Experimental - curves of p-Cu₂O/ZnO film (HTG) HJs in darkness. Inset shows the measured transmittance of the prepared samples after annealing. ITO-coated glass substrate after AZO (150 nm) layer deposition (structure A), with an additional ZnO film (HTG) (300 nm) (structure B), and with a Cu₂O layer (500 nm) atop structure B (structure C).
