Long-term stable and highly efficient perovskite solar cells with a formamidinium chloride (FACl) additive

Abstract

Despite the power conversion efficiency (PCE) in organometal halide perovskite solar cells (PSCs) has achieved 25.2%, the control of the crystallization process and its impact on film quality is still...

Precursor Engineering of the Electron Transport Layer for Application in High‐Performance Perovskite Solar Cells

“…[32,33] The additive engineering of perovskite precursors has been performed extensively to increase the crystallinity of optically active perovskite layers and hence, improve the device performance. [34][35][36][37][38][39][40] In this regard, Kim et al investigated the addition of a methylammonium chloride (MACl) precursor to a formamidinium lead iodide (FAPbI 3 ) perovskite, and reported a significant improvement in the quality of the resultant perovskite films in terms of an increased grain size, crystallinity, and photoluminescence lifetime. [34] Zhou et al proposed a perovskite formation mechanism using a formamidine chloride (FACl) dopant, which effectively increased the size and crystallinity of the perovskite crystallites.…”

Solid waste-derived carbon nanomaterials for supercapacitor applications: a recent overview

“…has also been assisted thoroughly to the various applied fields (Fig. 3), such as supercapacitors materials [18][19][20], solar cells [21][22][23], as battery electrode's [24,25], catalyst supports systems for proton exchange membrane fuel cells [26][27][28], and also to develop polymer nanocomposites for various applications [29][30][31] i.e. in drug delivery, bio-imaging [32][33][34], medicinal biology [35][36][37][38], aerospace [39,40], new age weapon technology [41,42] etc.…”

Unraveling All‐Inorganic CsPbI3 and CsPbI2Br Perovskite Thin Films Formation – Black Phase Stabilization by Cs2PbCl2I2 Addition and Flash‐Annealing

“…The unit cell parameters are a =8.838(5) , b =8.584(4) and c =12.464(1) Å, which correspond to a small cell contraction in comparison to pure CsPbI 3 gamma phase. This effect might be due to the 2D‐anchored effect during crystallization and growth or to the partial substitution of iodine by chloride [23,34–38] . The two main sets of peaks observed at ∼14.4 and 28.9° in 2‐Theta suggest a strong preferred orientation along the [00 l] and [hh0] directions even more favorable here in the presence of the 2D phase in comparison to the observations made without it.…”
