    In order to design a new type of an organic solar cell device and to contribute for its performance optimization, i.e. transport and optical properties, a composite organic solar cell have been designed. It has been fabricated in two modifications from poly(3-hexylthiophene) and [6,6]-phenyl C 61-butyric acid methyl ester mixtures (P3HT:PCBM) and two chiral photosensitive liquid crystalline (PCLC) materials used as additives. Doping of the P3HT:PCBM solar cell by a specific PCLCs led to a distinct adjustment (increase or decrease) of power conversion efficiency in comparison to that of an undoped cell and it is also strongly depends on the viscosity of the PEDOT:PSS used. In order to control the properties of the resulting composite P3HT:PCBM solar cells doped by PCLCs, the photovoltaic and impedance spectroscopy studies have been done for active layers annealed at different temperatures.
