TABLE OF CONTENTS November 2015 Volume 14, Issue 11 Editorial Research Highlights News and Views Review Letters Articles Subscribe   Facebook   RSS   Recommend to library   Twitter   Advertisement Nature Energy: Call for Papers Launching in January 2016, Nature Energy is now open for submissions and inviting high-quality research from across the natural and social sciences. The journal will be dedicated to exploring all aspects of the on-going discussion of energy provision; from the generation and storage of energy, to its distribution and management, the needs and demands of the different actors, and the impacts that energy technologies and policies have on societies. Submit your next research paper to the journal.     Editorial Top A checklist for photovoltaic research   p1073 doi:10.1038/nmat4473 To aid the reproducibility of published results for photovoltaic devices, from now on we will ask authors of relevant manuscripts to complete a checklist of key technical information that must be reported.
