Heatmap from Scientific Research

Decreases in PCE can be significantly reduced, due to the control of drying rates via CN drying, as seen in PCE-heatmap (b). Significantly more of the perovskite thin film is optimally dried (yellow color code) directly under the nozzle centers and the solution is only accumulated on the far edges during the drying process. CorrespondingJsc-,Voc- and FF-heatmaps of CN- and slot jet-dried PSCs are shown in, FigureS4(Supporting Information).
