Let There Be Light

Solar RRL is entering its third year and we have good reasons to be optimistic about 2019. Since its launch in 2017, the journal has published 264 manuscripts in 24 issues and the acceptance rate is well below 40%. In the past year, the number of submitted and published papers increased by more than 30%, which reflects the positive uptake of the journal from the scientific community. In line with the journal's name, Solar RRL - Rapid Research Letters, one of our main objectives is the quick publication of results, often in rapidly advancing and competitive research areas such as perovskite solar cells. Our other popular topics include OPVs (including non-fullerene and polymer solar cells), photocatalysis, silicon, and thin film solar cells (see Figure 1). The articles we have published in the past two years have received quite a bit of attention and we have summarized the ten top cited ones in Table 1. Some of the content was also highlighted on our news platforms Advanced Science News and Materials Views China. The articles published in Solar RRL have already been cited more than 600 times to date, proving the high visibility of the young journal. Concerning the journal's indexing, Solar RRL is currently covered by Clarivate Analytics Emerging Sources Citation Index (ESCI), which means complete international coverage of articles and citations. The content of the first 24 issues was freely accessible for everyone in 2017 and 2018 but this introductory period has now come to an end, and reading the journal will only be possible through a subscription or institutional/national access. While there is free access to all manuscripts published in this first issue, if you wish to continue reading the excellent work published in Solar RRL going forward, please encourage your institute's librarian to organize a subscription. You can do this by completing the recommendation form here. We are especially thankful to all our faithful readers, reviewers, and authors who continue to send us high quality content. Special thanks are directed, of course, to our valued Editorial Advisory Board members (EABs) for their exceptional submissions and for providing both support and advice. Three of our EABs have kindly shared their personal experiences publishing with Solar RRL (see Figure 2). We thank them for their nice words. In 2019, the editorial staff of Solar RRL is looking forward to getting in touch with our EABs, readers, and well-known or future authors at various events and conferences. Furthermore, we are working on several Special Issues covering a vast range of top quality topics. There is a lot we can look forward to in 2019 and we wish you all the best for a productive and successful year.
