Carbazole Treated Waterproof Perovskite Films with Improved Solar Cell Performance

Paul Joseph Dyson, Ursula Röthlisberger, Felix Thomas Eickemeyer, Lukas Pfeifer, Haizhou Lu, Virginia Carnevali, Yeonju Kim, Jaeki Jeong, Nikolaos Lempesis, Lorenzo Agosta, Masaud Hassan S Almalki

Surface passivation has been widely employed to suppress non-radiative charge recombination and prevent interfacial charge accumulation in perovskite photovoltaics. In this report, carbazole modified with ammonium iodide connected via alkyl chains of diffe ...

Ion-Dipole Interaction Enabling Highly Efficient CsPbI3 Perovskite Indoor Photovoltaics

Shaik Mohammed Zakeeruddin, Haizhou Lu, Jie Chen, Xiaoyan Wang, Di Zhang, Ziyun Wang, Meng Li, Xingyu Gao

Metal halide perovskites are ideal candidates for indoor photovoltaics (IPVs) because of their easy-to-adjust bandgaps, which can be designed to cover the spectrum of any artificial light source. However, the serious non-radiative carrier recombination und ...

Pseudo-halide anion engineering for alpha-FAPbI3 perovskite solar cells

Haizhou Lu, Jaeki Jeong, Jiyoun Seo

Metal halide perovskites of the general formula ABX3—where A is a monovalent cation such as caesium, methylammonium or formamidinium; B is divalent lead, tin or germanium; and X is a halide anion—have shown great potential as light harvesters for thin-film ...

A combined molecular dynamics and experimental study of two-step process enabling low-temperature formation of phase-pure alpha-FAPbI3

Haizhou Lu, Paramvir Ahlawat, Essa Awadh R Alharbi

It is well established that the lack of understanding the crystallization process in a two-step sequential deposition has a direct impact on efficiency, stability, and reproducibility of perovskite solar cells. Here, we try to understand the solid-solid ph ...

Intermediate Phase Enhances Inorganic Perovskite and Metal Oxide Interface for Efficient Photovoltaics

David Lyndon Emsley, Wolfgang Richard Tress, Yuhang Liu, Haizhou Lu, Ulf Anders Hagfeldt, Dominik Józef Kubicki, Jiahuan Zhang, Zaiwei Wang, Aditya Mishra, Claudia Esther Avalos, Brian Irving Carlsen, Wanchun Xiang, Anand Agarwalla, Mona Shasti, Ziyun Wang

Interfacial modification is crucial to fully develop the potential of semiconductor devices, including the revolutionary halide perovskite-based optoelectronics, such as photovoltaics, light-emitting diodes, and photodetectors. The all-inorganic halide per ...

Compositional and Interface Engineering of Organic-Inorganic Lead Halide Perovskite Solar Cells

Shaik Mohammed Zakeeruddin, Haizhou Lu, Ulf Anders Hagfeldt, Anurag Krishna

Power conversion efficiency (PCE) of the perovskite solar cells (PSCs) has remarkably been increased from3.1%to 25.2%. The fast expansion of the PSCs has been along with the development of compositional and interface engineering, which has been playing a c ...

Vapor-assisted deposition of highly efficient, stable black-phase FAPbI(3) perovskite solar cells

Shaik Mohammed Zakeeruddin, David Lyndon Emsley, Ursula Röthlisberger, Wolfgang Richard Tress, Felix Thomas Eickemeyer, Yuhang Liu, Haizhou Lu, Likai Zheng, Ulf Anders Hagfeldt, Xiong Li, Zaiwei Wang, Fan Fu, Paramvir Ahlawat, Aditya Mishra, Claudia Esther Avalos, Brian Irving Carlsen, Xianfu Zhang, Anand Agarwalla, Ying Yang

Mixtures of cations or halides with FAPbI(3) (where FA is formamidinium) lead to high efficiency in perovskite solar cells (PSCs) but also to blue-shifted absorption and long-term stability issues caused by loss of volatile methylammonium (MA) and phase se ...
