The electron transport layer (ETL) in an organic solar cell is one of the main components that play a crucial role in the separation of charges, improving efficiency, and increasing the lifetime of the solar cells. Herein, solution-processed PBDTTT-CT: PC70BM based organic solar cells were fabricated using PDINO, Titanium Oxide (TiOx), and the mixture of PDINO and TiOx as an ETL. A power conversion efficiency (PCE) of 7.9% was achieved when a mixture of PDINO and TiOx was used as an ETL, which is one of the highest reported efficiency for halogen-free solvent processed PBDTTT-CT:PC70BM based polymer solar cells (PSCs). Furthermore, lower recombination, higher exciton dissociation probability, and longer lifetime were observed from the same device that indicates the selectivity of ETL can effectively improve the performance and stability of the solar cells.
