Anotācija The bulk heterojunction cell consisting of poly(3-hexylthiophene) (P3HT) as electron donor and [6,6] phenyl C61 butyric acid methylester (PCBM) as electron acceptor is one of the most efficient organic solid state solar cells [1,2]. The main drawback of this blend is its limited spectral range of only 350-650 nm. To widen the spectral range of this cell, the second bulk heterojunction layer consisting of GaOHPc phthalocyanine (GaOHPc) and fullerene (C61(CO2Et)2) was incorporated under P3HT:PCBM layer. Since GaOHPc have a strong and wide intermolecular charge transfer (CT) band around 830 nm and in blend with C61(Co2Et)2 it shifts to 850-860 nm both bulk heterojunction layers have complementary absorption uniformly covering whole spectral range from UV till NIR [3]. The sandwich type samples were prepared on an ITO glass substrate covered by 30 – 50 nm thick PEDOT:PSS layer and followed by GaOHPc: C61(Co2Et)2 blend by spin coating from its solution in chloroform and chlorbenzene mixture. This layer was covered by P3HT: PCBM blend from its solution in chlorbenzene after first layer drying in vacuum. Significant photosensitivity of cell was observed in the 370-900 nm spectral range. Cell heating in vacuum at 100C for 48 hours increases EQE values, open circuit voltages and fill factors of investigated cells.
