Embracing wind power in the solar PV-dominated Swiss landscape

Christophe Ballif, Alejandro Pena Bello, Nicolas Würsch, Marine Dominique Cauz

The Swiss energy transition, characterized by the nuclear phase-out, relies mainly on the integration of solar photovoltaic (PV), mostly because wind technology faces challenges in local public acceptance. This study aims to analyse Swiss PV and wind gener ...

Boron-emitter development for TOPCon c-Si solar cells based on plasma-deposited boron diffusion source and poly-Si(n) passivating contact

Christophe Ballif, Franz-Josef Haug, Julien Hurni, Ezgi Genç

The n-type TOPCon technology is currently the leading approach in the industry. Generally, it involves two high-temperature steps that can result in long cycle times and expensive processes. In this context, we propose a lean manufacturing process based on ...

Characterization of Lightweight Polymeric Honeycomb Structures for Use as Backsides in Glass‐Free PV Modules

Christophe Ballif, Antonin Faes, Umang Bhupatrai Desai

In densely populated or mountainous countries where installation of large‐scale solar plants is challenging, photovoltaic (PV) modules in building applications offer a solution by transforming passive surfaces into energy‐generating systems. The need for f ...

Self-Aligned Silica Nanoparticle Rear Reflectors for Single-Junction Si and Perovskite-Si Tandem Solar Cells

Christophe Ballif, Christian Michael Wolff, Deniz Türkay, Kerem Artuk

Infrared light management is crucial to maximize the optical performance of crystalline Si-based single junction and tandem solar cells. For this end, a low refractive index dielectric is typically inserted under the rear metal and an electrical contact is ...

Suppression of Stacking Faults for Stable Formamidinium-Rich Perovskite Absorbers

Christophe Ballif, Ursula Röthlisberger, Aïcha Hessler-Wyser, Christian Michael Wolff, Virginia Carnevali, Nikolaos Lempesis, Lorenzo Agosta, Austin George Kuba, Mostafa Rabie Shlaly Bahr Othman, Kerem Artuk

The poor intrinsic perovskite absorber stability is arguably a central limitation challenging the prospect of commercialization for photovoltaic (PV) applications. Understanding the nanoscopic structural features that trigger instabilities in perovskite ma ...

Detect, Decouple, Optimise: Insights into Solar Photovoltaics Faults and Performance Trends

Christophe Ballif, Hugo James André Quest

With the photovoltaics (PV) market reaching the terawatt scale, assessing the performance of PV systems accurately has become essential. Traditional approaches to fault detection and diagnosis (FDD) and performance loss rate (PLR) evaluation often operate ...

Impact of Rapid Thermal Processing on Bulk Lifetime and Surface Recombination Velocity of Crystalline Silicon With Passivating Tunnel Oxide Contacts

Christophe Ballif, Franz-Josef Haug, Audrey Marie Isabelle Morisset, Sofia Libraro, Julien Hurni, Ezgi Genç

We investigate rapid thermal processing (RTP) as alternative to the prolonged thermal annealing process used to form tunnel-oxide passivating contacts for silicon solar cells. The thermal treatment is generally followed by hydrogenation to passivate defect ...

Stress tolerance of lightweight glass-free PV modules for vehicle integration

Christophe Ballif, Aïcha Hessler-Wyser, Antonin Faes, Jacques Levrat, Umang Bhupatrai Desai, Gianluca Cattaneo, Fahradin Mujovi, Matthieu Despeisse

Electric vehicles (EVs) currently dominate the sales in the automotive market. A big leap in this market can be made by developing a photovoltaic product that can be integrated to an EV, as it can boost the driving range of the EV while reducing the chargi ...

Mapping the charging demand for electric vehicles in 2050 from mobility habits

Christophe Ballif, Alejandro Pena Bello, Noémie Alice Yvonne Ségolène Jeannin, Nicolas Würsch

This paper proposes a method to spatially model and compare charging needs on the European scale considering local disparities in population density, distance to city centres, car ownership and mobility habits. Mobility habits are modelled across Europe in ...
