IF：46.859和IF：5.018的期刊，相继刊登了几乎一模一样的两篇论文

2018年1月1日，Nature Energy(IF: 46.859)出版了题为“Systematic investigation of the impact of operation conditions on the degradation behaviour of perovskite solar cells”的论文，作者：Konrad Domanski, Essa A. Alharbi, Anders Hagfeldt, Michael Grätzel & Wolfgang Tress.

论文摘要：

Perovskite solar cells have achieved power-conversion efficiency values approaching those of established photovoltaic technologies, making the reliable assessment of their operational stability the next essential step towards commercialization. Although studies increasingly often involve a form of stability characterization, they are conducted in non-standardized ways, which yields data that are effectively incomparable. Furthermore, stability assessment of a novel material system with its own peculiarities might require an adjustment of common standards. Here, we investigate the effects of different environmental factors and electrical load on the ageing behaviour of perovskite solar cells. On this basis, we comment on our perceived relevance of the different ways these are currently aged. We also demonstrate how the results of the experiments can be distorted and how to avoid the common pitfalls. We hope this work will initiate discussion on how to age perovskite solar cells and facilitate the development of consensus stability measurement protocols.
