| 英文摘要 | The photovoltaic conversion efficiency for monolithic gainp/gainas/ge triple-junction cell with various bandgap combination (300 suns, am1.5d) was theoretically calculated. an impressive improvement on conversion efficiency was observed for a bandgap combination of 1.708, 1.194, and 0.67 ev. a theoretical investigation was carried out on the effect of dislocation on the metamorphic structure's efficiency by regarding dislocation as minority-carrier recombination center. the results showed that only when dislocation density was less than 1.6x10(6) cm(-2), can this metamorphic combination exhibit its efficiency advantage over the fully-matched combination. in addition, we also briefly evaluated the lattice misfit dependence of the dislocation density for a group of metamorphic triple-junction system, and used it as guidance for the choice of the proper cell structure. |
