A photovoltaic cell of improved construction may include an active layer comprising first and second active material, and a dye. Either of the first and second active material may include a copper-oxide compound. The active layer may further include a thin-coat interfacial layer, which may coat at least a portion of either of the first and second active material. The dye may include a primary electron donor moiety, a core moiety, and an electron-withdrawing moiety. |
