Abstract In the field of polymer‐based photovoltaic cells, poly(3‐hexylthiophene) (P3HT) and 1‐(3‐methoxycarbonyl)propyl‐1‐phenyl[6,6]C 61 (PCBM) are, to date, most‐studied active materials around world for bulk‐heterojunction structure. Various power‐conversion efficiencies are reported up approximately 5%. This Research News article is focused on a survey tremendous literature published between 2002 2010 that exhibits solar cells based blends P3HT PCBM.
Many thin-film optoelectronic devices use electrodes made of tin-doped indium oxide (ITO), which is acceptably conductive, as well virtually transparent and colorless. Regrettably, an uncommon element its price continues to rise, so it increasingly important recover ITO from that are no longer needed. Previous work has shown simple sonication in neutral water can separate intact other components typical devices, the active separated by ionic buffer layer...
The first set of phenoxy BsubNc compounds, PhO-Cl n and F5-Cl BsubNc, was synthesized through an axial displacement reaction Cl-Cl with phenol pentafluorophenol (respectively). Like their precursor, the products were found to be alloyed mixture phenoxylated Cl BsubNcs random positioning in solid state yet consistent frequency bay position chlorination. average chlorine occupancy determined 0.99 single crystal diffraction BsubNc. Although phenoxylation did not influence chromophore...
In the fabrication of thin-film electronic devices such as solar cells, molecular components are often deposited from solution by spin-coating. Toxic chlorinated solvents widely used in this process, and environmentally benign alternatives desirable. Ideally, these should be inexpensive, derived renewable sources, able to dissolve typical materials. Moreover, they allow creation thin films which interdiffusion different can controlled optimize performance resulting device. an initial survey,...
Organic thin-film optoelectronic devices, unlike inorganic analogues, offer the attractive prospect of large, flexible, and inexpensive arrays made by simple procedures such as roll-to-roll printing. In current organic layers tin-doped indium oxide (ITO) are widely used electrodes. Motivated increasing price high cost ITO-coated substrates, we have examined ways to recover recycle ITO substrates in typical devices environmentally benign methods. A process using only water yields recovered...
Chloro(chloro)nboron subnaphthalocyanine (Cl–ClnBsubNc) from a commercial source and two synthetic routes were each tested as electron-donating hole-transporting materials in planar well bulk heterojunction (PHJ BHJ) organic photovoltaic (OPV) devices. We have previously reported that Cl–ClnBsubNc sample is mixed alloyed composition, wherein has varying degree of bay-position chlorination. determined increasing bay chlorination beneficial effect on the fill factor PHJs. Comparison between...
Controlled synthesis of the electroluminescent polymer PFO-MEH-PPV (poly[(9,9-dioctyl-2,7-divinylenefluorenylene)-alt-co-(2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylene)]) provided samples varying molecular weight (Mw) in range 20–360 kDa, as determined by gel-permeation chromatography and light scattering. The were used active layers organic light-emitting diodes (OLEDs), performance devices was examined a function Mw. Turn-on voltages fell 1.92–2.78 V, luminances varied from 231 to 5826 cd/m...
We compared the performances of polymer-based photovoltaic devices prepared from different formulations poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS). The PEDOT:PSS buffer layer is incorporated between indium tin oxide (ITO) electrode and active layer, which composed a blend poly(3-hexylthiophene) (P3HT) [6,6]-phenyl-C61-butyric acid methyl ester (PCBM). A highest efficiency 3.86% (under AM1.5 solar illumination) was achieved for device trade-named high conductivity...
