Zero-dimensional hybrid iodobismuthate derivatives: from structure study to photovoltaic application

Mohammad Khaja Nazeeruddin, Kurt Schenk, Farzaneh Fadaei Tirani, Yi Zhang, Philip Pattison, Peng Gao

The quest for lead-free light-absorbing perovskite materials has long been the target of researchers to make the 'star' material friendly to the commercial market. After a summary of different lead-free solar absorbers, we demonstrate a zero-dimensional io ...

The 16 T Dipole Development Program for FCC and HE-LHC

Pierluigi Bruzzone, Peng Gao, Catherine Elvire L. De Wolf, Luca Bottura, Stephan Russenschuck, Mariusz Juchno, Bernhard Auchmann, Giuseppe Montenero

A future circular collider (FCC) with a center-of-mass energy of 100 TeV and a circumference of around 100 km, or an energy upgrade of the LHC (HE-LHC) to 27 TeV require bending magnets providing 16 Tin a SO-mm aperture. Several development programs for th ...

All that glitters is not gold: Recent progress of alternative counter electrodes for perovskite solar cells

Mohammad Khaja Nazeeruddin, Peng Gao, Xing Li

Although ultrahigh power conversion efficiency (PCE) up to 22.7% has been achieved by solution-processable perovskite solar cells (PSCs), there are still some obstacles that hinder the way of this promising photovoltaic technology to its commercialization. ...

Trash into Treasure: δ-FAPbI3 Polymorph Stabilized MAPbI3 Perovskite with Power Conversion Efficiency beyond 21%

Mohammad Khaja Nazeeruddin, Emad Oveisi, Yi Zhang, Peng Gao, Zhipeng Li

Effective passivation and stabilization of both the inside and interface of a perovskite layer are crucial for perovskite solar cells (PSCs), in terms of efficiency, reproducibility, and stability. Here, the first formamidinium lead iodide (δ-FAPbI3) polym ...

Dimensionality engineering of hybrid halide perovskite light absorbers

Mohammad Khaja Nazeeruddin, Peng Gao

Hybrid halide perovskite solar cells were first demonstrated in 2009 with cell efficiency quickly soaring from below 10% to more than 23% in a few years. Halide perovskites have the desirable processing simplicity but are very fragile when exposed to water ...

From Nano- to Micrometer Scale: The Role of Antisolvent Treatment on High Performance Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Francesco Stellacci, Giulia Grancini, Pascal Alexander Schouwink, Yi Zhang, Peng Gao, Sanghyun Paek, Kyung Taek Cho, Evangelia-Nefeli Athanasopoulou

To date, antisolvent treatment has become one of the most important means to fabricate high efficiency perovskite solar cells (PSCs); however, the few reported antisolvents have not been analyzed on a uniform platform, and there is hitherto no clear reason ...

Unveiling the Concentration-Dependent Grain Growth of Perovskite Films from One- and Two-Step Deposition Methods: Implications for Photovoltaic Application

Mohammad Khaja Nazeeruddin, Yi Zhang, Peng Gao

In order to achieve high-efficiency perovskite solar cells, understanding both the crystal structure and the optoelectronic properties of perovskite layers is of importance. This paper uses crystallization analysis and the modeling study of two different p ...
