Correction to “Increase the Long‐Wavelength Absorption for Carbon‐Electrode Based Hole‐Conductor‐Free Perovskite Solar Cells by Thicker Perovskite Films”

In the title of the article, Figure 4 has been updated as follows: Figure 4. SEM images of PVSK with PbI 2 being spin-coated for: a) 30s, and b) 240s.c) Statistics on the grain size of PVSK.d) Typical XRD patterns of PVSK.e) Typical current density-voltage curves of champion sample (AM 1.5 G, 100 mW cm -2). PCE distribution of CPSCs assembled from PbI 2 being spin-coated for 30 s f) and 240 s g).h) Quasi-maximum power point tracking (Q-MPPT) curves.(i) and (j) Stability test (25C, 40 RH%, without encapsulation); "FS / RS" in Figure 4 (i) and (j) represents "Forward / Reverse Scan", respectively.
