LATTICE MATCHABLE ALLOY FOR SOLAR CELLS |
| 摘要 |
An alloy composition for a subcell of a solar cell is provided that has a bandgap of at least 0.9 eV, namely, Ga1-xInxNyAs1-y-zSbz with a low antimony (Sb) content and with enhanced indium (In) content and enhanced nitrogen (N) content, achieving substantial lattice matching to GaAs and Ge substrates and providing both high short circuit currents and high open circuit voltages in GaInNAsSb subcells for multijunction solar cells. The composition ranges for Ga1-xInxNyAs1-y-zSbz are 0.07≧x≧0.18, 0.025≧y≧0.04 and 0.001≧z≧0.03. |

1. A multijunction solar cell comprising:
a first subcell comprising Ga1-xInxNyAs1-y-zSbz , wherein, the content values for x, y, and z are within composition ranges as follows: 0.07≧x≧0.18, 0.025≧y≧0.04 and 0.001≧z≧0.03; and at least one second subcell overlying the first subcell to form the multijunction solar cell. |
