Lead halide perovskite solar cells (PSCs) appear to be the ideal future candidate for photovoltaic applications owing rapid development in recent years. The electron transport layers (ETLs) prepared by low-temperature process are essential widespread implementation and large-scale commercialization of PSCs. Here, we report an effective approach producing planar PSCs with Al3+ doped SnO2 ETLs using a solution-processed method. Al dopant enhanced charge behavior increased current density...

All inorganic CsPbI3-xBrx perovskites have been widely used in photodetectors due to their excellent optoelectronic properties and simple preparation processes. Here, high-performance flexible based on are demonstrated, which achieved by a modified solution-processed method. When biased at low voltage of 10 mV, the device yielded fast response speeds (90 μs /110 for CsPbI2Br PDs 100 μs/140 CsPbIBr2 PDs), high on/off ratio 104, detectivity about 1012 Jones. Meanwhile, devices showed...

Despite two-dimensional (2D) Ruddlesden-Popper-phase layered perovskites (RPLPs) exhibiting excellent environmental stability, most solar cells based on 2D RPLP films are fabricated in a controlled inert atmosphere. Meanwhile, the poor charge transport of owing to unfavorable phase arrangement and defects limits efficiency cells. Here, we fabricate high-efficiency ambient air assisted by zwitterion (ZW) additive. We show that ZW additive suppresses formation bottom phases (n ≤ 2) top 3D-like...

Abstract Focusing on the study of phase separation behavior triblock copolymer and linear low-density polyethylene (LLDPE) systems helps to understand influence microstructure properties poly(vinylcyclohexane)-b- poly(ethylene)-b-poly(vinylcyclohexane) (PVCH-PE-PVCH/LLDPE) blends. We prepared a series blends LLDPE PVCH-PE-PVCH explained their compatibility from microstructure. The research findings indicate that despite having similar block compositions, with higher molecular weight exhibits...

Perovskite solar cells (PSCs) based on organometallic halide have received wide attention and been developed rapidly in recent years, the highest power conversion efficiency (PCE) reached 22.1%. However, these materials contain lead (Pb), which is toxic. It of critical importance to find new elements for partially or completely replacing Pb reduce contents. Most works carried out focused CsSnX 3 (X=I, Br), FASnX (FASnI3) 1-x (MAPbI3) x (x=0-1), MASn I (x=0.25, 0.5), FA 0.75 Cs 0.25 0.5 Sn ,...

Abstract Perovskite solar cells (PSCs) have attracted much attention since the first report. Flexible PSCs are one of important development orientations due to its light weight. However, a low temperature process is essential fabricate flexible deformation plastic substrate. Here, pre-crystallization SnO 2 colloids been used deposit electron transport layer PSCs. The photovoltaic performance has optimized through controlling annealing and thickness. A moderate reduces substrates protects...
