“…18,19 As illustrated in the schematic energy band diagram of Fig. 4A, the p-i-n type of a-Si has a band structure similar to that of the p-type, 49 indicating that it can function as a photo-generated electron supplier for the solar-driven electrochemical reduction of protons. Electrons from excitons created by light absorption migrate to the semiconductor/electrolyte interface following an electric field across the MIS junction, and transfer through SiO x to the Ni-Mo catalysts where faradaic reduction takes place.…”

“…Furthermore, an impressively high MPP of 1457 mV versus RHE is exhibited by the platinized photocathode, with a photocurrent density of 4.4 mA/cm 2 , which accentuates both, the excellent catalytic activity of platinum as a catalyst for the hydrogen evolution reaction (HER) and its viable combination with the a-Si:H/a-Si:H/ZnO/Ag tandem device. In fact, the photocurrent density of 4.4 mA/cm 2 at 1457 mV versus RHE is the highest reported value at such positive potentials for a-Si:H single and tandem solar cell based photoelectrodes [13,[41][42][43]. Photocathodes, which can provide high photocurrents at more positive potentials, could effectively attenuate the catalytic activity requirement (i.e., reduction of overpotential losses) of the anode in a twoelectrode PEC system.…”

“…Taking additionally into account the nonideal illumination of the a-Si:H/a-Si:H photocathode by the halogen lamp, our result a fortiori demonstrates the capability for a direct application of the developed photocathodes in efficient and self-contained PEC devices. A prior study on amorphous tandem junction solar cell used as photocathode reported onset values of 1.35 V versus the saturated calomel electrode (SCE) along with a photocurrent density of 2 mA/cm 2 at 0 V versus SCE [41]. A similar approach led to 1.43 V versus SCE and 3 mA/cm 2 at 0 V versus SCE [42].…”

Hydrogenated amorphous silicon thin film tandem solar cells (a-Si:H/a-Si:H) have been developed with focus on high open-circuit voltages for the direct application as photocathodes in photoelectrochemical water splitting devices. By temperature variation during deposition of the intrinsic a-Si:H absorber layers the band gap energy of a-Si:H absorber layers, correlating with the hydrogen content of the material, can be adjusted and combined in a way that a-Si:H/a-Si:H tandem solar cells provide open-circuit voltages up to 1.87 V. The applicability of the tandem solar cells as photocathodes was investigated in a photoelectrochemical cell (PEC) measurement set-up. With platinum as a catalyst, the a-Si:H/a-Si:H based photocathodes exhibit a high photocurrent onset potential of 1.76 V versus the reversible hydrogen electrode (RHE) and a photocurrent of 5.3 mA/cm2at 0 V versus RHE (under halogen lamp illumination). Our results provide evidence that a direct application of thin film silicon based photocathodes fulfills the main thermodynamic requirements to generate hydrogen. Furthermore, the presented approach may provide an efficient and low-cost route to solar hydrogen production.

Hydrogen production in cyanobacteria is particularly attractive because t11ese organisms are able to generate their own source of organic substrates using light energy and use water as their ultimate source of reductant. Molecular biology approaches are being applied to understanding and increasing hydrogen production in filamentous strains of cyanobacteria. The soluble hydrogenase structural genes of Anabaena PCC 7120 were not identified by hybridization experiments. Characterization of an Anabaena PCC 7120 DNA fragment identified by hybridization analysis using the soluble hydrogenase gene from Anabaena cy/indrica as a heterologous probe resulted in the identification of the genes for a putative restriction-modification enzyme system of Anabaena PCC 7120. Experiments have continued towards the development of a genetic system for Spiru/ina pacifica. These include (l) the identification of three unique restriction enzymes and (2) PCR amplification of the gene encoding the 16S ribosomal RNA in this strain.
