Rationalizing Performance Losses of Wide Bandgap Perovskite Solar Cells Evident in Data from the Perovskite Database
Christian Michael Wolff, Tor Jesper Jacobsson
Metal halide perovskites (MHPs) have become a widely studied class of semiconductors for various optoelectronic devices. The possibility to tune their bandgap (E-g) over a broad spectral range from 1.2 eV to 3 eV by compositional engineering makes them par ...
Weinheim2023The evolution of triphenylamine hole transport materials for efficient perovskite solar cells
In recent years, the dramatic increase in power conversion efficiency (PCE) coupled with a decrease in the total cost of third-generation solar cells has led to a significant increase in the collaborative research efforts of academic and industrial researc ...
ROYAL SOC CHEMISTRY2022The emergence of concentrator photovoltaics for perovskite solar cells
Mohammad Khaja Nazeeruddin, Anurag Roy
The emergence of high-efficiency photovoltaic research is undergoing intense study and is technologically desirable to meet sustainable energy and environmental demand. However, every single solar cell has a theoretical power conversion efficiency limit, a ...
AIP Publishing2021Palliating the efficiency loss due to shunting in perovskite/silicon tandem solar cells through modifying the resistive properties of the recombination junction
Christophe Ballif, Gabriel Christmann, Mathieu Gérard Boccard, Sylvain Nicolay
As the efficiency of commercial crystalline silicon solar cells approaches its maximum theoretical value, tandem architectures are becoming increasingly popular to continue the push to higher photovoltaic performances. Thin-film materials are particularly ...
2021Electrical Losses Mitigation in Silicon Heterojunction Solar Cells
To overcome the worldwide challenges of climate change, photovoltaics is foreseen to play a significant role in the world electricity production. Nowadays, single junction crystalline silicon (c-Si) based solar cells hold the largest share of the global ph ...
EPFL2021Dual Passivation of CsPbI3 Perovskite Nanocrystals with Amino Acid Ligands for Efficient Quantum Dot Solar Cells
Ulf Anders Hagfeldt, Jianhua Liu
Inorganic CsPbI3 perovskite quantum dot (PQD) receives increasing attention for the application in the new generation solar cells, but the defects on the surface of PQDs significantly affect the photovoltaic performance and stability of solar cells. Herein ...
2020Performance 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 GROUP2019Light Management: A Key Concept in High-Efficiency Perovskite/Silicon Tandem Photovoltaics
Christophe Ballif, Florent Sahli, Daniel Anthony Jacobs
The remarkable recent progress in perovskite photovoltaics affords a novel opportunity to advance the power conversion efficiency of market-dominating crystalline silicon (c-Si) solar cells. A severe limiting factor in the development of perovskite/c-Si ta ...
