NOVELTY - The solar cell comprises a photoactive region (06) having polycrystalline organic or inorganic form and predefined diffusion length, and charge carriers, which are separated from photogenerated charge carrier pairs (08) through electrostatic field force and are transported towards outer electrodes (05, 07). An incorporation of local electrostatic fields (02) independent of the photogenerated charge carrier pair is carried out into the photoactive region, where the electrostatic fields have dimensions in the range of the diffusion length.    USE - Used as solar cell.    ADVANTAGE - The solar cell can be economically produced with improved efficiency.    DETAILED DESCRIPTION - The solar cell comprises a photoactive region (06) having polycrystalline organic or inorganic form and predefined diffusion length, and charge carriers, which are separated from photogenerated charge carrier pairs (08) through electrostatic field force and are transported towards outer electrodes (05, 07). An incorporation of local electrostatic fields (02) independent of the photogenerated charge carrier pair is carried out into the photoactive region, where the electrostatic fields have dimensions in the range of the diffusion length. A permanent alignment of the polarity of all local electrostatic fields adjustable in its grade is carried out in the direction of the external electrode. The incorporation of ferroelectric dipoles (03) is carried out in a photoactive area as homogeneous particle addition or as single- or multi-layered application. The alignment of the ferroelectric dipole is carried out through initial or permanent activation of electrodes external of the photoactive areas. The incorporation of oxides with solid charges, oxygen errors, oxygen cluster or lattice defect in the photoactive area with polycrystalline inorganic form. The alignment of the polarity of the local electrostatic field is carried out through a gradient in the charge distribution over the total photoactive area. The incorporation of the local electrostatic field to further electrostatic field flux is carried out on photoactive layer.
