Congratulations to Jingjing, who won the 2026 SAOT Student Award!
Jingjing has been awarded the SAOT Student Award 2026 for her paper Decoding Interfacial Charge-Carrier Dynamics in Integrated Perovskite/Organic Solar Cells via Numerical Modeling published in Advanced Energy Materials.
In this work, she establishes a unified physical framework to understand how interfacial charge dynamics govern the performance of emerging integrated perovskite/organic solar cells (I-POSCs). The study reveals how energy-level alignment between the perovskite and organic bulk heterojunction layers determines photocurrent, photovoltage, and fill factor: Type-II alignment benefits current extraction, reverse Type-II alignment helps preserve photovoltage, while the intermediate Type-I regime is strongly limited by fill-factor losses.
The work further identifies bimolecular recombination in the organic bulk heterojunction as a key loss channel and shows that suppressing this recombination can broaden the tolerable energy-alignment window. At the same time, it clarifies that I-POSCs remain fundamentally within the single-junction framework, providing the community with a realistic picture of their true performance potential.
