La recherche proposée prévoit des études sur les pérovskites à halogénures métalliques dont le but ultime est de réaliser la conversion de l’énergie solaire en énergie électrique à très haute efficacité en utilisant des matériaux bon marchés et abondants. Aussi, ces pérovskites joueront un rôle important dans les futurs systèmes de conversion d'énergie renouvelable ou les combustibles fossils seront remplacés par l’éléctricité généré à partir de la lumière du soleil.
Lay summary

L'avènement récent des cellules photovoltaic basées sur les pérovskites à halogénures métalliques, en particulier CH3NH3PbI3, comme pigment a surpris la communauté photovoltaïque. Ces cellules ont connu une ascension fulgurante dans leur rendement de conversion de 3% il y a environ 5 ans à un rendement certifié de 17,9% à ce jour. Cependant, pour s'assurer des gains supplémenaire d'efficacité une compréhension beaucoup plus approfondie des facteurs qui contrôlent les performances photovoltaïques de ces dispositifs est nécessaire. Actuellement sont à l'étude des configurations plane et mésoscopiques. Le verdict reste ouverte quelle forme de réalisation emportera la victoire dans la course à la performance, bien que ces jours les cellules utilisant des structures mésoscopiques montrent clairement des rendements plus élevés. En outre, jusqu’à present aucun rendement des cellules de configuration planaire a été certifié. Un nombre de défis techniques doivent être abordées dans la mise à l'échelle de ces systèmes au niveau du module. Les etudes lies à la stabilité sont toujours dans  leurs phase initilae et vont devoir être exécutées à plus grande échelle. Ayant été à la pointe de la revolution des cellules perovskites et profitant d’une longue expérience et d’un savoir faire complémentaire dans les domaines clés de la science des matériaux et de la technologie photovoltaïque, les trois laboratoires partenaires de coopération sur ce projet, c'est à dire EPFL-LPI, AMI-Université de Fribourg et le CSEM proposent d'aborder ces questions en étroite coopération. Le résultat du projet aura un impact positif et important sur la réalisation pratique des cellules perovskite et sur leur application commerciale à grande échelle. Il contribuera ainsi au développement des ressources énergétiques renouvelables en Suisse et dans le monde entier.

Lay Summary (English)

Lead
The proposed research envisages studies on metal halide perovskites whose ultimate goal is to realize solar cells from cheap and readily available materials converting sunlight to electric power with very high efficiency. These will play an important role in future renewable energy conversion systems that will replace fossil fuels serving as a source of electricity from sunlight.
Lay summary

The recent advent of photovoltaic cells based on metal halide perovskites, in particular CH3NH3PbI3, as light harvesters has stunned the photovoltaic community, which has witnessed an amazing rise in their conversion efficiency from 3 % some 5 years ago to a certified efficiency of 17.9 % to date. However to ascertain further efficiency gains a much deeper understanding of the factors that control the photovoltaic performance of these devices is required. Currently both planar and mesoscopic cell configurations are being investigated. The verdict remains open which embodiment will be the winner although cells, using mesoscopic scaffolds clearly show higher efficiencies leave alone. Also none of the planar configuration cells has certified their efficiency so far. Practical engineering challenges will have to be met in the scale up of these systems to the module level. Last not least stability studies are still in its infancy and need to be executed on a much larger scale. Benefiting from the long experience and complementary know how in the key areas of material science and photovoltaic technology and having been on the forefront of the perovskite solar cell revolution, the three partner laboratories cooperating on this project, i.e. EPFL-LPI, AMI-University of Fribourg and CSEM propose to tackle these open issues in close cooperation.  The outcome of the project will have a major positive impact on the practical realization of perovskite cells and their wide spread commercial application contributing to the development of renewable energy resources in Switzerland and the world.

Abstract

The recent and unexpected advent of photovolatic cells based on metal halide perovskites, in particular CH3NH3PbI3, as light harvesters has stunned the photovoltaic community which has witnessed an amazing rise in their conversion efficiency from 3 % some 5 years ago to over 16 % in the beginning of 2014.. However to ascertain further efficiency gains a much deeper understanding of the factors that control the photovoltaic performance of these devices is required. Even measuring the cell efficiency correctly is a challenge as the photocurrent voltage curves of such cells exhibit often-enormous hysteresis effects, which so far are only poorly understood. Currently they’re both planar and mesoscopic cell configurations are being investigated. The verdict remains open which embodiment will be the winner although cells, using mesoscopic scaffolds clearly show higher efficiencies leave alone that none of the planar configuration cells has been certified so far. Practical engineering challenges will have to be met in the scale up of these systems to the module level. Last not least stability studies are still in its infancy and need to be executed on a much larger scale. Benefitting from the long experience and complementary know how in the key areas of material science and photovoltaic technology and having been on the forefront of the perovskite solar cell revolution, the three partner laboratories cooperating on this project, i.e. EPFL-LPI, AMI-University of Fribourg and CSEM propose to tackle these open issues in close cooperation. The thrust of their research will be placed on the following tasks:i)Tune the perovskite bandgap by varying the cation or mixed cations of CH3NH3PbX3 perovskite.ii)Asses the effects of substitutional electronic p and n-dopants i.e. mono and trivalent metal ions.iii)Develop new hole transport materials (HTMs) for high device performance and device durability of solid-state devices. Apply revolutionary new concepts to have exceptionally high endurance to ascertain stable PV power output over at least 25 years.iv)Adapt the morphology of the mesoporous oxide (TiO2) scaffold to the new perovskite and hole transport materials. Gyroid mesostructures will be of particular interest as they offer bicontinuous topologies of high porosity. Identify the most promising mesostructure. v)Scrutinize the effect of the oxide scaffold (TiO2, ZrO2, Al2O3 etc.) and in particular the role of interfacial states on the performance of these exciting and promising new devices.vi)Compare planar and mesoscopic embodiments of perovskite solar cells to clearly ascertain their strength and weaknessesvii)Improve the power conversion efficiency (PCE) of perovskite-based cells from currently 16 to at least 18% by reducing optical and electronic losses. viii)Improve durability of perovskite solar cell by stable material development, interface study and optimization, and device encapsulation development. ix)Up-scale laboratory perovskite cells to mini-module size of the solar cell fabrication e.g. the fabrication process development for uniform perovskite layer and HTL layer over large areas, module pattern technology optimization.x)Develop bifacial perovskite sensitized solar cells consisting of transparent front and back electrodes to be as transparent as possible to transmit light to the bottom cell in a tandem cell. The outcome of the project will have a major positive impact on the practical realization of perovskite cells and their wide spread commercial application contributing to the development of renewable energy resources in Switzerland and the world.
