Why choosing the right partner is important: stabilization of ternary Cs(y)GUA(x)FA((1-y-x))PbI(3)perovskites

Ursula Röthlisberger, Marko Mladenovic, Ariadni Boziki

Lead halide perovskites with mixtures of monovalent cations have attracted wide attention due to the possibility of preferentially stabilizing the perovskite phase with respect to photovoltaically less suitable competing phases. Here, we present a theoreti ...

Local Structure and Dynamics in Methylammonium, Formamidinium, and Cesium Tin(II) Mixed-Halide Perovskites from Sn-119 Solid-State NMR

David Lyndon Emsley, Dominik Józef Kubicki, Daniel Prochowicz

Organic-inorganic tin(II) halide perovskites have emerged as promising alternatives to lead halide perovskites in optoelectronic applications. While they suffer from considerably poorer performance and stability in comparison to their lead analogues, their ...

Mechanoperovskites for Photovoltaic Applications: Preparation, Characterization, and Device Fabrication

Pankaj Kumar Yadav, Daniel Prochowicz

Hybrid organic-inorganic metal halide perovskites (MHPs) have emerged as excellent absorber materials for next generation solar cells owing to their simple solution-processed synthesis and high efficiency. This breakthrough in photovoltaics along with an a ...

Performance of perovskite solar cells under simulated temperature-illumination real-world operating conditions

Michael Graetzel, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Konrad Domanski, Essa Awadh R Alharbi, Brian Irving Carlsen, Anand Agarwalla

Since reaching 20% efficiency, research in perovskite photovoltaics has shifted from a race for efficiency to a race for stability. For efficiency, the standard test conditions set the rules for the race. However, the term 'stability' is used very broadly ...

Effect of Thermal Cycling on the Structural Evolution of Methylammonium Lead Iodide Monitored around the Phase Transition Temperatures

László Forró, Endre Horvath, Alla Arakcheeva, Gaétan Charles Antoine Giriat, Anastasiia Glushkova, Konstantins Mantulnikovs, Konstantin Semeniuk

Optoelectronic devices and solar cells based on organometallic hybrid perovskites have to operate over a broad temperature range, which may contain their structural phase transitions. For instance, the temperature of 330 K, associated with the tetragonal-c ...

Europium-Doped CsPbI2Br for Stable and Highly Efficient Inorganic Perovskite Solar Cells

Michael Graetzel, David Lyndon Emsley, Giovanni Dietler, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Jingshan Luo, Dominik Józef Kubicki, Daniel Prochowicz, Zaiwei Wang, Jiangtao Zhou, Seckin Akin, Wanchun Xiang

All-inorganic perovskite films hold promise for improving the stability of perovskite solar cells (PSCs). However, the 3D alpha phase of narrow-bandgap inorganic perovskites is thermodynamically unstable at room temperature, limiting the development of hig ...

Dopant-Free Hole-Transporting Polymers for Efficient and Stable Perovskite Solar Cells

Shaik Mohammed Zakeeruddin, Wolfgang Richard Tress, Michael Saliba

A series of novel polymers (P1P6) derived from the combination of different units (including thiophene, triarylamine, and spirobifluorene) were successfully synthesized, completely characterized, and used as hole-transporting materials (HTMs) for perovskit ...

Thermodynamic re-assessment of the Zn–P binary system

Anna Fontcuberta i Morral, Elias Zsolt Stutz, Mahdi Zamani, Simon Robert Escobar Steinvall

Thermodynamic phase diagrams are the cornerstones to develop synthesis of new materials. Zinc phosphide has evolved into a prospective semicontuctor for next generation solar cells, thanks to its abundance and functional properties. Here we derive an optim ...
