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, Antonio Abate, Feng Yang, Guixiang Li, 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, 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, Christian Michael Wolff, Filippo de Angelis, Antonio Abate, Giulia Grancini, Albertus Adrian Sutanto, 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 ...

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 ...

The effect of illumination on the formation of metal halide perovskite films

Wolfgang Richard Tress, Antonio Abate, Jiyoun Seo, Amita Ummadisingu, Ludmilla Steier, Taisuke Matsui

Optimizing the morphology of metal halide perovskite films is an important way to improve the performance of solar cells(1) when these materials are used as light harvesters(2), because film homogeneity is correlated with photovoltaic performance(3). Many ...

Migration of cations induces reversible performance losses over day/night cycling in perovskite solar cells

Mohammad Khaja Nazeeruddin, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Michael Saliba, Filippo de Angelis, Antonio Abate, Juan-Pablo Correa-Baena, Konrad Domanski, Silver Hamill Turren Cruz, Taisuke Matsui

Perovskites have been demonstrated in solar cells with a power conversion efficiency of well above 20%, which makes them one of the strongest contenders for next generation photovoltaics. While there are no concerns about their efficiency, very little is ...

The rapid evolution of highly efficient perovskite solar cells

Wolfgang Richard Tress, Ulf Anders Hagfeldt, Michael Saliba, Antonio Abate, Juan-Pablo Correa-Baena, Tor Jesper Jacobsson

Perovskite solar cells (PSCs) have attracted much attention because of their rapid rise to 22% efficiencies. Here, we review the rapid evolution of PSCs as they enter a new phase that could revolutionize the photovoltaic industry. In particular, we describ ...

Identifying and suppressing interfacial recombination to achieve high open-circuit voltage in perovskite solar cells

Wolfgang Richard Tress, Ulf Anders Hagfeldt, Michael Saliba, Antonio Abate, Juan-Pablo Correa-Baena, Konrad Domanski, Silver Hamill Turren Cruz, Elham Halvani Anaraki

With close to 100% internal quantum efficiency over the absorption spectrum, photocurrents in perovskite solar cells (PSCs) are at their practical limits. It is therefore imperative to improve open-circuit voltages (VOC) in order to go beyond the current 1 ...
