Title: Tandem luminescent solar concentrators based on engineered quantum dots

Abstract

Luminescent solar concentrators (LSCs) can serve as large-area sunlight collectors for terrestrial and space-based photovoltaics. Due to their high emission efficiencies and readily tunable emission and absorption spectra, colloidal quantum dots have emerged as a new and promising type of LSC fluorophore. Spectral tunability of the quantum dots also facilitates the realization of stacked multilayered LSCs, where enhanced performance is obtained through spectral splitting of incident sunlight, as in multijunction photovoltaics. Here, we demonstrate a large-area (>230 cm2) tandem LSC based on two types of nearly reabsorption-free quantum dots spectrally tuned for optimal solar-spectrum splitting. This prototype device exhibits a high optical quantum efficiency of 6.4% for sunlight illumination and solar-to-electrical power conversion efficiency of 3.1%. In conclusion, the efficiency gains due to the tandem architecture over single-layer devices quickly increase with increasing LSC size and can reach more than 100% in structures with window sizes of more than 2,500 cm2.

Figure 1 | Figure 1 |: The concept of solar-spectrum splitting in a tandem LSC. a, A short-wavelength portion of the solar spectrum is absorbed by LSC’s first-layer (LSC-1) and the reemitted light (orange arrows) is guided towards edge-mounted PVs. The longer-wavelength portion of the solar spectrum transmitted through LSC-1 is harvested bymore » LSC-2 equipped with its own set of PVs. For the best performance, this scheme should utilize band-gap-matched solar cells (PV-1 and PV-2; left). However, as discussed in the text, the overall LSC performance can be enhanced even with the same type of PVs used for both layers (right). b, The absorption (purple) and PL (orange) spectra of Mn2+-doped CdxZn1-xS/ZnS QDs used in LSC-1 along with the AM 1.5G solar spectrum (grey shading) and a typical Si PV external quantum efficiency (EQE) spectrum (green dashed line); top. The absorption (brown) and PL (red) spectra of CuInSe2/ZnSQDs used in LSC-2 along with the AM 1.5G spectrum filtered by LSC-1; bottom.« less
