The need for novel green energy harvesting and storage materials, with a proven record for scaling and manufacture is real and present. In order to be able to deliver truly sustainable technology, the design of devices need to be full cradle to grave analysis of its carbon credentials. Plastic electronics are ideally suited to produce such devices with some of the lowest carbon footprints. This is further extended during the operational modes by being able to self-power and use low power operational modes. Within the talk we will examine next generation designs for sustainable nanodevices and renewable energy harvesting systems to help reduce the impact on the carbon foot-print. This will include energy harvesting systems that include plastic photovoltaics (OPV, PSC) and Triboelectric nanogenerators (TENG). Examples on the usage of polymers and bio-degradable and/or non-toxic materials to design and fabricate nano-devices to contribute towards a net-zero carbon society will be discussed. The Advanced Technology Institute (ATI) focus on net-zero carbon themes, by developing flexible, wearable, and unobtrusive energy harvesting and nano-storage devices including solar cells, TENGs, and supercapacitors, etc., which will be central to future IoT smart technologies. Such nanodevices can be utilized to embed in infrastructures for higher quality living.
Ravi Silva is the Director of the Advanced Technology Institute (ATI) and Heads the Nano-Electronics Centre (NEC), which is an interdisciplinary research activity. The ATI has over 150 active researchers working on multidiscipline programmes with the NEC being a major research group within the institute. He joined Surrey in 1995. Ravi’s secondary education was in Sri Lanka, after which he joined the Engineering Department at Cambridge University for his undergraduate and postgraduate work. He was a recipient of Cambridge Commonwealth Trust Fellowship while at Cambridge and member of Clare College.
His research has resulted in over 620 presentations at international conferences, and over 600 journal papers, Over 22,000 citations (Google Scholar), and a Google H-factor of 74. In 2002 he was awarded the Charles Vernon Boys Medal by the Institute of Physics, and in 2003 he was awarded the IEE Achievement Award. In 2003 he was also awarded the Albert Einstein Silver Medal and Javed Husain Prize by UNESCO for contributions to electronic devices.In 2003 the largest EPSRC Portfolio award for £6.68M was awarded to Prof. Silva and his team on Integrated Electronics which examined nanoscale design featrues on the optical and photonic device properties. In 2004 by a SRIF award for £4M to set up a Nano-Electronics Centre for multidisciplinary research was awarded and allowed the enhancement of nano-bio activities via the EU Sensation and EU Carbio programme. Prof. Silva was also a member of the Electrical and Electronic Panel (UoA24) for the Research Assessment Exercise (2003-2008) RAE2008, EPSRC Nanotechnology Task Force and sat (2007-2010) on the Engineering and Physical Sciences Research Council’s (EPSRC) Technology Opportunities Panel (TOP). In 2009 he was elected as a Fellow of the National Academy of Sciences Sri Lanka. He is a panel member in Engineering for the REF2021. In 2008 he was elected a Fellow of the Royal Academy of Engineering, UK.
Prof. Silva was on the advisory board of Imprimatur Ltd and the National Nanotechnology Initiative (NNI) of Sri Lanka. He acted as an Advisor to the Honourable Minister of Science and Technology in Sri Lanka and helped set up the Sri Lanka Institute of NanoTechnology (SLINTec).
He was awarded the Royal Society Clifford Patterson Award for 2011. In 2014 he was awarded a premium medal by the Institute of Engineering and Technology (IET), the JJ Thompson Medal for contributions to Electrical and Electronic Engineering. In 2015, he won the Institute of Materials, Minerals & Mining (IOM3) premium award, the Platinum Medal for contributing to materials science, technology, and industry. In 2016, the Government of Sri Lanka Presidential Award in recognition for many contributions in the field of nanotechnology. In March 2018, he was elected the joint Editor-in-Chief of Wiley’s Energy and Environmental Materials. He was elected as a Commander of the British Empire (CBE) by Her Majesty the Queen in the 2021 New Year Honours list.
