英文摘要	We introduce and demonstrate the concept of quantum cutting luminescent solar concentrators (QC-LSCs) using Yb3+-doped perovskite nanocrystals. These NCs feature a photoluminescence quantum yield approaching 200% and virtually zero self-absorption loss of PL photons, defining a new upper limit of 150% for the internal optical efficiency (eta(int)) of LSCs that is almost independent of LSC sizes. An unoptimized 25 cm(2) QC-LSC fabricated from Yb3+-doped CsPbCl3 NCs already displayed an eta(int) of 118.1 +/- 1 6.7% that is 2-fold higher than previous records using Mn2+-doped quantum dots (QDs). If using CsPbClxBr3-x NCs capable of absorbing similar to 7.6% of solar photons, the projected external optical efficiency (eta(ext)) of QC-LSCs can exceed 10% for >100 cm(2) devices, which still remains a challenge in the field. The advantage of QC-LSCs over conventional QD-LSCs becomes especially obvious with increasing LSC sizes, which is predicted to exhibit a more than 4-fold window-size (1 m(2)) devices. efficiency enhancement in the case of window-size (1 m(2)) devices.
