摘要： A metamorphic avalanche photodetector includes a substrate, and an active structure supported on the substrate. The active structure has a metamorphic absorption structure that absorbs light and responsively produces primary charge carriers, and an avalanche multiplication structure that receives the primary charge carriers from the metamorphic absorption structure and responsively produces secondary charge carriers. An output electrical contact is in electrical communication with the active structure to collect at least some of the secondary charge carriers. A buffer layer lies between the substrate and the active structure, between the active structure and the output electrical contact, or between the metamorphic absorption structure and the avalanche multiplication structure. A lattice parameter of the buffer layer varies with position through a thickness of the buffer layer.

摘要： A solar cell includes a first layer having a first-layer lattice parameter, a second layer having a second-layer lattice parameter different from the first-layer lattice parameter, wherein the second layer includes a photoactive second-layer material; and a third layer having a third-layer lattice parameter different from the second-layer lattice parameter, wherein the third layer includes a photoactive third-layer material. A transparent buffer layer extends between and contacts the second layer and the third layer and has a buffer-layer lattice parameter that varies with increasing distance from the second layer toward the third layer, so as to lattice match to the second layer and to the third layer. There may be additional subcell layers and buffer layers in the solar cell.

The substrate may be a second photoactive subcell layer having a second-subcell lattice parameter different from the first-subcell lattice parameter and sensitive to a second-photoactive-subcell-layer wavelength, and the buffer layer is transparent to the second-photoactive-subcell-layer wavelength.
