Research Abstract	This study concerns development of near IR-absorbing materials, directed to the construction of high efficiency dye-sensitized solar cells, which is expected to open up next generation photovoltaics. The research focus is placed on phthalocyanine assemblies being used as near IR dyes with the aim to improve the photon absorption capability to longer wavelengths and higher light-to-electricity conversion efficiency. Density functional theory calculations give new criteria for molecular designs to create near IR-absorbing materials, i.e., structural control of intermolecular non-covalent interaction of phthalocyanine dyes.
