Summary: The lattice-matched III-N-V/Si double-junction solar cells with GaNAsP and GaInNP top cells were designed and their efficiencies were calculated by varying the electron lifetime and electron surface recombination velocity in the top cell. The optimal efficiency of the GaNAsP/Si cell increased from 31.12% to 36.13% with the increase in electron lifetime, while the effect of electron surface recombination velocity was negligible. The optimal efficiency of the GaNAsP/Si cell was less sensitive to electron surface recombination velocity compared to electron lifetime. Moreover, the optimal efficiency of the GaNAsP/Si cell slightly decreased with thinner Si substrate but had a maximum with a specific doping concentration.

Summary: This study conducted a first assessment of SiGeSn deposition in an MOVPE chamber used for III-V growth, with the aim of improving control over SiGeSn composition and epitaxial layer morphology. The research revealed that the gas source Si2H6 is more sensitive to growth temperature compared to GeH4 and SnCl4, and that SiGeSn morphology depends strongly on temperature, As carry-over, and growth rate. Additionally, a new growth model was introduced to explain how adatom bond lengths inhibit tin segregation in SiGeSn grown at high temperatures. An experimental device combining GaAs/InGaP/SiGeSn/Ge was fabricated and characterized, demonstrating SiGeSn's higher absorption coefficient compared to Ge.
