Abstract

Cuprous oxide (Cu₂O) is naturally p-type, which has prevented an efficient Cu₂O solar cell. n-Type doping of Cu₂O is demonstrated during electrochemical deposition by adding a chlorine (Cl) precursor to the aqueous solution. Current-voltage characterization reveals that the resistivity of undoped Cu₂O by electrochemical deposition is ∼40 M ωcm, while that of electrochemically doped Cu₂O with Cl is significantly reduced to as low as ∼7 ω cm. X-ray diffraction confirms that the films are pure Cu₂O. Photocurrent measurements verify that Cl-doped Cu₂O is n-type. The solution-based doping method is particularly suitable for low-cost, large-area, and high-throughput fabrication of Cu₂O solar cells.
