Organo-metal halide perovskite solar cells based on planar architecture have been reported to achieve remarkably high power conversion efficiency (PCE, >16%), rendering them highly competitive the conventional silicon cells. A thorough understanding of role each component in and their effects as a whole is still required for further improvement PCE. In this work, heterojunction-based were simulated with program AMPS (analysis microelectronic photonic structures)-1D. Simulation results...
The corrosive anions (e.g., Cl-) have been recognized as the origins to cause severe corrosion of anode during seawater electrolysis, while in experiments it is found that natural (~0.41 M usually more than simulated (~0.5 Cl-). Here we elucidate besides Cl-, Br- even harmful Ni-based anodes because inferior resistance and faster kinetics bromide chloride. Experimental results reveal Cl- corrodes locally form narrow-deep pits etches extensively generate shallow-wide pits, which can be...

An amphiphilic surfactant, oleamide, was applied to dope the PCBM electron transport layer (ETL) of inverted structure perovskite solar cells (ISPSCs), resulting in a dramatic efficiency enhancement. Under optimized oleamide doping ratio 5.0 wt %, power conversion CH3NH3PbIxCl3-x perovskite-based ISPSC device is enhanced from 10.05% 12.69%, and this primarily due increases both fill factor short-circuit current. According surface morphology study perovskite/PCBM bilayer film, improves...
To develop novel hole-transporting materials (HTMs) is an important issue of perovskite solar cells (PSCs), especially favoring the stability improvement and cost reduction. Herein, we use ternary quantum dots (QDs) as HTM in mesoporous TiO2/CH3NH3PbI3/HTM/Au cell, modify surface CuInS2 QDs by cation exchange to improve carrier transport.

Although lead halide perovskites are demonstrated to be promising photocatalysts for hydrogen evolution from splitting, it still remains challenging fabricate efficient and stable catalysts. Here MoS2 nanoflowers with abundant active sites assembled methylammonium iodide (MAPbI3) microcrystals form a new heterostructure.

Abstract Photoelectrochemical catalysis is an attractive way to provide direct hydrogen production from solar energy. However, conversion efficiencies are hindered by the fact that light harvesting has so far been of limited efficiency in near-infrared region as compared visible and ultraviolet regions. Here we introduce near-infrared-active photoanodes feature lattice-matched morphological hetero-nanostructures, a strategy improves energy increasing light-harvesting spectral range charge...
