Ultrafast narrowband exciton routing within layered perovskite nanoplatelets enables low-loss luminescent solar concentrators

Luminescent solar concentrators are promising for semi-transparent, building-integrated photovoltaic systems. Here the authors minimize the absorption losses by relying on fast energy transfer in multiphase perovskite nanoplatelets to achieve optical quantum efficiency of 26% on 100 cm2 devices.
