Abstract
We investigate trivalent doping of tin halide perovskites as a means to decrease p-doping and control defect activity. Through density functional theory calculations and experimental characterization, we demonstrate that doping with scandium, lanthanum, and cerium successfully accomplishes Fermi level upshift, reducing background carrier concentration and defect densities, thereby improving material performance. Solar cell fabrication and testing highlight the doping efficacy, with lanthanum delivering increased photocurrent and open circuit voltage compared to control devices, despite being nonoptimized. This research underscores the potential of cation doping in enhancing the functionality of p-doped tin perovskites for advanced optoelectronic applications.
我们研究了卤化锡包晶石的三价掺杂,将其作为减少 p 掺杂和控制缺陷活性的一种手段。通过密度泛函理论计算和实验表征,我们证明掺杂钪、镧和铈能成功实现费米级上移,降低背景载流子浓度和缺陷密度,从而改善材料性能。太阳能电池的制造和测试凸显了掺杂的功效,与对照器件相比,尽管镧未被优化,但其光电流和开路电压却有所提高。这项研究强调了阳离子掺杂在增强对掺杂锡包晶石功能方面的潜力,可用于先进的光电应用。

期刊介绍:
ACS Energy Letters is a monthly journal that publishes papers reporting new scientific advances in energy research. The journal focuses on topics that are of interest to scientists working in the fundamental and applied sciences. Rapid publication is a central criterion for acceptance, and the journal is known for its quick publication times, with an average of 4-6 weeks from submission to web publication in As Soon As Publishable format.
ACS Energy Letters is ranked as the number one journal in the Web of Science Electrochemistry category. It also ranks within the top 10 journals for Physical Chemistry, Energy & Fuels, and Nanoscience & Nanotechnology.
The journal offers several types of articles, including Letters, Energy Express, Perspectives, Reviews, Editorials, Viewpoints and Energy Focus. Additionally, authors have the option to submit videos that summarize or support the information presented in a Perspective or Review article, which can be highlighted on the journal's website. ACS Energy Letters is abstracted and indexed in Chemical Abstracts Service/SciFinder, EBSCO-summon, PubMed, Web of Science, Scopus and Portico.
