The efficiency and stability issues of perovskite light-emitting diodes, especially at high brightness, need to be urgently solved for displays and lighting applications. Herein we present a simple chemical washing method called solvent sieve to resolve the phase dimension issue of metal halide perovski...
Irreversible ion migration from the perovskite layer to the charge transport layer and metal electrodes causes irreversible efficiency loss in perovskite solar cells. Confining the mobile ions within the perovskite layer is a promising strategy to improv
Toward Efficient and Stable Perovskite Solar Cells: Choosing Appropriate Passivator to Specific Defectsdefectsnonradiative recombinationpassivationperovskite solar cellsstabilitiesWith a certificated record efficiency of 25.2%, organometal halide perovskites (OHP) solar cells have experienced unprecedentedly rapid ...
Perovskite solar cells (PSCs) offer low costs and high power conversion efficiency. However, the lack of long-term stability, primarily stemming from the interfacial defects and the susceptible metal electrodes, hinders their practical application. In the past few years, two-dimensional (2D) materia...
Defect passivation by tuning grain size and grain boundary (GB) is an effective strategy to reduce the defects on GBs and film surface. Herein, recent progress in the passivation strategy for perovskite films is summarized, including nonstoichiometric passivation, iodide vacancies filling, dimensional ...
Research into the use of perovskite materials as solar cells has boomed in the last several years, following reports of high energy conversion efficiencies, which have continued to climb. New research reveals how to improve the lifetime of these solar cells.Harika...
29 When realizing a stable BSF at the electrode buffer that is distinguished from c-silicon, it requires compatible materials and relevant low-temperature processing due to the soft crystal lattice of halide perovskite. Moreover, while traditional interface engineering mostly focuses only on one side...
Perovskite solar cells (PSCs) have been demonstrated as one of the most promising candidates for solar energy harvesting. Here, for the first time, a functionalized nanographene (perthiolated tri-sulfur-annulated hexa-peri-hexabenzocoronene, TSHBC) is employed as the hole transporting material (HT...
As a result, the AR PPFC films increase the power conversion efficiency of flexible perovskite solar cells (F-PSCs) from 18.6% to 20.4%, and improve the long-term stability of F-PSCs in humid environments. Download: Download high-res image (366KB) Download: Download full-size image...
