Record 29% Concentrating Solar Cell Aims At Low-Cost Manufacturing

A novel combination of high-grade spacecraft solar cell material and advanced light-concentrating lenses has yielded solar panels with a record 29% efficiency that may become available for general rooftop use by 2022. The crux in the commercialization of the planar optical micro-tracking technology will be cost-controlling manufacturing process, which is the current stage of study for Insolight, the cell developer.
