For III-V solar cell manufacturers, it is Earth rather than space that represents the final frontier. However, recent advances in the performance of cells and high-concentration optical modules suggest that multi-junction photovoltaics can infiltrate the silicon-dominated terrestrial energy market. Michael Hatcher reports on the latest developments.
