Redirecting wet–interfacial redox pathways for efficient inverted perovskite solar cells
Editor’s summary Abstract Supplementary Materials References and Notes Information & Authors Metrics & Citations Check Access References Figures Tables Media Share Editor’s summary Conjugated hydrazide additives limit the adverse effect of protons from hole-selective contacts with perovskite inks. Liang et al. found that the acidity of carbazole-based phosphonic self-assembled monolayers triggered detrimental iodide redox reactions mediated by the dimethyl sulfoxide used in perovskite precursors.
Phase-homogeneous mixed halide perovskites for stable tandem photovoltaics
|
Abstract Mixed-halide wide-bandgap (WBG) perovskites needed in tandem photovoltaics suffer from phase segregation, even at the time of initial film formation – the result of asymmetric nucleation of I-rich and Br-rich phases1-3.

Scientists Develop Hybrid Interlayer Enabling 21% Efficiency in Organic Solar Cells
Researchers from the University of Chinese Academy of Sciences (UCAS) and their collaborators reported an inorganic/organic hybrid cathode interfacial layer (CIL), which enabled a high-power conversion efficiency (PCE) of 21.0%, with a certified efficiency of 20.8%, representing the highest values recorded for organic solar cells (OSCs) to date. The study was published in Nature Materials on July 18.
Experimental Study on the Compressive Behavior of Fiber-Reinforced Ceramsite Concrete
1. Introduction Ceramsite concrete is a kind of lightweight aggregate concrete (hereinafter referred to as LAC), which is prepared by replacing the coarse aggregate in traditional concrete with ceramsite.
High Performance All-Polymer Solar Cells Enabled with Solvent and Solid Dual Additives
High Performance All-Polymer Solar Cells Enabled with Solvent and Solid Dual Additives Morphology optimization of photoactive layer plays a crucial role in fabricating high-performance polymer solar cells (PSCs). When an active layer is cast from solution, the unique properties of the donor and acceptor materials often lead to either excessive or insufficient phase separation, which adversely affect the performance of the device.
