Extended Data Fig. 9: MPP traces for solar cells with pristine spiro-OMeTAD:LiTFSI, spiro-OMeTAD:LiTFSI:Co(III)TFSI, and CO2-treated spiro-OMeTAD:LiTFSI as an HTL.
From: CO2 doping of organic interlayers for perovskite solar cells

MPP was collected every 350 ms under continuous light illumination (100 mW cm−2, AM1.5G) with neither a UV cut-off filter nor a temperature controller. Raw data, including spikes that might originate from a lamp power instability, are presented.
