The electron transport layer in a solar cell is one of the main components which plays a crucial role in the separation of charges and improving the efficiency of the solar cells. Herein, solution-processed organic solar cells (PBDTTT-CT:PC70BM) were fabricated with PDINO, Titanium Oxide, and PDINO:TiOx as an ETL. The effect of different ETLs on the performance of solar cells was observed. An efficiency of 7.94% was achieved when PDINO:TiOx was used as an ETL which is one of the highest reported efficiencies for halogen-free solvent processed PBDTTT-CT:PC70BM polymer solar cells. Meanwhile, lower recombination and higher exciton dissociation probability were observed in PDINO:TiOx based PSCs, as well as the superior stability at 45 oC in air.
