Synthesis of polyphosphazenes as potential photorefractive materials

TL;DR: In this article, a new series of polyorganophosphazenes have been designed for potential photorefractive effect and synthesized via a nucleophilic substitution reaction of poly(dichloroph phosphazene) with N -(6-Hydroxyhexanyl) carbazole (HCZ) as charge-transporting agent, N -6-hydroxyhexanol)-3-(4-Nitrophenylazo)carbazole(HNACZ) was used as electro-optical chromophore.

Graphene/silicon carbide Schottky junction based photovoltaic cell and preparation method thereof

TL;DR: In this paper, a graphene/silicon carbide Schottky junction-based photovoltaic cell and a preparation method for its preparation is presented, which comprises the following steps: placing a TiPdAg back electrode, an n-type monocrystalline silicon piece n-Si, an annular SiO2 layer, and an ANNular gold film from bottom to top in a laminating mode, and forming stepped holes by an inner hole of the gold film, a through hole in the middle of the SiO 2 layer and the upper surface
Journal ArticleDOI

A facile route to the synthesis of reduced graphene oxide-wrapped octahedral Cu2O with enhanced photocatalytic and photovoltaic performance

TL;DR: In this article, reduced graphene oxide (rGO)-wrapped octahedral Cu2O composites (GCCs) were successfully produced by an ultrasonication-assisted reduction of graphene oxide.
Journal ArticleDOI
