Hybrid Graphene-Metal Oxide Solution Processed Electron Transport Layers for Large Area High-Performance Organic Photovoltaics

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:PC70BM for both single cell and module photovoltaic devices. As a result, the power con...

Zusammenfassung: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:PC70BM 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.
