Electrochemical Fabrication and Characterization of p-CuSCN/n-Fe2O3 Heterojunction Devices for Hydrogen Production

Bouhjar, Feriel; Ullah, Shafi; Mollar García, Miguel Alfonso; Marí, B.; Bessais, Brahim (The Electrochemical Society, 2017)

[EN] p-CuSCN/n-Fe2O3 heterojunctions were electrochemically prepared by sequentially depositing alpha-Fe2O3 and CuSCN films on FTO (SnO2:F) substrates. Both alpha-Fe2O3 and CuSCN films and alpha-Fe2O3/CuSCN heterojunctions ...
Electrochemical Fabrication and Characterization of p-CuSCn/n-ZnO Heterojunction Devices

Marí Soucase, Bernabé; Singh, Krishan Chander; Ortiz Moya, Laura; Mollar García, Miguel Alfonso (Springer Verlag (Germany), 2013-03)

[EN] p-CuSCN/n-ZnO heterojunction devices were prepared by depositing CuSCN electrochemically over a ZnO film previously deposited. The compact and smooth surface films of n-ZnO on FTO substrate were deposited electrochemically ...
Electrochemical recovery of zinc from the spent pickling baths coming from the hot dip galvanizing industry. Potentiostatic operation

Carrillo Abad, Jorge; García Gabaldón, Montserrat; Ortega Navarro, Emma María; Pérez-Herranz, Valentín (Elsevier, 2011-09)

An electrochemical reactor was developed to recover zinc from the spent pickling solutions coming from the hot dip galvanizing industry. These solutions mainly contain ZnCl2 and FeCl2 in aqueous HCl media. The effect of ...
Electrochemical Synthesis of an Organic Thermoelectric Power Generator

Serrano-Claumarchirant. José F.; Brotons-Alcázar, Isaac; Culebras, M.; Sanchis Sánchez, María Jesús; Cantarero, A.; Muñoz-Espí, Rafael; Gomez, C.M. (American Chemical Society, 2020-10-14)

[EN] Energy harvesting through residual heat is considered one of the most promising ways to power wearable devices. In this work, thermoelectric textiles were prepared by coating the fabrics, first with multiple-wall ...
Influence of a Compact Fe2O3 Layer on the Photovoltaic Performance of Perovskite-Based Solar Cells

Bouhjar, F.; Mollar García, Miguel Alfonso; Ullah, Shafi; Marí, B.; Bessais, B. (The Electrochemical Society, 2018)

[EN] In this study, uniform and dense iron oxide ¿-Fe2O3 thin films were used as an electron-transport layer (ETL) in CH3NH3PbI3-based perovskite solar cells (PSCs), replacing the Titanium dioxide (TiO2) ETL conventionally ...
Influence of Deposition Potential on Structure of ZnO Nanowires Synthesized in Track-Etched Membranes

Pruna, Alina Iuliana; Pullini, Daniele; Busquets Mataix, David Jerónimo (Electrochemical Society, 2012)

Single-crystal ZnO nanowires long up to several microns were fabricated by one-step electrochemical deposition. A template-based process employing track-etched polycarbonate (TE-PC) membranes was used for this purpose. The ...
Low-cost kesterite (CZTS) bilayers as an effective hole-transport layer for perovskite solar cells

Bouhjar, Feriel; Derbali, Lotfi; Khattak, Yousaf Hameed; Marí, B. (Elsevier, 2024-01)

[EN] This study investigates the utility of Copper Zinc Tin Sulfide (CZTS) thin films as inorganic hole-transporting layers (HTLs) in low-temperature perovskite solar cells (PSCs). The primary goal is to improve power ...
Performance of graphene oxide-modified electrodeposited ZnO/Cu2O heterojunction solar cells

Rosas-Laverde, Nelly Maria; Pruna, Alina Iuliana; Cembrero Gil, Jesús; Orozco-Messana, Javier; Manjón, Francisco-Javier (Elsevier, 2019-12)

[EN] We report the fabrication of ZnO/Cu2O heterojunction solar cells by means of the electrodeposition technique. The effect of electrolyte medium for the ZnO deposition, annealing treatment and interface modification ...
Recovery of zinc from spent pickling solutions using an electrochemical reactor in presence and absence of an anion-exchange membrane: Galvanostatic operation

Carrillo Abad, Jorge; García Gabaldón, Montserrat; Ortega Navarro, Emma María; Pérez-Herranz, Valentín (Elsevier, 2012-09-19)

The performance of a one- and two-compartment electrochemical reactor under galvanostatic control for zinc recovery present in the spent pickling solutions is studied in this paper. These solutions, which mainly contain ...
Single step electrochemical deposition for the fabrication of CZTS kesterite thin films for solar cells

Khattak, Yousaf Hameed; Baig, Faisal; Toura, Hanae; Harabi, Imen; Beg, Saira; Marí, B. (Elsevier, 2019-12-15)

[EN] The high absorption coefficient and direct optical band gap of a kesterite Cu2ZnSnS4 (CZTS) makes it very promising absorber material in the manufacturing of high efficiency and low-cost thin film photovoltaic cells. ...
