Advanced Functional Materials, EarlyView.A non‐annealed process is developed for non‐PEDOT:PSS inverted tin‐lead perovskite solar cells to attain PCE 22.67% for the PTAA‐based device. When PTAA is applied in an all‐perovskite tandem solar cell, a record efficiency of 28.14% is obtained with great stability for the efficiency maintaining 96% of its original value for 500 h under one‐sun ...

Advanced Materials, EarlyView.The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.
