Extracting large photovoltages from a-SiC photocathodes with an amorphous TiO2 front surface field layer for solar hydrogen evolution1. Issue 5 (6th May 2015) - Digdaya, Ibadillah A.
Abstract A p–i–n junction photocathode made from 110 nm (p/i) amorphous SiC and an (n) TiO2 top layer leads to an onset potential of +0.8 VRHE and a photocurrent density of 8.3 mA cm−2 at 0 VRHE using only earth abundant materials.
