A transparent top anode consisting of molybdenum oxide (MoO x ) and silver (Ag) is employed in an “inverted‐illumination” geometry in conjunction with a thick aluminium (100 nm) bottom contact. The optimised MoO x ‐Ag‐MoO x stack (MAMS) has an optical transmission of 80% at the wavelength of 520 nm, sheet resistance of ∼5 ohm sq −1 and yields conversion efficiencies in 5 cm × 5 cm photoactive‐area “sub‐modules” of 3.17% ‐ outperforming the equivalent conventional ITO/PEDOT:PSS devices.
