Title

Metal-free and metallated polymers: properties and photovoltaic performance

Language

English

Abstract

We have studied the properties of organic and organometallic polymers based on a similar chemical structure to elucidate the influence of the metal center on the optical and electronic properties of the polymers as well as their photovoltaic performance. Detailed characterization of the optical properties of both polymers is performed and film morphology and photovoltaic performance are compared. Metal-containing polymers exhibit red-shifted absorption and under optimal processing conditions exhibit different film morphology compared with the metal-free ones. Our results indicate that organometallic polymers represent a promising class of compounds for improved performance in photovoltaic cells. Full Paper: Optical and photovoltaic properties of Pt-containing (P1) and metal-free (P1 MF) polymers with similar structures are investigated (see Figure). It is found that incorporation of metal results not only in an additional absorption band but also results in changes in the film morphology and phase separation, and hence a significant improvement in the photovoltaic performance.
