New Thin-Film Material Achieves Both High Efficiency and Durability in Tandem Solar Cells

Their findings were published in Advanced Energy Materials on April 8, 2025.

Abstract Perovskite/organic tandem solar cells (POTSCs) are promising candidates for surpassing the Shockley-Queisser limit through reduction of thermalization losses. However, wide bandgap perovskite solar cells (WBG PSCs), which function... Read More

AI Reinforcement Learning Breakthrough for Accurate Decision-Making in Unknown Situations

Their ICLR paper titled "Flat Reward in Policy Parameter Space Implies Robust Reinforcement Learning" has been selected as Oral, which is Top 1.8% of all submissions.

Abstract Investigating flat minima on loss surfaces in parameter space is well-documented in the supervised learning context, highlighting its advantages for model generalization. However, limited attention has been paid to the reinforcemen... Read More

Breakthrough in Self-Assembling Molecules Enhances Efficiency and Stability of PSCs

The findings have been made available online in Angew. Chem., Int. Ed. ahead of its formal publication.

Abstract The photovoltaic performance of inverted perovskite solar cells (PSCs) relies on effectively managing the interface between the hole extraction layer and the light-absorbing perovskite layer. In this study, we have synthesised (4-(... Read More
