Kinetic Management of Vertical Phase Separation via Thermal Annealed Donor-Assisted Sequential Deposition Enables 20.81% Efficiency in Organic Solar Cells.
Sequential deposition (SD) process has emerged as a key method for precisely controlling the active layer morphology, which is crucial for enhancing the photovoltaic performance of organic solar cells (OSCs). However, conventional SD methods often face challenges such as interfacial erosion and disordered crystallizati...
