The source data files include the processed data that can be directly used for generating the corresponding figures in the manuscript. Methodology: Angle-resolved reflection measurements are taken for characterizing polariton dispersion. The ultrafast transient absorption (TA) spectroscopy is used to study the influence of the “open cavity” system with polariton on the charge generation dynamics of the donor-acceptor bilayer and blend systems. Files inventory: - Source data in Microsoft Excel and txt file for each figure, including the data files for angle-resolved reflection, data for the global analysis and lifetime density analysis.
