摘要

将实验室规模的钙钛矿太阳能电池转化为大规模生产将需要钙钛矿薄膜的均匀结晶。我们设计了一种方法，通过使用定制的3D打印结构在平方米大小的钙钛矿薄膜上产生明确的三维（3D）层流，来帮助结晶过程。所得钙钛矿太阳能组件面积为0.7906平方米，经认证的功率转换效率为15.0%，符合三套太阳能电池标准。我们对一个峰值功率为0.5兆瓦的钙钛矿太阳能发电场进行了为期一年的运行研究，结果表明，与同一设施的硅组件相比，每千瓦装机容量的发电量高出29%，这主要是由于它们的温度依赖运行特性。

3D laminar flow-assisted crystallization of perovskites for square meter-sized solar modules.

Transforming laboratory-scale perovskite solar cells to large-scale production will require uniform crystallization of the perovskite film. We designed a method to aid the crystallization process by generating well-defined three-dimensional (3D) laminar airflow over square meter-sized perovskite films using a customized 3D-printed structure. The resultant perovskite solar modules with areas of 0.7906 square meters had a certified power conversion efficiency of 15.0% and achieved compliance with three sets of solar cell standards. Our metrics for a 1-year operational study from a 0.5-megawatt peak power perovskite solar farm indicate a 29% higher energy yield per kilowatt of installed capacity compared with that of silicon modules at the same facility that primarily resulted from their temperature-dependent operational characteristics.

期刊介绍： Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research. Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated. Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
