Perovskite solar cells with atomically coherent interlayers on SnO₂ electrodes

An atomically coherent interlayer between the electron-transporting and perovskite layers in perovskite solar cells enhances charge extraction and transport from the perovskite, enabling high power conversion efficiency.

Controlled growth of perovskite layers with volatile alkylammonium chlorides

In situ grazing-incidence wide-angle X-ray diffraction and scanning electron microscopy were used to evaluate the crystallization process and surface morphology of perovskite thin films coated with alkylammonium chlorides, which were used to fabricate high-efficiency perovskite solar cells.

Multi-layering of a nanopatterned TiO₂ layer for highly efficient solid-state solar cells

A facile process to prepare multi-layered nanopatterned photoanodes (MNPs) is presented with well-arrayed mesoporous inorganic oxide layers. The MNPs were prepared by multiple stacking of nanopatterned TiO₂ layers using a sacrificial polystyrene-thin film layer, which not only guided the stacking TiO₂ layer but also was removed completely by calcination without generating cracks. The MNPs were applied to solid-state solar cells, to exhibit an enhancement of 73% and a 65% in J_sc and power conversion efficiency (PCE), respectively.

A universal approach for the synthesis of mesoporous gold, palladium and platinum films for applications in electrocatalysis

Mesoporous metal films are used in many electrochemical applications. This protocol describes how to make mesoporous Au, Pt and Pd films using micelle templates and provides examples of how to use them (glucose detection and catalysis for alcohol oxidation).

Construction of a photothermal Venus flytrap from conductive polymer bimorphs

A photothermally foldable soft bimorph was prepared by dry transfer of poly(3,4-ethylenedioxythiophene)s (PEDOT) onto poly(dimethylsiloxane) film. The reversible folding nature of the soft bimorph was programmable to convert the two-dimensional (2D) array of bimorph into complex three-dimensional (3D) architectures such as Venus flytrap under light. These 3D structures were returned reversibly to the original unfolded 2D structures under dark. The Venus flytrap could perform a task to snap and move an object within few second of near-infrared exposure. A localized heat pocket was generated inside the folding structure due to the large photothermal effect of PEDOT.
