Transient Photovoltage Measurements on Perovskite Solar Cells with Varied Defect Concentrations and Inhomogeneous Recombination Rates

Wolfgang Richard Tress, Zaiwei Wang, Brian Irving Carlsen, Firouzeh Ebadi Garjan

In all kinds of solar cells, transient photovoltage (TPV) decay measurements have been used to determine charge carrier lifetimes and to quantify recombination processes and orders. However, in particular, for thin-film devices with a high capacitance, the ...

Mitigation of Vacuum and Illumination-Induced Degradation in Perovskite Solar Cells by Structure Engineering

Quentin Thomas Jeangros, Fan Fu, Shih-Chi Yang, Yan Jiang

y High specific power, high stowed packing efficiency, low processing cost, and high tolerance against environmental threats (high energy and charged particle radiation) make perovskite solar cell (PSC) a promising candidate for power generation in space. ...

Nanoscale Perovskite-Sensitized Solar Cell Revisited: Dye-Cell or Perovskite-Cell?

Mohammad Khaja Nazeeruddin, So-Min Yoo

A general and straightforward way of preparing few-nanometer-sized well-separated MAPbI(x)Br(3-x) (MA=methylammonium) perovskite photosensitizers on the surface of an approximately 1 mu m thick mesoporous TiO2 photoanode was suggested through a two-step se ...

Green-Emitting Lead-Free Cs4SnBr6 Zero-Dimensional Perovskite Nanocrystals with Improved Air Stability

Mohammad Khaja Nazeeruddin, Giulia Grancini, Valentin Ianis Emmanuel Queloz

We report the synthesis and characterization of nanocrystals of a novel fully inorganic lead-free zero-dimensional perovskite, Cs4SnBr6. Samples are made of crystals with an average size of similar to 20 nm with green emission centered around 530 nm. Inter ...

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 ...

A chain is as strong as its weakest link - Stability study of MAPbI(3) under light and temperature

Michael Graetzel, Ulf Anders Hagfeldt, Michael Saliba, Pankaj Kumar Yadav, Amita Ummadisingu, Silver Hamill Turren Cruz, Philippe Jürgen Holzhey

The stability of perovskite solar cells is a key issue for industrial development. One reason for this is the volatile organic methylammonium (MA) cation, which is prone to degas under elevated temperatures from the perovskite. At the same time, small amou ...

Retarding Thermal Degradation in Hybrid Perovskites by Ionic Liquid Additives

Mohammad Khaja Nazeeruddin, Paul Joseph Dyson, Zhaofu Fei, Mounir Driss Mensi, Felix Daniel Bobbink, Cristina Roldán Carmona, Zhangjun Huang, Marius Franckevicius, Nikita Drigo, Rui Xia

Recent years have witnessed considerable progress in the development of solar cells based on lead halide perovskite materials. However, their intrinsic instability remains a limitation. In this context, the interplay between the thermal degradation and the ...

How far does the defect tolerance of lead-halide perovskites range? The example of Bi impurities introducing efficient recombination centers

Wolfgang Richard Tress, Simone Meloni, Björn Niesen, Juan-Pablo Correa-Baena, Zaiwei Wang, Chien-Jen Yang, Mozhgan Yavari, Firouzeh Ebadi Garjan

One of the key properties of lead-halide perovskites employed in solar cells is the defect tolerance of the materials, in particular regarding intrinsic point defects, which mainly form shallow traps. Considering that high luminescence yields and photovolt ...

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 ...
