摘　　要：The device configuration with mesoporous titanium dioxide(m-TiO2)has garnered considerable attention as a promising solution for high-stable perovskite and dye-sensitized solar cells,although its application in organic solar cells remains unexplored.In this communication,we have incorporated this structure into both bulk-heterojunction(BHJ)and single-component organic solar cells(SCOSCs).Surprisingly,mesoporous OSCs(M-OSCs)demonstrate a deteriorative efficiency in BHJ-type cells,whereas this configuration succeeds in SCOSCs,exhibiting competitive performance with planar OSCs(P-OSCs).This pioneering study has resulted in a competitive power conversion efficiency of 9.67%for m-TiO_(2)-based cells,marking a significant milestone in the advancement of OSCs.Importantly,profiting from the better ultraviolet resistance of m-TiO_(2)than zinc oxide,this M-OSC exhibits superior photostability than that of P-OSCs when subjected to continuous one-sun(AM1.5G)illumination.In its entirety,this research not only introduces the concept of M-OSCs for the first time but also unveils a novel device architecture poised to address the long-term stability concerns within the realm of OSCs.
