Abstract Low-temperature processed electron transport layer (ETL) of TiO 2 that is widely used in planar perovskite solar cells (PSCs) has inherent low carrier mobility, resulting insufficient photogenerated and thus recombination loss at buried interface. Herein, we demonstrate an effective strategy laser embedding p-n homojunctions the ETL to accelerate PSCs, through localized build-in electric fields enables boosted mobility by two orders magnitude. Such found significantly helpful for...
Abstract Managing residual stress in hybrid perovskites is crucial for achieving mechanically stable perovskite solar cells (PSCs) with high power conversion efficiency (PCE), while challenges remain synchronous regulation multiple dimensions during solution‐processing. Herein, a grain‐boundary‐lubricating strategy demonstrated to relieve within films—both in‐plane and out‐of‐plane—for enhancing the mechanical integrity of PSCs. As proof concept, laser‐manufactured multilayer nanolubricants...
Abstract Solution‐processed polycrystalline perovskite films are favorable for low‐cost manufacturing of solar cells (PSCs). However, multiple‐energy‐level trap states in perovskites can trigger ionic migration and degrade device efficiency. Herein, a multidentate‐anchoring strategy by introducing 6‐thioguanine as an additive is employed to enable omnibearing molecular locking the lattice. Theoretical calculations indicate that increase formation energy defects including I vacancy, Pb...

Yet, most research in mechanical been limited the ad hoc design of simple logic gates not fully achieved implementation arithmetic computation within an electricity‐free framework. Additionally, progress...
Abstract Soft material‐based robots, known for their safety and compliance, are expected to play an irreplaceable role in human‐robot collaboration. However, this expectation is far from real industrial applications due complex programmability poor motion precision, brought by the super elasticity large hysteresis of soft materials. Here, a collaborative robot (Soft Co‐bot) with intuitive easy programming contact‐based drag teaching, also exceptional repeatability (< 0.30% body length)...
Time angle of arrival (AoA) and time difference (TDOA) are two widely used methods for solving dynamic signal source localization (DSSL) problems, where the position a moving target is determined by measuring signal's arrival, respectively. In robotic manipulator applications, accurate real-time joint information crucial tasks such as trajectory tracking visual servoing. However, propagation acquisition susceptible to noise interference, which poses challenges systems. To address this issue,...
