Figure 5: Solar cell performance and stability.
From: Conjugated polyelectrolyte hole transport layer for inverted-type perovskite solar cells
(a) Current density–voltage (J–V) curves, (b) EQE, (c) efficiency distribution diagram and (d) device stability of ipero-SCs with PEDOT:PSS and CPE-K under ambient air condition. Inset table of a indicates solar cell parameters, JSC (mA cm−2), VOC (V), FF and PCE (%). Inset images of d exhibit the photos of real devices with PEDOT:PSS and CPE-K after air exposure for 12 h.
