“…Dimroth et al used 10 periods of AlInAs/GaInAs bilayers in GaInP/GaInAs tandem cells to enhance optical absorption [11,12]. Shvarts et al employed a 12-period AlAs/GaAs DBR as a selective mirror in the base of AlGaAs/GaAs solar cells for space applications, demonstrating improved quantum efficiency as well as radiation stability [13][14][15][16]. DBRs were used to enhance radiation stability and improve efficiency of monolithic multijunction solar cells by Azur Space [17].…”

“…Notably, such filters can be feasibly built into the rear of a solar cell using current industrial facilities. There have already been works reporting on the use of distributed Bragg mirrors to enhance light reabsorption in monolithic multijunction cells. The method can be adapted, such as by tuning the optical windows, to find its new applications in next‐generation spectrum‐splitting photovoltaics.…”

Increasing the sunlight to electricity conversion efficiency is a key driver for on‐going photovoltaic cost reduction. One of the most successful approaches for improving the efficiency is to split sunlight into suitable spectral bands for a set of solar cells with appropriate energy band gaps. Using this concept, in 2014, our group demonstrated the first photovoltaic conversion efficiency above 40%, where an external filter directed a portion of the sunlight normally wasted by commercial InGaP/InGaAs/Ge triple‐junction cells to a silicon cell. Here, we analyze the primary power losses in state‐of‐the‐art spectrum‐splitting photovoltaic modules and evaluate the potential for further efficiency increase. Two further developments, applying built‐in filters and generalizing the present concept, are proposed for next‐generation spectrum‐splitting photovoltaics, which can make 50% efficiency a realistic target. The design principal is briefed as is the comparison with monolithic multijunction cells.
