Concepts for obtaining practical solar cell modules with one-sun efficiencies up to 30% at air mass 1 are now well understood. Such high-efficiency modules would utilize multibandgap structures. To achieve module efficiencies significantly above 30%, it will be necessary to employ different concepts, such as spectral compression and broad band detection. A detailed description of the concepts for the design of high-efficiency multibandgap solar cells is given.
