Summary of Yuchen Shi's activities
My research is mainly focused on the growth of cubic silicon carbide and the characteristics of the photoelectrochemical (PEC) water splitting into hydrogen using solar energy based on 3C-SiC electrode. 3C-SiC has the lowest bandgap of 2.3eV in the polytypes of SiC, which means more sunlight can be absorbed. And it is considered to be a promising material for water splitting because of suitable band edges, high chemical stability and efficient charge transport.
But this type of PEC cells still faces serious challenges such as the recombination of carriers. So my recent work aims at making certain a detailed knowledge on the influence of the carrier lifetimes, transport properties, doping concentrations on the hydrogen conversion efficiency, and exploring a best way which give rise to the optimum conversion efficiency.
