Extended Data Fig. 2: Optical data for CO2-treated spiro-OMeTAD:LiTFSI.
From: CO2 doping of organic interlayers for perovskite solar cells
a, b, Transmittance and reflectance (a) and absorptance (b) spectra of the CO2-treated spiro-OMeTAD:LiTFSI film. The standardized absorptance ratio (SAR) is calculated from the ratio of absorptance at 521 nm and 407 nm.
