PHOTOVOLTAIC JUNCTION FOR A SOLAR CELL |
摘要 |
A photovoltaic junction for a solar cell is provided. The photovoltaic junction has an intrinsic region comprising a multiple quantum well stack formed from a series of quantum wells separated by barriers, in which the tensile stress in some of the quantum wells is partly or completely balanced by compressive stress in the others of the quantum wells. The overall elastostatic equilibrium of the multiple quantum well stack may be ensured by engineering the structural and optical properties of the quantum wells only, with the barriers having the same lattice constant as the materials used in the oppositely doped semiconductor regions of the junction, or equivalently as the actual lattice size of the junction or intrinsic region, or the bulk or effective lattice size of the substrate. Alternatively, the barriers may contribute to the stress balance. |
