NOVELTY - The organic photoactive component such as an organic solar cell comprises organic layers having a simple-, tandem-, or multiple-cell, two electrodes, where one of the electrodes is arranged on a substrate as top-counter electrode, a photoactive layer system arranged between the electrodes, an undoped, doped or partially doped load carrier transport layer arranged between the electrode and the photoactive layer system, and a passivating layer made of metal oxide arranged between the photoactive layer system and the top-counter electrode.    USE - Used as organic photoactive component such as an organic solar cell.    ADVANTAGE - The organic photoactive component can be simply and economically manufactured with good quality.    DETAILED DESCRIPTION - The organic photoactive component such as an organic solar cell comprises organic layers having a simple-, tandem-, or multiple-cell, two electrodes, where one of the electrodes is arranged on a substrate as top-counter electrode, a photoactive layer system arranged between the electrodes, an undoped, doped or partially doped load carrier transport layer arranged between the electrode and the photoactive layer system, and a passivating layer made of metal oxide arranged between the photoactive layer system and the top-counter electrode. A cavity-layer system is arranged within the cell or between two adjacent cells and changes the optical field distribution within the component. The passivation layer is directly adjacent to the top-counter electrode and is present within the top-counter electrode or a further layer is present between the passivation layer and the top-counter layer. The passivation layer directly limits on the doped, partially doped or undoped transport layer. The passivation layer is partially or completely doped. The photoactive component is pin-single, pin-tandem cell, pin-multiple cell, nip-single cell, nip-tandem cell or nip-multiple cell. The top counter electrode consists of metal, transparent conductive oxide, doped organic layer, organic crystal, conductive polymer and/or air-sensitive electrode material. The component consists of nip, ni, ip, pnip, pni, pip, nipn, nin, ipn, pnipn, pnin or pipn structures. The layers of the layer system of the component are formed as a light trap extending the optical way of the occurring light. The photoactive component is arranged from flexible carrier materials, which are arranged on curved or flexible carrier surfaces. The organic layers consist of polymers and the component is semitransparent in a conscience light wavelength range.
