Low Cost Solar Cells with Electrodeposited Cuprous Oxide

Electrodeposited n‐type cuprous oxide cubic nanostructures for liquefied petroleum gas sensing

“…Deposition parameters such as bath pH, temperature, concentration of the constituent ions as well as applied electrode potential and the deposition current density across the electrodes enables the modulation of deposited film characteristics. Among other characteristics, it has been shown that the resultant surface morphology of the thin films is highly sensitive to variation of above parameters . As a semiconductor, the carrier concentration of Cu 2 O is relatively low (∼10 14 –10 15 cm −3 ) .…”

“…Therefore, for optimal sensor performance, careful optimization of surface morphology (both size and shape) and stability of fabricated material over time are important. Electrochemical deposition has been used previously to fabricate nanostructured Cu 2 O thin films and has been utilized for photovoltaic applications . Among the many sensing applications of Cu 2 O (see Table for a summary), microcrystalline p ‐type Cu 2 O thin films fabricated using chemical bath deposition have been used for sensing of Methane and NO 2 gases , while Cu/Cu 2 O nano‐crystalline hollow spheres synthesized using a micro‐wave assisted hydrothermal method has shown the ability to detect NO 2 at room temperature .…”

Metallic and Oxide Electrodeposition

“…One layer containing a positive charge, the other a negative charge [19][20][21][22]. The n-type semiconductor receive radiation hν, thus valence electron is promoted to conduction band.…”

“…Thus in this context the electrodeposition can contribute greatly. This is because the electrodeposition is a method simple, practical and inexpensive to produce both p-type as n-type [21,22]. Representation of a photovoltaic cell using two semiconductor electrodes and an electrolyte.…”

“…Many papers have discussed the dye-sensitized solar cell (DSC) due its promising efficiency in very low cost [19][20][21][22][23][24][25]. In the literature is found cathodic electrodeposition of TiO 2 nanoparticles on the optically transparent fluorine doped tin oxide-coated (FTO) glass [25].…”
