In contrast to the blend casting (BC) method, sequential deposition (SD) organic solar cell (OSC) offer the advantage of independently engineering the donor and acceptor layers, thereby enabling better control over nanoscale morphology. However, it is essential to consider that individual engineering of the donor and acceptor layers can be influenced by various factors, which may complicate the overall process. In this study, we fabricated an SD OSC using PM6 as the electron donor material and Y6 as the electron acceptor material, along with an additional third component. We investigated the impact of this third component on the device's performance. To examine the morphology of the active layer, we utilized atomic force microscopy (AFM). Subsequently, we analyzed the excited-state dynamics using photoluminescence (PL) and time-correlated single photon counting (TCSPC). Furthermore, we explored the charge carrier dynamics using nanosecond transient absorption spectroscopy (ns-TAS).
