Dear Fabio Vega Nieto, The Journal of Photonics for Energy will be publishing a Special Section on Hybrid Organic-Inorganic Solar Cells, guest edited by Ana Flavia Nogueira and Garry Rumbles.The submission deadline is 15 September 2014. This special section of JPE will center on the science and technology of hybrid organic-inorganic solar cells, including solid-state organic-inorganic solar cells based on perovskites and other materials; hybrid organic- and polymeric-inorganic photovoltaics (PVs) that contain inorganic materials or carbon Q-dots and nanotubes; or graphene in the active  light-harvesting layer(s) and/or interfaces.  This special section covers topics such as: Nature and dynamics of the photoexcited species Charge carrier mobility Control of the light-harvesting layer(s)' morphology Role(s) of the interfaces and contacts Long-term stability of the devices Chemical composition, size, shape, dispersity, and nature of the inorganic nanoparticles Surface ligands Organic/inorganic interfaces in polymeric-inorganic hybrid photovoltaics Original research work or reviews that address any of the above issues and challenges are welcome. Authors are strongly encouraged to submit an original research paper or a short (10-20 manuscript pages) review article highlighting recent advances in the last 2-3 years in any areas related to this field. See the full call for papers  Manuscripts should be submitted to SPIE according to the journal guidelines with a cover letter indicating that the submission is intended for this special section. All papers submitted for this special section, both solicited and unsolicited, will go through the standard journal review process. The Journal of Photonics for Energy is published in the SPIE Digital Library, with freely searchable abstracts and tables of contents; articles are available via subscription or pay-per-view.
