Energy Research Outlook. What to Look for in 2018

solar cells, solar fuels, electrochemical energy storage, supercapacitors, display devices, electrocatalysis, photocatalysis, plasmonics, along with theory and modeling.In addition to research articles, Perspectives, and Reviews, we have published Viewpoints and Energy Focus articles as part of the editorial matter to provide a platform for community-wide discussions.We have also jointly published with our sister journals Virtual Issues on lead-free perovskite solar cells, 1 perovskite nanocrystals, 2 and redox flow batteries. 3s a part of our first anniversary celebration, we introduced the Energy Express feature to facilitate rapid communication of major breakthroughs in research.All these efforts have made ACS Energy Letters one of the premier journals in the energy research field in a very short time.The impact of published articles can be seen by the large number of downloads and citations by our readers.
