Abstract

Electrochemically deposited Cu{sub 2}O solar cells are receiving growing attention owing to a recent doubling in efficiency. This was enabled by the controlled chemical environment used in depositing doped ZnO layers by atomic layer deposition, which is not well suited to large-scale industrial production. While open air fabrication with atmospheric pressure spatial atomic layer deposition overcomes this limitation, we find that this approach is limited by an inability to remove the detrimental CuO layer that forms on the Cu{sub 2}O surface. Herein, we propose strategies for achieving efficiencies in atmospherically processed cells that are equivalent to the high values achieved in vacuum processed cells.

Enhancement of the open circuit voltage of Cu₂O/Ga₂O₃ heterojunction solar cells through the mitigation of interfacial recombination

Journal Article Chua, Danny; Kim, Sang; Gordon, Roy - AIP Advances

Thin film solar cells were fabricated using cuprous oxide (Cu₂O) absorber layers grown by chemical vapor deposition (CVD) and gallium oxide (Ga₂O₃) buffer layers grown by atomic layer deposition (ALD) on the cuprous oxide CVD films. The in-situ formation of heterojunction in the same deposition system without exposure to oxygen-rich ambient was found to be effective in mitigating the creation of detrimental cupric oxide (CuO) at the interface, resulting in a pristine photovoltaic junction capable of delivering an enhanced open-circuit voltage of 1.78 V. Numerical device simulations of a novel two-layer absorber architecture (CVD-Cu₂O on ECD-Cu₂O) showed promising possibilities (theoreticalmore »« less

Band offsets of n-type electron-selective contacts on cuprous oxide (Cu{sub 2}O) for photovoltaics

Journal Article Lee, Yun; Buonassisi, Tonio; Young, Matthew; ... - Applied Physics Letters

The development of cuprous oxide (Cu{sub 2}O) photovoltaics (PVs) is limited by low device open-circuit voltages. A strong contributing factor to this underperformance is the conduction-band offset between Cu{sub 2}O and its n-type heterojunction partner or electron-selective contact. In the present work, a broad range of possible n-type materials is surveyed, including ZnO, ZnS, Zn(O,S), (Mg,Zn)O, TiO{sub 2}, CdS, and Ga{sub 2}O{sub 3}. Band offsets are determined through X-ray photoelectron spectroscopy and optical bandgap measurements. A majority of these materials is identified as having a negative conduction-band offset with respect to Cu{sub 2}O; the detrimental impact of this on open-circuitmore »« less

Reduced Cu(InGa)Se₂ Thickness in Solar Cells Using a Superstrate Configuration

Technical Report Shafarman, William

This project by the Institute of Energy Conversion (IEC) and the Department of Electrical and Computer Engineering at the University of Delaware sought to develop the technology and underlying science to enable reduced cost of Cu(InGa)Se₂ manufacturing by reducing the thickness of the Cu(InGa)Se₂ absorber layer by half compared to typical production. The approach to achieve this was to use the superstrate cell configuration in which light is incident on the cell through the glass. This structure facilitates optical enhancement approaches needed to achieve high efficiency with Cu(InGa)Se₂ thicknesses less than 1 µm. The primary objective was to demonstrate amore »« less

Atomically Altered Hematite for Highly Efficient Perovskite Tandem Water‐Splitting Devices

Journal Article Gurudayal, ; John, Rohit; Boix, Pablo; ... - ChemSusChem

Abstract Photoelectrochemical (PEC) cells are attractive for storing solar energy in chemical bonds through cleaving of water into oxygen and hydrogen. Although hematite (α‐Fe ₂ O ₃ ) is a promising photoanode material owing to its chemical stability, suitable band gap, low cost, and environmental friendliness, its performance is limited by short carrier lifetimes, poor conductivity, and sluggish kinetics leading to low (solar‐to‐hydrogen) STH efficiency. Herein, we combine solution‐based hydrothermal growth and a post‐growth surface exposure through atomic layer deposition (ALD) to show a dramatic enhancement of the efficiency for water photolysis. These modified photoanodes show a high photocurrent ofmore »« less

Cuprous oxide photovoltaic cells

Conference Trivich, D.; Wang, E.; Komp, R.; ...

Cuprous oxide, with a band gap of 2.0 eV, is an attractive material for solar cells because of low cost and great availability. The current conversion efficiency is 1%, but theoretical estimates are >13%. For various Schottky barriers, e.g., Al/Cu/sub 2/O, it is proposed that the V/sub oc/ is limited by chemical conversion of the junctions to Cu/Cu/sub 2/O junctions, and the model is supported by Auger and ESCA results. It is proposed to avoid the reaction by use of an oxide interlayer as in Al/Al/sub 2/O/sub 3//Cu/sub 2/O, which also gives an MIS structure, but only minimal success hasmore »« less
