In recent years, organic–inorganic hybrid perovskite solar cells (PSCs) have attracted extensive attention due to their high power conversion efficiency (PCE) and simple preparation process. The selection optimization of the hole transport layer (HTL) are very important for device performance. Compared other HTLs, nickel oxide (NiOx) has been widely used in PSCs its good chemical stability, mobility, method. This review begins with application NiOx HTL planar systematically introduces...
Abstract Pure‐phase α‐FAPbI 3 quantum dots (QDs) are the focus of an increasing interest in photovoltaics due to their superior ambient stability, large absorption coefficient, and long charge‐carrier lifetime. However, trap states induced by ligand‐exchange process limit photovoltaic performances. Here, a simple post treatment using methylamine thiocyanate is developed reconstruct FAPbI ‐QD film surface, which MAPbI capping layer with thickness 6.2 nm formed on top. This planar perovskite...
The modification with 4-iodophenylboronic acid (4-IPBA) is optimal due to the strongest coordination Ni vacancies and best energy level alignment perovskite.
Abstract Perovskite planar heterojunction is reported to promote charge‐carrier separation at the interface due introduced built‐in potential, leading improved harvesting. However, possible diffusion of charge carriers along film lateral will increase their travel distance respective electrodes, resulting in increased recombination probabilities. Constructing independent transport channels for positive and negative individually an efficient way optimize perovskite layer thereby achieve...
Given the advantages of high power conversion efficiencies (PCEs), antisolvent-step free production, and suitability for device production in ambient conditions, perovskite solar cells (PSCs) based on ionic-liquid solvents have attained particular research interest. To further improve performance, light management could be optimized to increase harvesting layer. Here, ordered honeycomb-like TiO2 (Hc-TiO2 ) structures with a periodicity around 450 nm were fabricated through sacrificial...
Abstract Perovskite nanocrystals (PNCs) with unique and excellent optical properties have emerged as appealing luminescent materials in optoelectronic fields. However, high temperature processing, complicated procedures, the use of toxic solvents are typically involved preparation PNCs their related devices. In this study, a one‐step method is developed for flexible photoluminescence gel based on at ambient conditions, which promising alternative to current strategy terms experimental...
The combination of all-inorganic perovskites (PVSKs) and polymers allows for free-standing flexible optoelectronic devices. However, solubility difference the PVSK precursors concerns over compatibility between polymer carriers PVSKs imply a great challenge to incorporate different kinds into matrices by same manufacturing process. In this work, are introduced poly(2-hydroxyethyl acrylate) (PHEA) hydrogels in sequence, which PVSK-gel composites achieved with full-color emissions simply...
