We demonstrate an evaporation-based combinatorial approach for fast screening of precursor combinations for the synthesis of novel perovskite materials. Nine material combinations can be explored simultaneously, which enabled us to synthesize nine different lead-free perovskite compounds. The structural properties (morphology, crystal structure) and optical properties (UV–vis absorption spectra, photoluminescence) of the prepared materials were investigated. Among these materials, several Sn-based and Pd-based perovskites exhibit strong absorption in the visible spectral range and thus may be of interest for photovoltaic applications. In addition, butyl ammonium tin iodide exhibits bright red emission, and it is of interest for potential light emitting applications.

通过组合蒸发合成无铅钙钛矿薄膜:筛选不同前体组合的快速方法

我们展示了一种基于蒸发的组合方法,可快速筛选用于合成新型钙钛矿材料的前体组合。可以同时探索9种材料的组合,这使我们能够合成9种不同的无铅钙钛矿化合物。研究了所制备材料的结构特性(形态,晶体结构)和光学特性(紫外可见吸收光谱,光致发光)。在这些材料中,几种基于Sn的和基于Pd的钙钛矿在可见光谱范围内表现出强吸收性,因此可能在光伏应用中引起人们的兴趣。另外,丁基铵碘化锡表现出亮红色发射,并且对于潜在的发光应用是令人感兴趣的。
