Top) Transient absorption spectra of binary and ternary blend films upon photoexcitation of SiPc6: a RR-P3HT/SiPc6, b PCBM/SiPc6, and c RR-P3HT/PCBM/SiPc6. Bottom) Absorption spectra of SiPc6 singlet excitons (black lines), P3HT hole polarons (orange lines), SiPc6 anions (purple lines), PCBM anions (blue lines), and SiPc6 cations (red lines).
