Top management team boundary-spanning leadership: Measurement development and its impact on innovative behavior.

With the advancement of digital economy, organizations around the world need to stretch the boundaries of their strategy, business, and knowledge to gain a competitive advantage and achieve sustainable growth. Although boundary-spanning leadership, with a set of practical tools developed by the Center for Creative Leadership (CCL), has been explored over the past 10 years, the comprehensive understanding of top management team boundary-spanning leadership has still reached no consensus. This research focuses on the concept of top management team boundary-spanning leadership (TMTBSL) and its effect on employees' innovative behavior. Study 1 comprises the concept of TMTBSL and the measurement of its development. The classical grounded theory was used to analyze biographical texts and in-depth interview data from local Chinese organizations. We developed a 5-dimension scale with14 items for TMTBSL. In Study 2, we empirically examined the impact of TMTBSL on employees' innovative behavior. The results demonstrate that TMTBSL can promote employee innovative behavior through perceived motivational climate. The theoretical and practical implications are also outlined.

Additive Engineering of the CuSCN Hole Transport Layer for High-Performance Perovskite Semitransparent Solar Cells.

CuSCN has been widely considered a promising candidate for low-cost and high-stable hole transport material in perovskite semitransparent solar cells (STSCs). However, the low conductivity of the solution-processed CuSCN hole transport layer (HTL) hinders the hole extraction and transport in devices, which makes it hard to achieve devices with high performance. Herein, we report a facile additive engineering approach to optimize the p conductivity of CuSCN HTLs in perovskite STSCs. The n-butylammonium iodide additive facilitates the formation of Cu2+ and generates more Cu vacancies in the CuSCN HTL. This realizes a significant enhancement of the hole concentration and p conductivity of the film. Moreover, the additive improves the solubility of the CuSCN precursor solution and results in a uniform coverage on the perovskite active layer. Therefore, the perovskite STSC with a high power conversion efficiency (PCE) of 19.24% has been achieved, which is higher than that of the spiro-OMeTAD (18.83%) and CuSCN (17.45%) counterparts. In addition, the unencapsulated CuSCN-based device retains 87.5% of the initial PCE after 20 days in the ambient atmosphere.
