Abstract

Charge-transport-layer-free (CTL-free) perovskite solar cells have attracted much interest due to their simple device architecture and facile fabrication methods. However, the low efficiency hampers their practical applications. Most recently, a perovskite hetero-bilayer structure was introduced as absorbing layer and embedded between electrodes to form solar cells with efficiency surpassing 16%, which sets the record for all CTL-free perovskite solar cells. Here, we highlighted several main points in this work, as well as propose perspective for future CTL-free solar cell investigations.
