Plastic Electronics embodies an approach to future electronics in their broadest sense (including electronic, optoelectronic and photonic structures, devices and systems) that combines the low temperature, versatile manufacturing attributes of plastics with the functional properties of semiconductors and metals. At its heart is the development, processing and application of advanced materials encompassing molecular electronic materials, low temperature processed metals, metal oxides and novel hybrids. As such it constitutes a challenging and far-ranging training ground in tune with the needs of a wide spectrum of industry and academia alike. The general area is widely recognised as a rapidly developing platform technology with the potential to impact on multiple application sectors, including displays, signage and lighting, large area electronics, energy generation and storage, logistics, advertising and brand security, distributed sensing and medical devices. The field is a growth area, nationally and globally and the booming organic (AMOLED) display and printed electronics industries have been leading the way, with the emerging opportunities in the photonics area - i.e. innovative solid-state lighting, solar (photovoltaics), energy storage and management now following. The world-leading, agenda-setting UK academic PE research, much of it sponsored by EPSRC, offers enormous potential that is critical for the development and growth of this UK technology sector. PE scientists are greatly in demand: both upstream for materials, process and equipment development; and downstream for device fabrication and wide-ranging applications innovation. Although this potential is recognised by UK government and industry, PE makes a major contribution to the Advanced Materials theme identified in Science Minister David Willet's 'eight great technologies', growth is severely limited by the shortage of trained scientists and engineers capable of carrying ideas forward to application. This is confirmed by industry experts who argue that a comprehensive training programme is essential to deliver the workforce of scientists and engineers needed to create a sustainable UK PE Industry. The aim of the PE-CDT is to provide necessary training to develop highly skilled scientists and engineers, capable both of leading development and of contributing growth in a variety of aspects; materials-focused innovation, translation and manufacturing. The CDT brings together three leading academic teams in the PE area: the Imperial groups, with expertise in the synthesis, materials processing, characterisation, photonics and device physics, the Oxford team with expertise in ultrafast spectroscopes probes, meso and nano-structured composites, vacuum processing and up scaling as well as the material scientists and polymer technologists at QMUL. This compact consortium encompasses all the disciplines relevant to PE, including materials physics, optoelectronics, physical chemistry, device engineering and modelling, design, synthesis and processing as well as relevant industrial experience. The programme captures the essentially multidisciplinary nature of PE combining the low temperature, versatile manufacturing attributes of plastics with the functional properties of semiconductors and metals. Yet, to meet the needs of the PE industry, it also puts in place a deep understanding of basic science along with a strong emphasis on professional skills and promoting interdisciplinary learning of high quality, ranging across all areas of plastic electronics.

This project is centred on the development of the materials, device structures, materials processing and PV-panel engineering of excitonic solar cells (ESCs). These have the potential to greatly reduce both materials and also manufacturing costs where the materials, such as organic semiconductors, dyes and metal oxides, can be processed onto low-cost flexible substrates at ambient temperature through direct printing techniques. A major cost reduction is expected to lie in much-reduced capital investment in large scale manufacturing plant in comparison with conventional high vacuum, high temperatures semiconductor processing. There are extensive research programs in the UK and India developing these devices with the objective of the increase in PV efficiency through improved understanding of the fundamental processes occurring in these optoelectronic composites. However, there has been less activity in the UK and India on establishing from this science base a scalable, commercially viable processing protocol for excitonic solar cells. The scope of this UK-India call enables research and development to be undertaken which can pull together the set of activities to enable manufacturing application, and this extends beyond the usual scope of funding schemes accessible to the investigators. This project tackles the challenge to create cost-effective excitonic solar cells through three components: new material synthesis of lower cost materials; processing and development of device (nano)architectures compatible with low process costs; and the scale up towards prototypes which can replicate solar cell performance achieved in the research phase. The team includes leading scientists in the UK and India working on excitonic solar cells. Skills range from material synthesis and processing, device fabrication and modelling, wet processing of large area thin films, and PV panel manufacture and testing. Careful consideration has been made to match and complement the skills on both sides of the UK-India network. Further to this, engagement with industrial partners in both the UK and India will allow access to new materials, substrates etc., and access to trials and testing of demonstration PV panels in the field.

The UK faces a challenge of providing an energy system that is secure, sustainable and affordable. The cost of upgrading the power infrastructure is estimated to be £200bn using a centralised energy generation model. We believe that the Buildings as Power Stations concept can create a whole new manufacturing and business opportunity and dramatically reduce the investment required to create a secure future for the next generation. Even reducing the power infrastructure investment by 10% represents a £20bn UK opportunity which is mirrored across the developed world. So far on our journey we have had substantial impact and SPECIFIC is a key component to ensure commercialisation of these disruptive technologies principally though leadership of demonstration of new technology in the built environment. Research leadership and excellence is backed up by the publishing of 149 papers, international invited conference presentations and an expanding portfolio of 29 patents. A network of over 52 early adopter industrial partners, spanning both large corporates through to a selection of fast moving and innovative SMEs has also been grown. Where no company or market yet exists we have elected to spin two companies out. Alongside this, world class facilities have been created for large scale research and demonstration of product manufacture, including three pilot lines co-located with world class scientific research instrumentation. The opening of the Solcer Demonstration house in July this year is a key milestone; with colleagues at the Welsh School of Architecture (Cardiff) and the construction supply chain, this 'Active House' uses EXISTING technology harnessed in a unique way to generate up to twice as much energy as it uses. Combining solar electric and thermal generation and storage systems the house is globally unique and with a construction cost of under £150k it is affordable. The journey into the next decade brings both challenge and opportunity. We intend to build on the success of the first four years and to deliver critical new technologies to market, including printed photovoltaics at half the current commercial Si cost, safer building scale aqueous batteries delivering the opportunity to time shift renewable generation to demand, and solar thermal integrated storage solutions which create Active Buildings that do not require gas heating. Each of these sectors alone represent a billion pound opportunity and together they create a compelling case for a paradigm shift in our energy matrix from centralised generation and grid distribution to a model of distributed energy generation. This is disruptive technology so accurate market assessment is challenging. However, considering domestic new build in isolation, with 145,000 new UK homes built in 2014 and assuming an average £125k construction cost (proved through the Solcer House project) this translates to a >£1.8bn annual domestic new build opportunity if only 10% of new homes use the Buildings as Powerstations concept. Given it is affordable, environmentally friendly and offers building owners an additional income stream this projection is conservative. The opportunity in retrofit is even larger as is that in commercial and industrial buildings. The associated manufacturing opportunity will create 5000 jobs in the construction supply chain and give the UK, centred in Wales, a 'once in a lifetime opportunity' to lead the world using technology invented, developed, proven and manufactured here. Wales and the UK can be a beacon of leadership for developed and developing nations alike in a new industrial revolution.
