Lead immobilization for environmentally sustainable perovskite solar cells

Michael Graetzel, Antonio Abate, Hui Zhang

Lead halide perovskites are promising semiconducting materials for solar energy harvesting. However, the presence of heavy-metal lead ions is problematic when considering potential harmful leakage into the environment from broken cells and also from a publ ...

High-Stable Lead-Free Solar Cells Achieved by Surface Reconstruction of Quasi-2D Tin-Based Perovskites

Michael Saliba, Guixiang Li, Antonio Abate, Feng Yang, Meng Li, Xingyu Gao, Rui Zhu, Zhe Li

Tin halide perovskites are an appealing alternative to lead perovskites. However, owing to the lower redox potential of Sn(II)/Sn(IV), particularly under the presence of oxygen and water, the accumulation of Sn(IV) at the surface layer will negatively impa ...

Robust Inorganic Hole Transport Materials for Organic and Perovskite Solar Cells: Insights into Materials Electronic Properties and Device Performance

Mohammad Khaja Nazeeruddin, Tom Theodorus Antonius Lummen, Antonio Abate

Interfaces in perovskite and organic solar cells play a central role in advancing efficiency and prolong device durability. They improve charge transport/transfer from the absorber layer to the collecting electrodes, while also blocking the opposite charge ...

Bi-functional interfaces by poly(ionic liquid) treatment in efficient pin and nip perovskite solar cells

Mohammad Khaja Nazeeruddin, Giulia Grancini, Christian Michael Wolff, Filippo de Angelis, Albertus Adrian Sutanto, Antonio Abate, Pietro Caprioglio

Approaches to boost the efficiency and stability of perovskite solar cells often address one singular problem in a specific device configuration. In this work, we utilize a poly(ionic liquid) (PIL) to introduce a multi-functional interlayer to improve the ...

Consensus statement for stability assessment and reporting for perovskite photovoltaics based on ISOS procedures

Michael Graetzel, Mohammad Khaja Nazeeruddin, Shaik Mohammed Zakeeruddin, Wolfgang Richard Tress, Kai Zhu, Ulf Anders Hagfeldt, Michael Saliba, Antonio Abate, Henry Snaith, Konrad Domanski

Improving the long-term stability of perovskite solar cells is critical to the deployment of this technology. Despite the great emphasis laid on stability-related investigations, publications lack consistency in experimental procedures and parameters repor ...

Halogen-bond driven self-assembly of perfluorocarbon monolayers on silicon nitride

Nicola Marzari, Antonio Abate, Ngoc Linh Nguyen

The self-assembly of a single layer of organic molecules on a substrate is a powerful strategy to modify surfaces and interfacial properties. Thiolates, silanes, phosphonates and carboxylates are widely used head-groups to link organic molecules to specifi ...
