Photovoltaic properties of Cu₂O-based heterojunction solar cells using n-type oxide semiconductor nano thin films prepared by low damage magnetron sputtering method

Abstract

We improved the photovoltaic properties of Cu2O-based heterojunction solar cells using n-type oxide semiconductor thin films prepared by a sputtering apparatus with our newly developed multi-chamber system. We also obtained the highest efficiency (3.21%) in an AZO/p-Cu2O heterojunction solar cell prepared with optimized pre-sputtering conditions using our newly developed multi-chamber sputtering system. This value achieves the same or higher characteristics than AZO/Cu2O solar cells with a similar structure prepared by the pulse laser deposition method.

Study of Anticancer Properties of Graphene Oxide–Metal Oxide Composite

“…Cuprous oxide (Cu 2 O) is a well-known p-type semiconductor with a narrow band gap of 2.0-2.2 eV, high optical absorption. It exhibits fast recombination of the photo-generated electron-hole pairs and therefore can be used in photocatalysis, high performance electrode, solar cell, hydrogen production, [17][18][19] organic contamination degradation under visible light, [20,21] etc. Further, Cu 2 O is less toxic, abundant, inexpensive, and easily manufactured which makes it prime candidate for the decomposition of water and degradation of organic pollutants.…”

Numerical modeling and analysis of AZO/Cu2O transparent solar cell with a TiO2 buffer layer

“…Among these oxides, cuprous oxide (Cu 2 O) is considered as one of the most promising p-type semiconductor materials, particularly for photovoltaic applications, thanks to its native p-type semiconductivity, its high majority carrier mobility, and its optical transparency [4][5][6]. As a result, over the past decade, many Cu 2 O-based solar cells that incorporated various n-type semiconductors with large band gap energy, such as aluminum-doped zinc oxide (AZO), have been fabricated with a power conversion efficiency (PCE) between 0.24 % and 3.21 % [7][8][9][10][11]. Despite efforts to fabricate high-performance Cu 2 O/AZO heterojunction solar cells, the achieved efficiencies remain significantly lower than the theoretical limit of 20 %, based on the Cu 2 O band gap [12].…”

Tunning of Templated CuWO4 Nanorods Arrays Thickness to Improve Photoanode Water Splitting

“…In 1972, Fujisima and Honda initiated significant progress on inexpensive and renewable energy technology based on the ecofriendly TiO 2 that successfully used solar power [ 1 ]. In addition, several exploitations and explorations of many other materials [ 2 ], structural repair [ 3 ], as well as fabrication techniques have been carried out to increase the performance and quality of a wide range of solar power transformation conversion tools [ 4 , 5 ]. One that is worth examining is the creation of hydrogen fuel using the PEC water splitting procedure that has been proven to be affordable and eco-friendly.…”
