摘要：

Organic-inorganic halide perovskite solar cells (PSCs) still suffer from the issues of poor reproducibility and inferior stability despite of their considerable increase in efficiency. Here, we demonstrate planar PSCs with improved device characteristics and stability simultaneously by introducing a cross-linkable [6,6]-phenyl-C₆₁-butyric styryl dendron ester (PCBSD) into CH₃NH₃PbI_xCl_3-x perovskites. The cross-linkable merit of C-PCBSD can enhance the crystallization of perovskites and address the issue of low electron extraction efficiency. In addition, the anti-solvent network of C-PCBSD facilitates the sequential solution process and avoids to be washed by the solvent used in upper layer. The C-PCBSD network could resist the moisture incursion to prevent the interfaces from erosion, and to passivate the voids or pinholes generated in the bulk active layer. As a result, an outstanding PSC with the power conversion efficiency of 17.21% is achieved with evidently improved cell stability.
