Quantifying and modeling the impact of interconnection failures on the electrical performance of crystalline silicon photovoltaic modules

Christophe Ballif, Antonin Faes, Jacques Levrat, Alessandro Francesco Aldo Virtuani, Matthieu Despeisse, Fanny Sculati-Meillaud, Eleonora Annigoni

Failures in the metallic interconnections are among the main degradation modes for photovoltaic modules. Fatigue accumulation due to thermomechanical stresses can result in deterioration of the solder joints or in broken ribbons. In this paper, we first qu ...

Modeling potential-induced degradation (PID) in crystalline silicon solar cells: from acceleratea-aging laboratory testing to outdoor prediction

Christophe Ballif, Eleonora Annigoni, Alessandro Francesco Aldo Virtuani, Hengyu Li, Laure-Emmanuelle Perret Aebi, Fanny Sculati-Meillaud, Marko Jankovec, Federico Paolo Galliano

We present a mathematical model to predict the effect of potential-induced degradation (PID) on the power output of c-Si modules in different climates. For the experimental part, we manufacture mini-modules made of two c-Si p-type cells, and use accelerate ...

In-Situ Monitoring of Moisture Ingress in PV Modules Using Digital Humidity Sensors

Christophe Ballif, Fanny Sculati-Meillaud, Hengyu Li, Laure-Emmanuelle Perret Aebi, Eleonora Annigoni, Marko Jankovec, Federico Paolo Galliano

A new in-situ moisture monitoring technique for photovoltaic (PV) modules is proposed using miniature digital humidity and temperature sensors. The sensors were embedded in three different ethylene-vinyl-acetate (EVA) stacks and proved to be resistant to l ...

Self-Patterned Nanoparticle Layers for Vertical Interconnects: Application in Tandem Solar Cells

Christophe Ballif, Franz-Josef Haug, Aïcha Hessler-Wyser, Mathieu Gérard Boccard, Björn Niesen, Michael Elias Stückelberger, Fanny Sculati-Meillaud, Nicolas Blondiaux, Raphaël Pugin, Emmanuel Scolan

We demonstrate self-patterned insulating nanoparticle layers to define local electrical interconnects in thin-film electronic devices. We show this with thin-film silicon tandem solar cells, where we introduce between the two component cells a solution-pro ...

Optimized short-circuit current mismatch in multi-junction solar cells

Christophe Ballif, Matthieu Despeisse, Mathieu Gérard Boccard, Grégory Bugnon, Fanny Sculati-Meillaud, Maximilien Joseph Marie Bonnet-Eymard

Multi-junction photovoltaic devices include two or more component sub-cells which are electrically interconnected in series. At any power point, the current output of the total device is limited by the sub-cell with the smallest current density. Therefore, ...

Input silane concentration effect on the a-Si:H to uc-Si:H transition width

Christophe Ballif, Christoph Hollenstein, Grégory Bugnon, Andrea Feltrin, Benjamin Strahm, Fanny Sculati-Meillaud

In this work the microstructure transition width from amorphous to microcrystalline silicon is discussed. It is shown that the width of the transition depends on the input silane concentration level and indirectly on the silane depletion level. The higher ...

Influence of ion bombardment on microcrystalline silicon material quality and solar cell performances

Christophe Ballif, Grégory Bugnon, Julien Claude Bailat, Andrea Feltrin, Fanny Sculati-Meillaud

Microcrystalline hydrogenated silicon growth with VHF-PECVD was examined in an industrial type parallel plate KAITM reactor. The influence of pressure on material quality was studied in single junction solar cells. Solar cells with their intrinsic layer pr ...
