Accelerated Development of Vapor Deposition Technology for Efficient Perovskite Solar Cells via Accurate and Practical Machine Learning Tools

open access: yesAdvanced Science, EarlyView.
Based on rational feature selection, an integrated‐feature dataset is constructed encompassing macro‐ and micro‐feature parameters. Screening and optimization across ten algorithmic models enhanced predictive accuracy and robustness for power conversion efficiency (PCE), yielding an R2 of 0.9464 and RMSE of 1.27%.

The Potential of Servicizing as a Green Business Model [PDF]

open access: yes, 2015
It has been argued that servicizing business models, under which a firm sells the use of a product rather than the product itself, are environmentally beneficial.

Hydrazine‐Mediated Thermally Assisted Photocatalytic Ammonia Decomposition Over Layered Protonated Perovskites

open access: yesAdvanced Science, EarlyView.
Herein, a new catalyst, protonated layered perovskite HPrNb2O7, is presented, which exhibits exceptional photocatalytic activity for solar‐driven ammonia decomposition. Its unique structure facilitates the generation of active sites while extending charge carrier lifetime with input thermal energy. Abstract Photocatalytic ammonia decomposition offers a

Reaction Suppression Between a High‐Ni Cathode Material (NMC622) and Li7La3Zr2O12 on Co‐Sintering for Manufacturing Bulk‐Type All‐Solid‐State Batteries: A New Method and Its Mechanism

open access: yesAdvanced Science, EarlyView.
A bulk‐type all‐solid‐state battery is produced by co‐sintering the proprietary NMC622 and LLZ. This proprietary NMC622 can avoid the formation of impurity phases under co‐sintering. The reduced Ni2+ fraction in NMC622 and the presence of a self‐formed Li2CO3 surface layer result in this outcome. It is possible to realize a rechargeable all‐solid‐state
