A BHJ-thin-film/liquid-electrolyte based electrochemical-sensor for visible light-detection
Shikoh A.S.; Ahmad Z.; Touati F.; Shakoor R.A.; Bhadra J.; Al-Thani N.J.... more authors ... less authors ( Royal Society of Chemistry , 2017 , Article)The current study presents a new type of inexpensive and very sensitive bulk heterojunction (BHJ) organic photo-sensor (OPS) configuration that incorporates a layer of liquid electrolyte into the conventional BHJ photodiode ... -
Assessing mobile ions contributions to admittance spectra and current-voltage characteristics of 3D and 2D/3D perovskite solar cells
Shikoh A.S.; Paek S.; Polyakov A.Y.; Smirnov N.B.; Shchemerov I.V.; Saranin D.S.; Didenko S.I.; Ahmad Z.; Touati F.; Nazeeruddin M.K.... more authors ... less authors ( Elsevier B.V. , 2020 , Article)Recently, the 2D perovskite layer is employed as a capping/passivating layer in the perovskite solar cells (PSCs). The 2D perovskite layer is prepared by inserting a large-sized hydrophobic cation spacer into the perovskite ... -
Enhancement of electrical and optical performance of N719 by co-sensitization
Shikoh A.S.; Ahmad Z.; Touati F.; Al-Muhtaseb S.A. ( Elsevier B.V. , 2018 , Article)This paper deals with the electrical, optical and electrochemical properties of a metal-free dye C78H74O8 (AS-2), which has been used to improve the photo-detection properties of C58H86N8O8RuS2 (N719) based Dye sensitized ... -
Highly transparent low sheet resistance electrodes for solar cell applications
Shikoh A.; Popelka A.; Touati F.; Benammar M.; Zhu Z.; Mankowski T.; Balakrishnan K.; Mansuripur M.; Falco C.... more authors ... less authors ( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)High aspect ratio copper nanowires were synthesized, using a solution-based approach. The nanowires along with reduced graphene oxide thin films were sprayed onto glass and flexible substrates and later annealed in order ... -
Metal nanowire-graphene composite transparent electrodes
Mankowski T.S.; Zhu Z.; Balakrishnan K.; Shikoh A.S.; Touati F.; Benammar M.; Mansuripur M.; Falco C.M.... more authors ... less authors ( SPIE , 2014 , Conference Paper)Silver nanowires with 40 nm diameter and copper nanowires with 150 nm diameter were synthesized using low-temperature routes, and deposited in combination with ultrathin graphene sheets for use as transparent conductors. ... -
Optimization of ITO glass/TiO2 based DSSC photo-anodes through electrophoretic deposition and sintering techniques
Shikoh A.S.; Ahmad Z.; Touati F.; Shakoor R.A.; Al-Muhtaseb S.A. ( Elsevier Ltd , 2017 , Article)In the current study, TiO2 layers were deposited onto Indium Tin Oxide (ITO) coated glass substrates at varied voltage levels ranging from 2.5 VDC to 7.5 VDC, using Electrophoretic deposition (EPD) process. Subsequently, ... -
Sol-gel deposition and plasma treatment of intrinsic, aluminum-doped and gallium-doped zinc oxide thin films as transparent conductive electrodes
Zhu Z.; Mankowski T.; Balakrishnan K.; Shikoh A.S.; Touati F.; Benammar M.A.; Mansuripur M.; Falco C.M.... more authors ... less authors ( SPIE , 2015 , Conference Paper)Zinc oxide and aluminum/gallium-doped zinc oxide thin films were deposited via sol-gel spin-coating technique. Employing plasma treatment as alternative to post thermal annealing, we found that the morphologies of these ... -
