ParIS

Passivating contacts for cost-effective and highly efficient IBC solar cells, sub-project: Development of PVD processes for the deposition of amorphous silicon and silicon oxide thin films for use in IBC solar cells

The aim of the PariS project is to develop a poly-Si IBC solar cell with passivating contact structures produced entirely by magnetron sputtering. To this end, the sub-project involves process development and optimization for the in-situ deposition of a multiple stack of aSi and SiOx layers on a pilot-scale PVD sputtering system designed for this project. In this way, in conjunction with subsequent laser structuring, the efficiency of the solar cells is to be increased by >25% compared to the zebra solar cell and the poly-zebra process simplified, combined with an increase in throughput in production.

LUMINOSITY

Large-area uniform industry compatible perovskite solar cell technology

LUMINOSITY aims to bring the technology of flexible perovskite solar cells to commercially relevant production scales using established industrial processes. The aim of the project is the demonstration of roll-to-roll processed photovoltaic modules with an efficiency (PCE) of >20 % on an area of >900 cm². The sub-project deals with the deposition of a high-quality nickel oxide charge carrier layer, which must be adapted to the specific requirements of the cell structure with aluminum-based substrate foil and an electrode layer of fluorinated tin oxide (FTO).

KLIMA UND ENERGIE

1.1 Investment measures to reduce greenhouse gas (GHG) emissions (in CO₂ equivalents) by at least 20 percent combined with an increase in final energy efficiency of at least 10 percent

VON ARDENNE has set itself the goal of significantly reducing its CO₂ emissions. One component of this is the reduction of building-related Scope 2 emissions through energy efficiency measures that go beyond the limits previously required by law as part of the standards of the European Union.  Based on an energy concept that has been developed, an investment plan of measures is being implemented with new concepts for cooling water supply, building heating, energy and lighting control.

BiPro2Scale

Holistic product and process development of scalable bipolar plates for the implementation of innovative fuel cells for CO₂-neutral heavy-duty applications; sub-project: development of coating processes for durable, highly scaled BPP

The project addresses the development of PEM fuel cells for a power range of at least 1 megawatt for air, marine and rail applications as well as for stationary power generation systems. Such power ranges can only be achieved with scaled bipolar plates with a flow field area of at least 1000 cm², for which product and process development must be completely rethought. In the project, new approaches for media supply and distribution, forming and joining processes and sealing concepts are being developed from a product engineering perspective. The sub-project is concerned with the large-surface coating of the joined bipolar plates on the basis of high-performance carbon coatings in order to enable the longest possible lifetime.

Re-PV

Re-PV - Industrial TOPCon Manufacturing Technology for the Re-establishment of European PV Production
Subproject: PVD-based Tunnel Oxides and Si Deposition

In the Re-PV project, leading equipment manufacturers from Germany and the Fraunhofer ISE are collaborating to provide industrial manufacturing technologies for solar cells with tunnel oxide passivating contacts (Tunnel Oxide Passivating Contact, TOPCon) and to further develop the cell structure. The goal is to make the TOPCon technology available with the required technological maturity for the re-establishment of PV production in the European region. The subproject focuses on the in-situ production of the tunnel oxide as well as one-sided deposition and in-situ doping of the silicon layer. Optimized individual processes serve as a prerequisite for cost-effective high-throughput processes.

VaPeroTOP

VaPeroTOP - Industrial Vacuum Processes for Perovskite-Silicon Tandem Solar Cells on TOPCon-Based Subcells
Subproject: Development of scalable PVD-based vacuum processes for interconnection and hole transport layers

The project "VaPeroTOP" focuses on the development of industrially scalable vacuum processes for a perovskite-silicon tandem solar cell on textured TOPCon-based silicon subcells. This involves, on the one hand, adjustments and further development of the silicon subcells as well as the development of the interlayers and hole transport layers of the top cell. The aim is to address a number of still unresolved issues, particularly related to the choice of materials for the functional layers of the perovskite cell, the coupling layers to the silicon subcell, and the most suitable process technologies for these. Within the framework of the subproject, the interconnection layers necessary for bonding the perovskite absorber, as well as the hole transport layer, are to be adapted primarily with regard to achieving good optical and electrical connection between the subcells at the passivating TOPCon front side contact. Based on the results achieved, the optimized process sequences will then be integrated into the production of a resulting complete tandem cell.

TiSPA

TiSPA - Titanium Substitution in PEMWE through Alternative Bipolar Plates with Innovative Thin-Film Coating
Subproject: Scaled Coating Solutions and Plant Concepts

In this project, alternatives to the conventionally titanium-based components in proton exchange membrane (PEM) water electrolyzers (WE) are developed and optimized. The main objectives are cost and material savings as well as simultaneous increases in efficiency and service life. The focus is particularly on reducing the titanium content as well as the precious metal content in the bipolar plates (BPP) or the coatings in PEMWE stacks while maintaining or increasing the service life. The consortium covers the entire value chain from processing the base materials, their coating, to their use in the electrolyzer stack. In the subproject, coating tests of the coating approaches qualified within the consortium as well as further carbon-based coating solutions are carried out on large areas (400 cm²). As a result of the evaluation of the favored coating approaches, the transfer to industrially scalable plant concepts takes place.
