Amorphous silicon carbide photoelectrode for hydrogen production directly from water using sunlight

Gradient dopant profiling and spectral utilization of monolithic thin-film silicon photoelectrochemical tandem devices for solar water splitting

“…Although the potential of À1 V vs. RHE is of little relevance, this photocurrent is 100% higher than that of any other reported a-SiC:H photocathodes. 26 …”

“…20,21,[23][24][25][26][27] In 2007, Zhu et al demonstrated a simple p/i a-SiC:H photocathode that was free of its native oxide and generated a photocurrent density of $À0.6 mA cm À2 at 0 V versus the reversible hydrogen electrode (vs. RHE). 20 Only at a negative bias of À1.5 V vs. RHE did the photocurrent density reach $À7 mA cm À2 , showing the large overpotential needed to drive the a-SiC:H photocathode to higher photocurrent densities.…”

Experimental demonstrations of spontaneous, solar-driven photoelectrochemical water splitting

“…49,62,84 Only a few SLJ devices have reported stabilities of 41 day. 87 Additional information regarding longevity is provided in the ESI. † Long term stability presents considerable challenges for the materials in contact with the electrolyte.…”

Cold Plasma – A Promising Tool for the Development of Electrochemical Cells

“…No wonder that a broad search for new materials for photoelectrodes is still ongoing. Cold plasma technology is also involved in this activity (Randeniya et al, 2007;Slavcheva et al, 2007;Walsh et al, 2009;Zhu, F. et al, 2009).…”
