Fig. 4: Solar cell performance of CQD devices intervened by ambient water.
From: The effect of water on colloidal quantum dot solar cells
a J−V curves of CQD solar cells fabricated through the spin coating and CA under dry air and humid air (RH ~50%–60%), measured under AM 1.5 G solar simulator. b Light-intensity-dependent electron recombination lifetime constants for CQD devices. The relative Bode plots are shown in Supplementary Fig. 18. c–e Band diagrams for CQD cells at VMPP condition for (c) CA devices and (d) spin-coated devices prepared under dry air and (e) under humid air, where EFn is the electron quasi-Fermi level, and EFp is the hole quasi-Fermi level. f Stability of CQD devices under room temperature or under continuously heating at 85 °C in ambient air. The parameters evolutions within the early hours are inserted in each graph.
