Champion Photovoltaic Performance of CsPbI3 and Cs0.95Na0.05PbI3 C-PSCs
(A–D) (A) J-V curves, (B) stabilized power output, (C) IPCE spectra and integrated Jsc, and (D) stability results of CsPbI3 and Cs0.95Na0.05PbI3 C-PSCs that were stored in dry air atmosphere (20°C –35°C and 10%–20% humidity). All devices used for the performance and stability testing were non-encapsulated.
