Due to the advantages of cost-effectiveness and tunable band gap,hole transport layer(HTL)-free CsPbI_(X)Br_(3-X) carbon-based inorganic perovskite solar cells(C-IPSCs)are emerging candidates for both single junction and tandem solar *** of the direct contact between the carbon electrode and the perovskite surface,energy barriers and defects at the interface limit the enhancement of power conversion efficiency(PCE).In this work,we first reported a preparation method of CsPbI_(2.75)Br_(0.25) HTL-free C-IPSCs and developed an effective surface sulfidation regulation(SSR)strategy to promote hole extraction and inhibit non-radiative recombination of inorganic perovskite by 2-(thiocyanomethylthio)benzothiazole(TCMTB)surface *** introduced S^(2-)anions form strong binding with uncoordinated Pb ions,inhibit the perovskite degradation reaction,and effectively passivate the surface *** addition,PbS formed by the SSR strategy constructed a gradient heterojunction,which promoted the arrangement energy levels and enhanced hole *** additional back-surface field is induced at the interface of perovskite by energy band bending,which increases the opencircuit voltage(V_(OC)).As a result,the SSR-based CsPbI_(2.75)Br_(0.25) HTL-free C-IPSCs showed a PCE of 17.88%with a fill factor of 81.56%and V_(OC) of 1.19 V,which was among the highest reported values of CsPbI_(2.75)Br_(0.25) HTL-free C-IPSCs.
