- Abstract
- Photovoltaic and optical properties of composite films of 5,10,15,20-tetraphenylporphyrin (TPP) and graphene (Gr) obtained by spincoating method were investigated. Mesurements of the photovoltage (PV) depending on the mass ratio of TPP and graphene were carried out. The PV values were 1.89, 1.29, 3.0 and 1.51 for TPP:Gr mass ratios of 4:1, 3:2, 2:3, 1:4 correspondingly, and for comparison - 1.39 mV for TPP film. The hypsochromic shift of the Soret band relative to the values for single-component TPP films for TPP:Gr mass ratios of 4:1, 3:2, 2:3, 1:4 was consisted of 0.5, 3.5, 3.0 and 6.5 nm, respectively.
