Solution processed core–shell nano‐structures of metal oxide‐reduced graphene oxide (RGO) are used as improved electron transport layers (ETL), leading to an enhancement in photocurrent charge transport in PCDTBT:PC 70 BM for both single cell and module photovoltaic devices. As a result, the power conversion efficiency for the devices with RGO‐metal oxides for ETL increases 8% in single cells and 20% in module devices.
