 R&D Projects

Project: J3019E
Development of Flow Simulation and Process Control Tools for Thermal Spray Coating (FLOSS)  Partners:
Monitor Coatings Ltd, Metallisation Ltd,  

 
As a cost-effective method to produce wear resistant, high temperature corrosion coating products, thermal spraying offers greater thickness capability, no part size restrictions with minimal noxious waste. However, complex multiphase flow generated in thermal spraying makes process control very difficult. Supported by a consortium including coating equipment manufacturers, service providers, end users and research providers, this project has proposed innovative methods to significantly reduce current costs of established high quality coating. Closely aligned with the competition theme, the main objectives of this project are: to simulate the multiphase flow; to develop flow function models integrated with CAE design and simulation tools; to develop a process control database to mininize the operation complexity and improve the quality of coating products.

 

Project: FP7-PEOPLE-IAPP-2008 Marie Curie Action 230715
Computational simulation to enhance technology development of thermal spray coating (SimuSpray) Partners: Southampton University, Pyrogenesis-sa.gr

SIMUSPRAY is to develop a pan European partnership by uniting research activities between a SME and a leading EU university. The latest techniques in computational simulation and surface engineering will be used or developed for  solving industry-focused engineering problems. The use of the state-of-the-art modelling approaches will revolutionise the technology development in protective coating and surface engineering industry.
 

Project: FP7-Energy 241281
Thin Si film based hybrid solar cells on low-cost Si substrates (ThinSi)                       Partners: Stiftelsen SINTEF, Fraunhofer Institute for Solar Energy Systems, Interuniversitair Micro-Electronica centrum VZW, Ente per le Nuove tecnologie, l’Energia e l’Ambiente, University of Nottingham, Oxford Instruments Plasma Technology Ltd, Elkem Solar AS, PyroGenesis S.A, NT-MDT Europe BV, Innovative Materials processing Technologies Ltd, Isofoton S.A.


ThinSi will develop a solar cell processing chain for high throughput, cost-effective manufacturing of thin film silicon based solar cells on low-cost silicon substrates. The substrates will be made on the basis of an innovative powder-to-substrate concept. In line with the Workprogramme topic addressed, it will reduce the cost of solar cell modules compared to those made by the conventional wafer based approach.

A set of innovative processes will be developed to realize the new low-cost concept and transfer the results into production. The new silicon based substrates will be made from low-cost material using state-of-the art ceramics technologies. Cost effective processes for the formation of the thin film silicon base and the complete solar cell structure will be developed. New methods for optical confinement will be investigated. The electronic properties of individual solar cell materials and their interfaces as well as the relationship between the deposition parameters and the device properties will be analyzed using advanced characterization and modeling.

It will also develop a better understanding of relevant materials issues. Manufacturing procedures suitable for pilot scale production will be developed based on an innovative process chain. The produced solar cells will be assembled into complete modules. The project will develop innovative technologies and equipment prototypes that can easily be scaled up and transferred to production lines by the end of the project. New marked opportunities for the SME and industrial partners will be created, both as production tool suppliers and as end-users of the technology.
