Event Info Tan Chin Tuan Centennial Professorship Lecture Speaker Professor Subodh G. Mhaisalkar (Tan Chin Tuan Centennial Professor, College of Engineering, School of Materials Science & Engineering, Executive-Director, Energy Research Institute @ NTU) About the Talk The Paris Agreement, a global agreement in reduction of climate change, represents a historic transition to a low-carbon society and a key step to averting the catastrophic effects of global warming and sea-level rise. The Paris Agreement is a decisive step towards renewable energy, efficient buildings and transportation, and a shift away from fossil fuels that contribute significantly towards climate change. While Singapore depends mainly on imported oil and gas to meet its energy demand, and is acknowledged as being an alternative-energy disadvantaged economy, Singapore has set the target of stopping any increase to its greenhouse gas emissions by 2030. It also pledged to reduce its energy intensity by 36 per cent from 2005 levels by 2030 by pursuing energy efficiency in both industrial and residential sectors, improving public transport, and increasing renewable energy deployment. With land scarcity and low wind / tidal resource compared with temperate climates, solar photovoltaics deployment is one of the key opportunities for Singapore. Photovoltaics deployment is however, tempered by rain, clouds, lack of roof top space, and shadowing due to high urban density. These challenges require new approaches including deployment of solar cells on reservoirs or open sea as well as new solutions for building integrated photovoltaics. It is in this context that nanoscience & nanotechnology are poised to play a transformative role with solutions uniquely suited for energy generation and storage. Past five years has witnessed an unprecedented advance in solar cells made from pervoskite semiconductors that form nearly defect free, crystalline films at low temperatures, long-range charge transport, and efficient charge collection, yielding solar cells that rival the performance of industry standard silicon, with record efficiency of 21%. This presentation will outline the sustainability challenges for a tropical megacity like Singapore and will also highlight opportunities for perovskite solar cells in deployments in tandem solar cells, building integrated photovoltaics, and indoor energy harvesting. About the Speaker Professor Subodh Mhaisalkar is the Tan Chin Tuan Centennial Professor in the College of Engineering, School of Materials Science & Engineering at the Nanyang Technological University (NTU), Singapore. Professor Mhaisalkar is also the Executive Director of the Energy Research Institute @ NTU (ERI@N), a pan-University multidisciplinary research institute for innovative energy solutions.
