Abstract

The crystallographic orientation of perovskite crystals significantly influences their photoelectric performance and associated photovoltaic devices. The classic perovskite (MAPbI3) films based on solution processing usually suffer from chaotic orientations. The impact of preferential crystallographic orientation of MAPbI3 thin films on the carrier transport is still far from being well understood. In comparison with the (011) and (111) facets, our density functional theory results revealed that the hole carrier in the (001) facet exhibits superior carrier transport properties. Herein, the highly oriented (001) FAPbI3 could serve as growth templates and promote the (002) orientations of MAPbI3 perovskite. Furthermore, the p-type doping in MAPbI3 was obtained by controlling the amount of MAI. The (002)-dominated MAPbI3 perovskite with p-type characteristics exhibits exceptional carrier transport properties, thereby enhancing device performance.

基于（002）面曝光的p型ma基钙钛矿太阳能电池的实现

钙钛矿晶体的晶体取向显著影响其光电性能和相关的光伏器件。基于溶液处理的经典钙钛矿（MAPbI3）薄膜通常存在混沌取向。MAPbI3薄膜的优先晶体取向对载流子输运的影响尚不清楚。与（011）和（111）面相比，我们的密度泛函理论结果表明（001）面的空穴载流子表现出优越的载流子输运特性。高取向的（001）FAPbI3可以作为生长模板，促进MAPbI3钙钛矿的（002）取向。此外，通过控制MAI的用量，获得了MAPbI3中的p型掺杂。具有p型特征的（002）主导的MAPbI3钙钛矿表现出优异的载流子输运特性，从而提高了器件性能。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
