EVERPV’s objective is to provide EU with efficient solutions for a sustainable treatment of end-of-life PV panels and recovery of high purity and high integrity materials. Based on the grinding of PV panels waste from the backside and/or the use of IR lamps heating, EVERPV will demonstrate two innovative technologies to delaminate the different layers of the PV panel. Combined with recycling processes, it will enable to recover glass with less than 1% impurities, encapsulant and backsheet polymers with a purity over 99%, and silver with a purity of 99%. Besides, the project will cluster with other EU-funded consortia already addressing the recycling of silicon (e.g. PHOTORAMA) to provide with a global solution. The new delamination technologies will be respectively demonstrated at ENVIE recycling plant and at 9TECH to reach TRL7. The technology demonstrated during EVERPV project targets to process more than 3000 tons of solar panels per year, thus recovering enough raw materials recovered to produce more than 350 000 new panels per year by 2030. EVERPV will finally demonstrate the potential for reusability of recovered materials in several industrial value chains in particular in the PV industry. The project will lead a strategic analysis on the potential of new EoL panels circular value chains based on estimated PV waste generation together with environmental and societal impact assessments. EVERPV has gathered a consortium of 16 participants from 8 countries whose expertise ranges from solar PV materials and recycling processes (CEA, CSEM, ENEA, TEC), recyclers (ENVIE, 9TECH), process industries and materials suppliers (SGB, DTF, DPL, JBR), PV modules manufacturing (VAL), collecting and waste treatment organizations (SOREN, ERION), policy-making, business and training facilitators (SPE, UNITAR, BI).

Functional films underpin many electronic and opto-electronic devices, including flat panel displays, OLED's, image sensors, thin film photovoltaic solar cells, etc. Of particular importance to these devices are transparent conductive oxide (TCO) films, such as indium tin oxide (ITO) and aluminium-doped zinc oxide (ZAO). The UK market for functional films is expected to rise to 23.4B by 2010. Further substantial gains in productivity would be made, and new markets opened up, if the devices could be deposited directly onto polymeric web in very large throughput reel-to-reel coaters. However, the deposition of TCO films onto webs poses many significant technological challenges. In comparison to glass, polymeric webs are relatively rough, tend to outgas significantly and are thermally sensitive. The latter point particularly poses a problem, because it is generally necessary to perform a post-deposition annealing process (typically at 500 degC) in order to optimise the optical and electrical properties of TCO materials.One potential solution to this problem is to deposit coatings using the newly developed technique of high powered impulse magnetron sputtering (HIPIMS). This process involves the application of very large power pulses to magnetron sputter cathodes for short periods of time. The peak pulse power can be in the megawatt range and the pulse duration is typically of the order of 80-160 micro seconds, at repetition rates in the range of 10s to 100s of Hz. Initial studies of the HIPIMS (also referred to as high power pulsed magnetron sputtering / HPPMS) system have shown that this intense pulse creates a high degree of ionization (up to 70% for titanium) of the sputtered species with this technique (in contrast to conventional magnetron sputtering, where usually less than 1% of the sputtered material is ionized).The degree of ionization of the sputtered species in HIPIMS is comparable to that produced in cathodic arc discharges; however, with HIPIMS macroparticles are not normally produced. Another important consideration is that, due to the very low duty cycles (~1%) and long off times, the total heat load to the substrate can be very significantly (5-10 times) lower than in conventional DC and pulsed DC sputtering. Thus, the potential for HIPIMS is to harness the high degree of ionization to produce films with significantly improved properties, whilst maintaining a suitably low (sub-150 degC) substrate bulk temperature, allowing a diverse range of substrate materials to be coated. The introduction of HIPIMS technology, therefore, has the potential to provide a step-change in the performance of functional films, such as TCO's, deposited onto polymeric webs. This project will offer the first opportunity to study this new, complex deposition process in detail in both a development-scale system at MMU and an industrial pilot scale reel-to-reel coater at Oxford University. An additional key element of the project will be a detailed study of the nature of the discharge. Plasma characteristics such as the spatial and temporal evolution of the concentrations and temperatures of the species and their power loading of the substrate will be determined using an array of time-resolved diagnostic tools and well developed optical imaging techniques. The ability to deposit fully dense TCO coatings with optimised properties onto flexible substrates would be a major breakthrough and would represent a significant advancement in web coating technology.

A transformation is currently underway in a large range of computer and sensing technologies, displays and communication systems with the introduction of new low cost, flexible molecular and macromolecular materials. These materials, which encompass polymers, advanced liquid crystals, and nanostructures, including carbon and silicon nanowires, are set to have a disruptive impact on current technologies not only because of their cost/performance advantages, but also because they can be manufactured in more flexible ways, provide more functionality and be engineered for a wider range of applications. The new materials have a strong research base in the UK, are suitable for a wide range of commercial concerns, both large and small, and hence provide an important opportunity for UK plc. At Cambridge there has been considerable research and development into these materials in recent years, with a range of world leading results having been achieved, which have in turn been exploited, in more than 15 spin-outs to date. The market penetration of soft materials into microelectronics and photonics however has only just begun, and with a market estimate measured in $10's of billion per annum, it is certain that the UK must capitalise on its strength in the basic science. There is an urgent need for the development of advanced manufacturing technologies using new macromolecular material systems and valid exploitation models. What the UK lacks is a dedicated centre of excellence that can act as a repository of expertise, developing both clear and differentiated core competencies, together with providing a knowledge development and transfer role. Success here will critically depend upon early traction between those in research and those in commercial exploitation. It will also rely on funding of products right through to pilot production for the first time, the lack of which has been a barrier to commercialisation and hence has limited exploitation in this field in the past. This proposal therefore seeks to create a new molecular and macromolecular materials (MMM) IKC. This will bring together the main research activities in the field at Cambridge, namely in the Electrical Engineering Division (in particular within the Centre for Advanced Electronics and Photonics, CAPE) and in the Cavendish. Together this research spans the MMM field and is recognised as having a world-leading position. A key to this proposed IKC however is that it will also allow much greater interaction and collaboration with those in business than has previously been possible for EPSRC funded research activities. Hence the IKC, if awarded, would allow the creation of tightly focussed commercialisation activities jointly with the Judge Business School, the Institute of Manufacturing (including the EPSRC Innovative Manufacturing Research Centre) and the Centre for Business Research. These will allow the creation of a range of innovative knowledge transfer activities spanning business research, training and specific product exploitation. Finally, the Centre will also allow the secondment of researchers from industry and other universities to the IKC, specifically for knowledge transfer (as opposed to research), and in its later stages make use of the provision of pilot manufacturing lines for prototyping. Reciprocal arrangements will also ensure that academics learn the key features of and improve their effectiveness in exploitation themselves.
