Fabrication of hole-conductor-free perovskite solar cells based on Al doped ZnO and low-cost carbon electrode

Hole-conductor-free perovskite solar cells were fabricated with Al-doped ZnO (AZO) nanostructure as electron transport layer and low-cost commerical carbon paste as counter electrode. In this method perovskite infiltrated into the AZO nanostructure through the carbon electrode which was prepared usi...
