摘要

Despite the remarkable advantages of luminescent solar concentrators (LSCs),their application has not been of interest in ultrahigh efficient photovoltaicmodules such as multi-junctions and related two-terminal tandems due tochallenging issues limiting the cell capability and impeding the output current.Here type of multi-junction LSC photovoltaics is presented that consistsof transfer-printed arrays of InGaP/GaAs solar cells and strategically tailoredluminescent waveguides. A coplanar waveguide with the non-self-alignedquantum dot luminophores enables simultaneous absorptions of the directlyilluminated solar flux and the indirectly waveguided LSC flux, where celldeployment and luminophore spectrum are systematically tuned for balancedenhancement of the subcell photocurrents. Through systematic comparisonsacross various LSC configurations supported by both experimental and theoreticalquantifications, the power conversion efficiency of flexible modules withInGaP/GaAs cell arrays is improved from 1.67% to 2.22% by the optimal LSC,where the module area is 14.4 times larger than the total cell area. The detailsof optical and mechanical studies provide a further comprehensive understandingof the suggested approach toward multi-junction LSC photovoltaics.
