Abstract

Small-molecule solar cells are demonstrated using Pt and Pd tetraphenylbenzoporphyrin as donor materials. High efficiencies are achieved, and the effects of triplet excited state diffusion are studied. The solubility of these molecules allows for the fabrication of solution processed solar cells with relatively high performance.
