Abstract :
In summary, the direct 1D heteroepitaxy of ternary InXGa1-xAs NWs in a wide composition/bandgap range reported here enables monolithic tandem solar cells on Si substrate. Further improvement in energy conversion efficiency is expected due to the direct bandgap, enhanced light trapping, as well as bandgap and current matching by composition, doping, and height engineering.
