Abstract：

Perovskite　solar　cells　(PSCs)　fabricated　of　TiO2　electron　transporting　material　(ETM)　have　aroused　tremendous　attention,　but　their　power　conversion　efficiency　(PCE)　needs　further　improvements.　In　this　study,　for　the　first　time,　zirconium　(Zr)-doped　brookite　TiO2　nanorods　(ZTO)　are　synthesized　by　a　facile　route　and　subsequently　employed　as　an　ETM　in　PSCs　which　finally　achieves　a　considerable　PCE　of　19.42　%　by　optimizing　all　operating　conditions.　Further　characterizations　have　been　undertaken　to　explore　in　detail　the　effects　of　Zr　doping　on　the　nature　of　the　perovskite　active　layer　and　the　photovoltaic　performance.　As　a　consequence,　the　enhanced　PCE　can　be　ascribed　to　the　high　quality　perovskite　crystals　and　a　more　favorable　energy　level　alignment　between　the　perovskite　layer　and　ZTO　mesoporous　layer.　©　2024　Elsevier　Ltd
