摘要
Strain effects on vacancies, electronic states and stability have been disclosed for perovskite structured materials (ABX3) including metal oxides and organic-inorganic hybrids critical for energy storage and generation. Ion substitution has been pursued as an attractive solution to alter the crystallization or induced electronic of organic-inorganic hybrid halide lead perovskite. However, the disorganized structure of perovskite result from inappropriate substitution may cause unwanted phase transition and photo-stability. Herein, we introduce crystallization of restriction ABX3 composition with moderate zinc (Zn) substitution to obtain the ordered and stable CH3NH3(Zn:Pb)I3-xClx crystal, which is achieved via releasing lattice strain during an appropriate lattice constriction within BX6 octahedron. We obtained an unprecedented efficiency of 20.06% under simulated sunlight with facilitating binary metal perovskite of CH3NH3(1Zn:100Pb)I3-xClx. Our results are important to realize scale up and practical applications of efficient planar perovskite solar cells.
