Perovskite synthesis out in the open Although methods have been developed that create photoactive black perovskite phase of formamidinium lead iodide (α-FAPbI 3 ), these routes are temperature and humidity sensitive less compatible with large-scale solar cell production. Hui et al. report an alternative route which vertically aligned thin films grown from ionic liquid methylamine formate. Nanoscale channels lower barrier to permeation enable transformation α-FAPbI , even at high room...
The burgeoning demand for clean and energy-efficient fuel cell system requires electrocatalysts to deliver greater activity selectivity.

Novel hierarchical core@shell structured magnetic nanocatalysts of various morphologies involving ternary Cu-based layered double hydroxide CuMgAl-LDH shells and Fe3O4 cores were prepared via one-pot coprecipitation assembly systematically characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning/transmission electron microscopy (SEM/TEM)/high-resolution (HR) TEM, vibrating-sample magnetometry (VSM), H2-temperature programmed reduction (TPR)...
In this report, we propose a concept of lead immobilization to suppress the exposure risk by employing poly(acrylic acid) grafted carbon nanotubes (CNT-PAA) as dopants in preparation perovskite thin films. Due presence large amount carboxyl groups and self-bundling water insoluble CNTs, CNT-PAA exhibited high Pb2+-immobilization capability, allowing them retain components on substrates reduce lead(II) leaching below hazardous waste limit once occasionally exposed water. Moreover, PAA chains...
Lead halide perovskite solar cells (PSCs) have been considered one of the most promising candidates for future energy supply, whereas just cell does not guarantee sustainability. Owing to ionic nature and constituent heavy metals, materials are prone decay under operating conditions pose a threat ecosystems human health, seriously restricting their practical deployment. Herein, we briefly review safe-by-design strategies heal failed PSCs thereby extend operational lifetime recycle lead...
P-i-n type perovskite solar cells (PSCs) manifest some promising advantages in terms of remarkable operational stability, low-temperature processability, and compatibility for multi-junction devices, whereas relatively low efficiency compared to n-i-p PSCs because mismatched energy level alignment poor interface quality at both n- p-type contacts. Recently, great progress has been achieved the p-i-n PSCs, efficiencies exceeding 25% have reported from different research groups. Herein,...
Abstract Perovskite solar cells (PSCs) based on the SnO 2 electron transport layer (ETL) have achieved remarkable photovoltaic efficiency. However, commercial ETLs show various shortcomings. The precursor is prone to agglomeration, resulting in poor morphology with numerous interface defects. Additionally, open circuit voltage ( V oc ) would be constrained by energy level mismatch between and perovskite. And, few studies designed ‐based promote crystal growth of PbI , a crucial prerequisite...
Solar cells based on organometal hybrid perovskites have exhibited promising commercialization potential owing to their high efficiency and low-cost manufacturing. However, the poor outdoor operational stability of perovskite solar restricted practical application, moisture permeation organic compounds volatilization are realized as main factors accelerating performance degradation.

Solar cells based on organic-inorganic hybrid lead-halide perovskites are very promising because of their high performance and solution process feasibility. Elemental engineering perovskite composition is a facile path to obtain high-quality crystals for efficient stable solar cells. It was found that partially substituting I- with Cl- in the precursor promoted crystal growth, grain size larger than layer thickness, facilitated generation self-passivation PbI2. Whereas residual ions were...
Abstract Solution‐processed tin oxide (SnO 2 ) is ubiquitously used as the electron transport layer (ETL) in perovskite solar cells, while main concerns related to application of SnO nanoparticles are self‐aggregation potential and infeasible energy level adjustment, leading inhomogeneous thin films mismatched alignment with perovskite.

The stability of perovskite solar cells, especially at high temperature (85 °C) conditions, is one the most critical aspects to advance practical application. All-inorganic perovskites, by substituting volatile organic compounds with cesium, have exhibited a promising thermal resistance and energy conversion potentials.
