High‐performance inverted solar cells using various low‐bandgap polymers are achieved by using excellent metal oxide nanoparticles including ZnO and TiO2:Cs nanoparticles as an electron‐transport layer (ETL). Power conversion efficiencies (PCE) as high as 7.3% are achieved with inverted single cells based on PTB7:PC71BM. The results give a guideline for high‐efficiency and stable inverted single‐junction and tandem polymer solar cells.
