The Solar Energy Research Institute of Singapore (SERIS) at the National University of Singapore (NUS) is Singapore’s national institute for applied solar energy research. It commenced operations in 2008. SERIS is supported by the National University of Singapore (NUS), the National Research Foundation Singapore (NRF) and the Singapore Economic Development Board (EDB). It has the stature of an NUS University-level Research Institute and is endowed with considerable autonomy and flexibility, including an industry-friendly IP policy. SERIS conducts research, development, testing and consulting on solar energy technologies and their integration into buildings and power systems. The institute’s R&D spectrum covers materials, components, processes, systems and services, with an emphasis on solar photovoltaic cells, modules and systems. SERIS is globally active but focuses on technologies and services for tropical regions, in particular for Singapore and South-East Asia. SERIS’ multi-disciplinary research team includes more than 140 scientists, engineers, technicians and PhD students. In addition, the institute has formal research links with 20 professors from NUS (“Adjunct researchers”). SERIS collaborates closely with universities, research organisations, government agencies and industry, both locally and globally. The collaborations with companies from the global solar sector span from small start-ups to industry leading heavyweights. R&D clusters are: 1. Novel PV Concepts 2. Silicon Solar Cells and Modules 3. PV modules 4. Solar energy systems
