PHOTOVOLTAIC DEVICE

摘要

A multijunction photovoltaic device (300) is provided. The multijunction photovoltaic device (300) includes a substrate (301) and one or more intermediate sub-cells (303a-303c) coupled to the substrate (301). The multijunction photovoltaic device (300) further includes a top sub-cell (304) comprising an AlxIn1-xP alloy coupled to the one or more intermediate sub-cells (303a-303c) and lattice mismatched to the substrate (301).
