Modeling of mesoscale phenomena using WRF-BEP-BEM-CIM in a complex region

Jean-Louis Scartezzini, Dasaraden Mauree, Sylvain Labedens

A simulation tool (EcoSim) has been developed to analyse the economic and environmental aspects of the integration of several energy conversion units. For a given investment over 25 years, the tool calculates the self-consumption rate, the autonomy level, ...

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 ...

A method for quantitative nanoscale imaging of dopant distributions using secondary ion mass spectrometry: an application example in silicon photovoltaics

Franz-Josef Haug, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Andrea Ingenito, Gizem Nogay, Mario Joe Lehmann

A method for rapid quantitative imaging of dopant distribution using secondary ion mass spectrometry (SIMS) is described. The method is based on SIMS imaging of the cross-section of a reference sample with a known concentration profile. It is demonstrated ...

Modelling and Forecasting of Photovoltaic Generation for Microgrid Applications: from Theory to Validation

Enrica Scolari

The penetration of stochastic renewable generation in modern power systems requires to reconsider conventional practices to ensure the reliable functioning of the electrical network. Decentralized control schemes for distributed energy resources (DERs) hav ...

Atomic-level passivation mechanism of ammonium salts enabling highly efficient perovskite solar cells

Shaik Mohammed Zakeeruddin, David Lyndon Emsley, Jacques-Edouard Moser, Fabrizio Giordano, Jingshan Luo, Dominik Józef Kubicki, Brennan James Walder, Andrés Burgos Caminal, Essa Awadh R Alharbi, Anwar Qasem M Alanazi, Alexander Roland Uhl

The high conversion efficiency has made metal halide perovskite solar cells a real break-through in thin film photovoltaic technology in recent years. Here, we introduce a straight-forward strategy to reduce the level of electronic defects present at the i ...

35 years of photovoltaics: Analysis of the TISO-10-kW solar plant, lessons learnt in safety and performance-Part 1

Christophe Ballif, Alessandro Francesco Aldo Virtuani, Eleonora Annigoni

The TISO-10-kW solar plant, connected to the grid in 1982, is the oldest installation of this kind in Europe. Its history is well documented, and the full set of modules has been tested indoors at regular intervals over the years. After 35 years of operati ...

Glass-free lightweight PV building elements: solutions to minimize weight and maximize durability

Ana Cristina Oliveira Martins

In densely populated countries, little free land is available for the deployment of photovoltaics (PV) in field installations. In addition, 40% of the world's demand for electricity is related to buildings. These facts provide a strong argument for the acc ...

A morphological based PV generation and energy consumption predictive model for Singapore neighbourhood

Jérôme Henri Kämpf

The Singapore government emphasises the importance of sustainable development of the country and set an ambitious target for the adoption of solar power in 2014. Though solar energy is the most promising renewable energy source for Singapore, there is insu ...
