Extended Data Fig. 8: Summary of the outdoor stability testing located in the KAUST testing site, Saudi Arabia.

Poutput is the power output of the devices under outdoor conditions. The highest Poutput during the first and last day were utilized to compare the outdoor stability, and the devices in the same group were aged under identical real-world climates. The whiskers represent the maximum and minimum values, and the box edges indicate the 75th and 25th percentiles. The center lines in the box-plot chart indicate the mean values. In group 2, the first 4-week outdoor stability database for PM6:N3, PM6:BTP-BO-4Cl, and PM6:BTP-eC9 blends, and the first 60-day outdoor stability database for PM6:Y12, PM6:Y6, and PM6:Y7 blends are available from the previous work11. All the outdoor stability database is available in the source data files provided with this paper.
