| 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. |
