Abstract The basic physicochemical properties and molecular structure of bis-(thrimethylsiloxy). phthalocyaninato silicon [SiPc(OSiMe3)2] are investigated. The temperature of melting of this complex was measured by the DSC method in the temperature interval 20–520 °C (Tm =497 °C). Thermogravimetric analysis data showed mass loss occurs in the temperature range 275−500 °C. The mass loss in this temperature range is 96 %. Mass spectrometric studies of the composition of the gaseous phase of [SiPc(OSiMe3)2] was performed in the temperature range up to 450 °C. It was found that the complex is sublimated in monomeric form. The vapor pressure of the compound was determined as a function of temperature by the Knudsen effusion method. Based on the data obtained, the thermodynamic parameters of the sublimation process are calculated. The X-ray diffraction study revealed that molecular geometric parameters of [SiPc(OSiMe3)2] are varied slightly upon changing of temperature. The photovoltaic properties of [SiPc(OSiMe3)2] studied with heterojunction solar cell of configuration of ITO/complex /C60/Bphen/Al. The operating characteristics of the cell turned out comparable with the characteristics of earlier designed analogues devices based on phthalocyanine complexes of Cu, Zn and Sn.
