Lay Summary (French)

Lead
L’ensemble des façades des bâtiments en Suisse pourrait générer jusqu'à 3-4 TWh d'électricité par an. Il y a donc un énorme potentiel d’intégration du photovoltaïque (PV) dans le bâtiment. Pourtant, pour diverses raisons, les toitures et encore plus les façades solaires restent rares. Une barrière importante au déploiement du PV dans le bâtiment est clairement lié à l'esthétique encore pauvre des systèmes solaires existants. Il est primordial de trouver des solutions techniques qui permettent une intégration architecturale optimale des capteurs solaires dans le bâtiment afin de préserver notre patrimoine construit et l’esthétique globale de nos villes.Le challenge se trouve donc essentiellement dans la mises au point de moyens technologiques qui permettent de modifier l’apparence d’un panneau solaire, en modifiant au minimum son procédé de fabrication, permettant ainsi de garder les coûts de production au plus bas.
Lay summary

Contenu et objectifs du travail de recherche

Le projet poursuivra deux directions de recherche principales :

1. Solutions d’intégration en façade de technologies PV semi-transparentes ou colorées en utilisant des technologies déjà commercialisées ou émergentes.

2. Développement de produits innovants et ultra performants et leur potentiels d’intégration dans le bâtiment.

Contexte scientifique et social du projet de recherche

Dans un effort conjoint entre les développeurs de produits, les architectes et les scientifiques, ce projet vise à fournir de nouvelles solutions pour une utilisation à grande échelle du photovoltaïque, spécialement dans le bâtiment. Il s’agira aussi de mesurer le potentiel des technologies émergentes, à très haut rendement, et de l’impact qu’elles pourront avoir dans la contribution énergétique 2050.

Keywords

Abstract

Building façades in Switzerland could provide up to 3-4 TWh of electricity, with the advantage of balancing better the summer and winter production. The theoretical potential for well-exposed roof is even a factor 5-6 larger . So far “solar façades” have remained a curiosity for various sets of reasons .Roofs systems tend to fulfil no aesthetic criteria with standard modules usually added onto the roofs. In a joint effort of product developers, architects and scientist, this project aims at providing pathways for a wide scale application of PV façade solutions and researching how high efficiency modules could impact the visual aspects of Switzerland. The project will benefit from input of Project 1-3 and provide data to project 6 of the joint project PV-2050
