Understanding the degradation mechanism and improving thermal stability of organic solar cells are essential for this new photovoltaic technology. In work, we found that high-performance polymer suffer from significant performance decay upon annealing at 150 °C owing to fast VOC FF. We demonstrated process leads a severe chemical reaction MoO3 with Al, forming an Al2O3 barrier layer MoO3/Al interface, which lowers built-in potential (Vbi) consequently reduces charge collection efficiency. Inserting thin C60 interlayer between slows ensures high Vbi efficiency annealed MoO3/C60/Al cells. Such protection effect in device against was also confirmed different photoactive layers metal electrodes, demonstrating generality interfacial layer. Finally, inverted C60-modified anode showed almost no high-temperature hot-press encapsulation, excellent heat tolerance structure.

In this study, two distinct unfused non‐fullerene acceptors (NFAs) are synthesized by arranging them in an A‐D‐D‐A pattern, both containing same D‐D central S, N‐heteroacene but different terminal acceptors, namely BTA ( NFA‐2 ) and IC NFA‐3 ). Their optical electrochemical properties investigated. Both display the high lowest unoccupied molecular orbital energy level, leading to increased open circuit voltage organic solar cells. PBDB‐T is chosen as polymer donor, showing spectral absorption that complements NFAs. The optimized cells, based on PBDB‐T: attained power conversion efficiency of 9.24% 13.50%, respectively. Since characteristics complementary, a small amount added into binary blend, ternary cells 15.24%. rise linked higher values short current fill factor. value efficient use excitons produced transferring from effective exciton dissociation, faster charge extraction, decreased bimolecular trap‐assisted recombination. enhanced FF also processes mentioned earlier. This investigation shows it advantageous separate non‐fused NFAs with spectra complement each other have overlapped PL medium bandgap acceptor along narrow NFA
