Origin of photoresponse in black phosphorus phototransistors
(Amer Physical Soc, 2014-08-29)
We study the origin of a photocurrent generated in doped multilayer black phosphorus (BP) phototransistors, and find that it is dominated by thermally driven thermoelectric and bolometric processes. The experimentally ...
Up-conversion mechanisms in Er3+-doped fluoroindate glasses under 1550 nm excitation for enhancing photocurrent of crystalline silicon solar cell
In this work, Er3+-containing fluoroindate glasses were synthesized by the conventional melt-quenching method varying Er3+ content from 0.1 to 7 mol%. The series of fluoroindate glass were investigated according to their ...
Effect of the electrolyte cations and anions on the photocurrent of dodecylsulphate doped polypyrrole films
(Elsevier Science BvAmsterdamHolanda, 2002)
Action spectra of EE and SE illumiaated polypyrrole-dodecylsulphate films in aqueous solutions
(Elsevier Science BvAmsterdamHolanda, 2000)
Photocurrent in bulk heterojunction solar cells with similar electron and hole mean free path
(American Institute of Physics - AIPCollege Park, 2013-11)
We present photocurrents at several temperatures carried out in a bulk heterojunction photovoltaic device. To explain the results, we developed an analytical model assuming non-injecting contacts and equal mean free paths ...
Surface Plasmon-Induced Band Gap in the Photocurrent Response of Organic Solar Cells
(HINDAWI PUBLISHING CORPORATION, 2010)
A 260 nm layer of organic bulk heterojunction blend of the polymer poly(3-hexylthiophene) (P3HT) and the fullerene [6,6]-phenyl C(61)-butyric (PCBM) was spin-coated in between aluminum and gold electrodes, respectively, ...
Enhanced photocurrent in photo-emf experiments in pure and doped absorbing photorefractive crystals
(Optical Soc AmerWashingtonEUA, 2002)
Investigation of charge recombination lifetime in gamma-WO3 films modified with Ag-0 and Pt-0 nanoparticles and its influence on photocurrent density
In this communication, we report the growth of pure gamma-phase tungsten oxide (gamma-WO3) films on a conducting substrate (fluorine-doped tin oxide), followed by heat treatment at 500 A degrees C for 2 h, and finally ...
Effect of the electrolyte composition on the response of a TIO2|CDS-Based Photoanode
(Pergamon-Elsevier Science Ltd., 2014-06)
Sulfide solutions are the most widely selected electrolyte for the photoelectrochemical characterization of metal chalcogenide (like CdS and CdSe) based solar cells because its good hole scavenging properties and improved ...
