Organic Electrochemical Transistor Microplate for Real-Time Cell Culture Monitoring
A microplate with a multielectrode array of 96 organic electrochemical transistors (OECTs) based on the semiconductive polymer poly(3,4-ethylenedioxythio-phene):poly(styrene sulfonic acid) PEDOT:PSS was developed and ...
Physical properties investigation of reduced graphene oxide thin films prepared by material inkjet printing
(Hindawi Publishing Corporation, 2017-08-23)
The article is focused on the study of the optical properties of inkjet-printed graphene oxide (GO) layers by spectroscopic ellipsometry. Due to its unique optical and electrical properties, GO can be used as, for example, ...
Photoelectric Properties of Solar Cells Based on Perovskites
(Czech Technical University in Prague, 2018-03-13)
Here we discuss materials and construction of particular solar cells that could be possible replacement for the current silicon-based photovoltaic cells, and methods of studying their performance. Solar cells based on the ...
Density of bulk trap states of hybrid lead halide perovskite single crystals: temperature modulated space-charge-limited-currents
(Springer Nature, 2019-03-04)
Temperature-modulated space-charge-limited-current spectroscopy (TMSCLC) is applied to quantitatively evaluate the density of trap states in the band-gap with high energy resolution of semiconducting hybrid lead halide ...
Effect of the Side Chains and Anode Material on Thermal Stability and Performance of Bulk-Heterojunction Solar Cells Using DPP(TBFu) 2 Derivatives as Donor Materials
An optimized fabrication of bulk-heterojunction solar cells (BHJ SCs) based on previously reported diketopyrrolopyrrole donor,ethyl-hexylated DPP(TBFu)2,aswellastwonewDPP(TBFu)2derivatives with ethyl-hexyl acetate and ...
Morphology versus Vertical Phase Segregation in Solvent Annealed Small Molecule Bulk Heterojunction Organic Solar Cells
The deep study of solvent annealed small molecules bulk heterojunction organic solar cells based on DPP(TBFu)2 : PC60BM blend is carried out. To reveal the reason of the solvent annealing advantage over the thermal one, ...

(IOP Publishing, 2016-04-07)
In the present paper, DPP(TBFu)2:C60 donor-acceptor composite films were prepared by vacuum co-deposition and the photoelectrical properties of ITO|PEDOT:PSS| DPP(TBFu)2:C60|Al solar cell samples were investigated.
Novel Riboflavin-Inspired Conjugated Bio-Organic Semiconductors
Flavins are known to be extremely versatile, thus enabling routes to innumerable modifications in order to obtain desired properties. Thus, in the present paper, the group of bio-inspired conjugated materials based on the ...
Aerosol Flow Homogenization in the Spray Polyphenylene Vinylene Thin Film Deposition
(IOP Publishing, 2014-05-15)
Two different spray deposition (SD) techniques were compared on polyvinylene (MDMO-PPV) used as a model material. SD and homogenized (h-SD) techniques were compared. Films of about 1 micron thickness were prepared by SD ...
Vacuum Deposited Diphenyl-Diketo-Pyrrolopyrroles Structures with Photoelectrical Application
(IOP Publishing Ltd, 2014-05-15)
ITO|composite|Al structures with active DPP-C60 composite films (ratio 60:40 mass %) of about 100 nm thicknesses were prepared. The surface morphology of the films was studied by SEM imaging, which revealed uniform films ...
