Copper (I) oxide (Cu<sub>2</sup>) based solar cells - a review

Copper oxide as inorganic hole transport material for lead halide perovskite based solar cells

“…The first attempt to use this material for PV application was done by national science foundation and joint centre for graduate studies in 1978 (Abdu and Musa, 2009). Since then various techniques were used to fabricate schottky junction, hetero-junction, and homo-junction devices using Cu 2 O as a light harvester (Minami et al, 2014;McShane et al, 2010;Nishi et al, 2012).…”

CuOx/a‐Si:H heterojunction thin‐film solar cell with an n‐type µc‐Si:H depletion‐assisting layer

“…The transition of impurity states has also been reported to convert Cu 2 O films into n-type materials with increased oxygen vacancies, although the mechanism is yet to be clearly demonstrated. In recent studies, n-Cu 2 O films were fabricated by electro-chemical deposition when the pH level or substrate materials were altered [14][15][16]. Therefore, Cu 2 O films have great potential to be used as low-loss p-type or n-type junction layers in Si-based thin-film solar cells, and it is important to develop a range of methods and process conditions for the fabrication of Cu 2 O films.…”

Oxidation behavior of Cu nanoparticles embedded into semiconductive TiO2 matrix

“…As summarized in [11] or [14], copper oxides have been fabricated by various techniques during the last decade: e.g. by chemical vapor deposition, thermal oxidation, electro-deposition, reactive sputtering, etc.…”
