Abstract

The interface between the perovskite layer and the electron transport layer is an extremely important factor that cannot be ignored in achieving high-performance perovskite photovoltaic technology. However, the void defects of the interface pose a serious challenge for high performance perovskite solar cells (PSCs). To address this, we report a polydentate ligand reinforced chelating strategy to strengthen the stability of buried interface by managing interfacial defects and stress. The gelatin-coupled cellulose (GCC) is employed to manipulate the buried interface. The unique functional groups in GCC synergistically passivate the defects from the surface of SnO2 and the bottom surface of the perovskite layer. Our work demonstrates that by implementing the GCC as a buried interface strategy, it is possible to prepare devices with reduced vacancy states, non-radiative recombination suppression, and excellent optoelectronic performance. At the same time, this work improves the efficiency and stability of PSCs, and provides greater space for device manufacturing.

期刊介绍: Chemical Science is a journal that encompasses various disciplines within the chemical sciences. Its scope includes publishing ground-breaking research with significant implications for its respective field, as well as appealing to a wider audience in related areas. To be considered for publication, articles must showcase innovative and original advances in their field of study and be presented in a manner that is understandable to scientists from diverse backgrounds. However, the journal generally does not publish highly specialized research.
