High-Performance Photovoltaic Behavior of Oriented Purple Membrane Polymer Composite Films

Interface investigation and engineering – achieving high performance polymer photovoltaic devices†‡

The contact between the polymer active layer and the electrode is one the most critical interfaces in polymer solar cells. In this article, we report the progress of interface engineering in polymer solar cell research, where the multiple functions of the interfacial materials will be discussed. The vertical composition profile in polymer:fullerene blends is an emerging topic, and the interlaye...

Piezoelectric Biopolymer–Polymer Composite Films and Microfibers

258 is one where the piezoactivity and mechanical properties can be altered individually so that the mechanical stiffness of the material can be controlled for particular applications or tuned to match that of the surroundings (e.g., air or water) for increased transduction sensitivity. Here, we present a new piezoelectric material based on a helical biopolymer with an inherently large electric...

Palladium composite membrane with high reversibility of CO2 poisoning

A palladium membrane was prepared using the electroless plating technique (ELP) for the separation and purification of hydrogen from a gas mixture. Depending on operating conditions, hydrogen flux from the membrane was in the range of 0.012-0.023 mol.m-2.s-1. The membrane performance in the presence of CO2 was investigated. The results of the GC analysis showed that at a feed concentration of 1...

Charge Transport in Carbon Nanotubes-Polymer Composite Photovoltaic Cells

We investigate the dark and illuminated current density-voltage (J/V) characteristics of poly(2-methoxy-5-(2-ethylhexyloxy)1-4-phenylenevinylene) (MEHPPV)/single-walled carbon nanotubes (SWNTs) composite photovoltaic cells. Using an exponential band tail model, the conduction mechanism has been analysed for polymer only devices and composite devices, in terms of space charge limited current (SC...
