Material Development for Perovskite/Silicon Tandem Photovoltaics

The developed world is built on the fact that energy is readily available and functionally infinite. The electricity from the wall, the gas at the station, and the heat in our homes are reliable and low-cost. But this comfort is so far only possible throug ...

Electrical Losses Mitigation in Silicon Heterojunction Solar Cells

Laurie-Lou Senaud

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 ...

Development of Highly Efficient Perovskite-on-Silicon Tandem Solar Cells

Florent Sahli

Crystalline Silicon (c-Si) solar cells are dominating the photovoltaic (PV) market. Owing to their large manufacturing capacity, reliability and efficiency, c-Si solar cells are now cost-competitive with other non-renewable electricity sources in many plac ...

Stress mitigation for adhesively bonded photovoltaics with fibre reinforced polymer composites in load carrying applications

Thomas Keller, Yu Bai

Structural loads, especially in-plane compression, may cause local buckling and debonding of the photovoltaic (PV) cells that are mechanically integrated with structural members and this may lead to degradation in their electrical performance. This paper p ...

Exploring co-sputtering of ZnO:Al and SiO2 for efficient electron-selective contacts on silicon solar cells

Christophe Ballif, Quentin Thomas Jeangros, Mathieu Gérard Boccard, Monica Morales Masis, Sihua Zhong, Weiliang Wu

In recent years, considerable efforts have been devoted to developing novel electron-selective materials for crystalline Si(c-Si) solar cells with the attempts to simplify the fabrication process and improve efficiency. In this study, ZnO:Al (AZO) is co-sp ...

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 ...

Full-Area Passivating Contacts with High and Low Thermal Budgets: Solutions for High Efficiency c-Si Solar Cells

Gizem Nogay

Today more than 90% of the global PV market is covered by c-Si solar cells which are limited by recombination losses at the metal-semiconductor interface. This recombination path can be avoided by separating the metal from the c-Si wafer by introducing a b ...

Review: Progress in solar cells from hydrogenated amorphous silicon

Christophe Ballif, Franz-Josef Haug, Michael Elias Stückelberger, Rémi Biron

Hydrogenated amorphous silicon (alpha-Si:H) has been used for decades doped and as intrinsic absorber layers in thin-film silicon solar cells. Whereas their effiency was improved for a long time by the deposition of higher quality absorber layers, recent i ...

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

Christophe Ballif, Alessandro Francesco Aldo Virtuani, Hengyu Li, Laure-Emmanuelle Perret Aebi, Fanny Sculati-Meillaud, Eleonora Annigoni, 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 ...
