“…The group V halides all have relatively low boiling or sublimation temperatures (table 4), but the temperatures for the fluorides are lower than those of the other halides. PF 3 , PF 5 , and NF 3 are especially volatile, evaporating well below room temperature. Thus, even though chlorine species may be primarily responsible for etching, fluorine atoms may contribute to the etch process, particularly in the absence of aluminum.…”

“…MJ systems are usually constituted by three different possible substrate: Ge, GaAs, and InP. The introduction of chemical components in the different layers is beneficial (Yamaguchi et al, 2005): Al in the top cell has the property of increasing E G to values that cover a larger part of the solar spectrum, while few amounts of In reduce the mismatch between layers. In the context of the Japanese "New Sunshine Project", InGaP/InGaAs/Ge monolithic integrated cells have reached an efficiency of 31.7%, while for the stacked InGaP/GaAs//InGaAs ones an efficiency of 33.3% has been reported (Yamaguchi, 2003), representing at the time of their production the efficiency World Guinness for such cells.…”

“…Also, the voltage distribution of the limiting Ge bottom cell is considered spatially uniform since the tunnel diode in between the GaAs and Ge subcells is heavily doped. 25 Hence, we assumed negligible tunneling resistance and lateral resistances. These assumptions then make the electrical circuit sufficient to expand in-plane, in 2-D.…”
