Exploring the Impedance Spectroscopy in Hole‐Conductor‐Free Mesoscopic Perovskite Solar Cells
Progress in Photovoltaics: Research and Applications, EarlyView.This study employs impedance spectroscopy (IS) to investigate the carrier dynamics of printable perovskite solar cells (p‐MPSCs). The exceptional stability of p‐MPSCs enables reliable IS measurements under various conditions. We develop an equivalent circuit model to analyze the IS data, linking each circuit element to specific dynamic processes.

Grid Optimization of Tunnel Oxide Passivated Back Contact Silicon Solar Cells
Progress in Photovoltaics: Research and Applications, EarlyView.The grid pattern design of tunnel oxide passivated back contact silicon solar cells were optimized via device simulation and the estimated cell efficiency was correlated to the required Ag paste consumption. The absolute efficiency gain of zero‐busbar design over pad‐based contact design is more than 0.1%, with increasing advantage when the Ag paste ...

A Novel Crawling Robot Based on the Hexagonal Mesh Structure and Enhanced PID Control Strategy
Journal of Field Robotics, EarlyView.ABSTRACT The locomotion of crawling robots is similar to that of caterpillars, relying on foot adhesion and body contraction to ensure flexible movement without compromising stability. However, most existing pneumatic soft crawling robots are incapable of simultaneously achieving forward, backward, turning, and climbing capabilities.
