Enhanced performance of perovskite solar cell via up-conversion YLiF4:Yb, Er nanoparticles
Mounir Driss Mensi, Masaud Hassan S Almalki, Anwar Qasem M Alanazi
We report a simple and effective method for producing lanthanide ion-doped lithium-fluoride-based nanocrystals (YLiF4). We utilized those nanoparticles for up-conversion in fabricated perovskite solar cells. The obtained results shows that the up-conversio ...
Elsevier2024Vapor Deposition of Perovskite Solar Cells
Quentin Jean-Marie Armand Guesnay
Thanks to the continuous improvement of crystalline silicon (c-Si) solar cells, largely dominating the market, photovoltaic electricity is nowadays the cheapest source of energy on the market. Yet, solar energy is far from being completely harvested, as t ...
EPFL2023Molecular dynamics simulations of nucleation and phase transition in halide perovskites
Perovskite solar cells have emerged as the most promising cheaper photovoltaic technology. Besides solar cells, halide perovskites have a wide range of applications due to their remarkable optoelectronic properties. Starting from 3.8% in 2009, solar to the ...
EPFL2022Doped but Stable: Spirobisacridine Hole Transporting Materials for Hysteresis-Free and Stable Perovskite Solar Cells
Mohammad Khaja Nazeeruddin, Pascal Alexander Schouwink, Sanghyun Paek, Cristina Roldán Carmona, Albertus Adrian Sutanto, Hobeom Kim, Marius Franckevicius, Kun-Han Lin, Nikita Drigo, Muhammad Sohail
Four spirobisacridine (SBA) hole-transporting materials were synthesized and employed in perovskite solar cells (PSCs). The molecules bear electronically inert alkyl chains of different length and bulkiness, attached to in-plane N atoms of nearly orthogona ...
AMER CHEMICAL SOC2020alpha-CsPbI(3)Bilayers via One-Step Deposition for Efficient and Stable All-Inorganic Perovskite Solar Cells
Mohammad Khaja Nazeeruddin, Yong Ding, Olga Syzgantseva, Xianfu Zhang, Cheng Liu
The emerging inorganic CsPbI(3)perovskites are promising wide-bandgap materials for application in tandem solar cells, but they tend to transit from a black alpha phase to a yellow delta phase in ambient conditions. Herein, a gradient grain-sized (GGS) CsP ...
2020Surface, Interface, and Bulk Electronic and Chemical Properties of Complete Perovskite Solar Cells: Tapered Cross-Section Photoelectron Spectroscopy, a Novel Solution
Mohammad Khaja Nazeeruddin, Iwan Zimmermann, Thomas Mayer
The surface, interface, and bulk properties are a few of the most critical factors that influence the performance of perovskite solar cells. The photoelectron spectroscopy (PES) is used as a technique to analyze these properties. However, the information d ...
AMER CHEMICAL SOC2020Performance 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 ...
NATURE PUBLISHING GROUP2019Dopant-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 ...
AMER CHEMICAL SOC2019Phosphonic Acid Modification of the Electron Selective Contact: Interfacial Effects in Perovskite Solar Cells
Wolfgang Richard Tress, Ulf Anders Hagfeldt, Juan-Pablo Correa-Baena, Silver Hamill Turren Cruz, Rebecca Hill
The role electron-transport layers (ETLs) play in perovskite solar cells (PSCs) is still widely debated. Conduction band alignment at the perovskite/ETL interface has been suggested to be an important role for the performance of the solar cells. However, l ...
AMER CHEMICAL SOC2019Review on Recent Progress of All-Inorganic Metal Halide Perovskites and Solar Cells
Wolfgang Richard Tress, Wanchun Xiang
All-inorganic perovskites are considered to be one of the most appealing research hotspots in the field of perovskite photovoltaics in the past 3 years due to their superior thermal stability compared to their organic-inorganic hybrid counterparts. The pow ...
