Over 20% PCE perovskite solar cells with superior stability achieved by novel and low-cost hole-transporting materials

Shaik Mohammed Zakeeruddin, Jingshan Luo, Chenyi Yi, Dongqin Bi, Norman Pellet, Xiong Li, Fei Zhang, Hongwei Zhu, Shilong Wang, Ziyun Wang

The exploration of alternative low-cost molecular hole-transporting materials (HTMs) for both highly efficient and stable perovskite solar cells (PSCs) is a relatively new research area. Two novel HTMs using the thiophene core were designed and synthesized ...

Hill climbing hysteresis of perovskite-based solar cells: a maximum power point tracking investigation

Michael Graetzel, Shaik Mohammed Zakeeruddin, Fabrizio Giordano, Joachim Maier, Mohammad Ibrahim Dar, Norman Pellet

The surge of the power conversion efficiency of metal halide lead perovskite solar cells comes with concerns, such as the long-term ecotoxicity of lead compounds, their sensitivity toward moisture and oxygen, or the scarcity of some of their components. Mo ...

A Model-Based Filtering Strategy to Reconstruct the Maximum Power Generation of Curtailed Photovoltaic Installations: application to forecasting

Mario Paolone, Fabrizio Sossan, Enrica Scolari

In this paper, we propose a model-based filtering strategy to reconstruct the maximum power production of a PV power plant thanks to integrating measurements of the PV cell temperature, system DC voltage and DC current. The filter relies on a reversed phys ...

Advances in Vanadium-Based Catalyst Research for the Selective Catalytic Reduction of NOx by NH₃

Adrian Marberger

The most efficient after-treatment technology for reducing harmful NOx emissions from stationary and mobile sources of diesel exhaust is the selective catalytic reduction (SCR) of NOx with ammonia (NH3). Vanadium-based SCR catalysts reduce NOx selectively ...

Incorporation of rubidium cations into perovskite solar cells improves photovoltaic performance

Shaik Mohammed Zakeeruddin, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Michael Saliba, Antonio Abate, Juan-Pablo Correa-Baena, Konrad Domanski, Jiyoun Seo, Amita Ummadisingu, Taisuke Matsui

All of the cations currently used in perovskite solar cells abide by the tolerance factor for incorporation into the lattice. We show that the small and oxidation-stable rubidium cation (Rb+) can be embedded into a "cation cascade" to create perovskite mat ...

Efficient Monolithic Perovskite/Silicon Tandem Solar Cell with Cell Area >1 cm

Christophe Ballif, Arnaud Walter, Stefaan De Wolf, Björn Niesen, Jérémie Werner, Johannes Peter Seif, Luc Fesquet, Ching-Hsun Weng

Monolithic perovskite/crystalline silicon tandem solar cells hold great promise for further performance improvement of well-established silicon photovoltaics; however, monolithic tandem integration is challenging, evidenced by the modest performances and s ...

Efficient silicon solar cells with dopant-free asymmetric heterocontacts

Christophe Ballif, Jonas Geissbühler, Stefaan De Wolf

A salient characteristic of solar cells is their ability to subject photo-generated electrons and holes to pathways of asymmetrical conductivity-'assisting' them towards their respective contacts. All commercially available crystalline silicon (c-Si) solar ...
