Cuprous Oxide as an Active Material for Solar Cells

Fabrication and Characterization of Gradient Oxide Thin Films

“…Cu, CuO, and Cu2O have long been studied for their semiconductor properties. Cu metal is highly conductive, while Cu and CuO have band gaps in the visible and near infrared regions, making them attractive for solar applications [24]. CuOx is promising because of its non--toxic nature, abundance, and inexpensive processing [25].…”

“…Researchers have studied methods such as nanowire growth [24], doping [27], and nano cluster growth [22].However, to our best knowledge, little work has been done to form multi--band gap single junctions of oxide thin films. To improve efficiency of CuOx solar cell, we intend to form a multi--band gap gradient Cu/SnOx thin film.…”

Green synthesis of Cu x O nanoscale MOS capacitors processed at low temperatures

“…Cupric oxide (CuO) is also a p-type oxide yet its narrower energy gap (E g =1.5-1.9 eV) inhibits the material transparency unless it was deposited as a very thin layer [3]. Copper oxide (Cu x O) thin films have been prepared by several techniques each of them has its own advantages and disadvantages [4][5][6][7][8]. Structural, optical and electrical properties of the deposited films are very dependent on the method used.…”

Effect of Deposition Time on the Electrodeposited n-Cu₂O Thin Film

“…There are many methods have been applied to synthesize Cu 2 O which include sol-gel approach [6], thermal oxidation [7], chemical vapor deposition [8], sputtering [9] and electrochemical method [5,10]. Compared to mentioned methods, electrochemical method is chosen because the deposition process is simple, inexpensive, producing controllable film thickness, producing large scale deposition and can be done at low temperature [11]. Moreover, it has the facility to control the surface morphologies, phase compositions and other elements by adjusting the deposition parameters [12].…”
