Abstract

The industrialization of perovskite (PVK) solar cells (PSCs) necessitates simple manufacturing, cheapness, nontoxicity, high efficiency, and stability. We report an air-processed lead halide PSCs with cheap, nontoxic, stable NiOx and SnO2 as the hole and electron transport layers separately, to meet all the above commercial requests. By preparing the NiOx (water-dispersible) and SnO2 (oil-dispersible) quantum dots (QDs) with good conductivity and energy band matched well with that of PVK, we fabricate inverted PSCs (ITO/NiOx/PVK/SnO2/Ag) with efficiency up to 20.1/14.6% for active areas of 0.0707/1 cm2, under 1 sun simulated illumination with enhanced UV light ratio. The UV-light resistant PSCs reported here will impel their application in the high altitude areas with strong UV light. Importantly, the monodisperse size and dominant (110) plane of SnO2 QDs achieved by controlling the solvothermal parameters, realize the conformal deposition and defect prevention of SnO2, respectively, thus improving the PSC efficiency and stability.

用于实用空气处理过氧化物太阳能电池的共形二氧化锡和氧化镍电荷传输层

要实现过氧化物（PVK）太阳能电池（PSCs）的产业化，就必须做到制造简单、廉价、无毒、高效和稳定。我们报告了一种采用廉价、无毒、稳定的 NiOx 和 SnO2 分别作为空穴传输层和电子传输层的空气处理卤化铅 PSCs，以满足上述所有商业要求。通过制备具有良好导电性且能带与 PVK 非常匹配的 NiOx（水分散性）和 SnO2（油分散性）量子点（QDs），我们制备出了倒置 PSCs（ITO/NiOx/PVK/SnO2/Ag），在增强紫外光比的 1 太阳模拟照明下，活性面积为 0.0707/1 cm2，效率高达 20.1/14.6%。本文报告的抗紫外线 PSCs 将推动其在紫外线较强的高海拔地区的应用。重要的是，通过控制溶解热参数实现了 SnO2 QDs 的单分散尺寸和主 (110) 平面，分别实现了 SnO2 的保形沉积和缺陷预防，从而提高了 PSC 的效率和稳定性。

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.
