness and stability of these electrodes. Catalytic modification of the ITO surface with RuO/sub 2/ was found to be necessary to sustain Cl/sub 2/ production. Values of eta up to 2.7% were recorded with this PEC system at 100 mW/cm/sup 2/. Finally, the applicability of Si/ITO heterojunction electrodes for the photoassisted splitting of water was demonstrated. Preliminary experiments have revealed a 40% reduction in the threshold voltage required for water photolysis. Catalytic modification of the ITO surface was again a prerequisite for efficient performance of these electrodes.« less" @default.
