Polymer Photonics

Department no more exists, people moved to Polymers for electronics and photonics department


Polymer photonics department dealt with research of novel polymers and polymer systems for potential applications in photonics, particularly in photodiodes, solar cells and light-emitting devices (LEDs), further also memories, optical storage, sensors etc.  This complex interdisciplinary reseach is performed by the research team consisting of experienced scientists in polymer chemistry and physics, young scientists and technicians, and PhD students as well.

This up-to-date research field has attracted a lot of attention world wide. It is stimulated just by potential applications. Advantages of the polymers are their great variability which enables chemical tuning of optical absorption and emission across whole visible spectral region and relatively cheap device fabrication in comparison with corresponding inorganic materials. Easy preparation of thin films using common industrial techniques implies that polymers are suitable for large area photonics and electronics such as large-area light-emitting devices, displays or solar cells. Polymer solar cells are cheap alternative to the silicon ones. In comparison with inorganic materials polymers offer new and untypical applications, for example energetic sources as clothing components based either on fibers or foils, which could be also utilized in building elements.

Novel conjugated polymers and copolymers with targeted properties are synthetized. Synthetic procedures such as Suzuki, Yamammoto or Stille coupling are used, in some cases their modification is neccessary. Monomers for polymer syntheses are usualy prepared in multisteps procedures using common organic synthesis methods.

Novel polymers are studied in both solutions and thin films using whole series of optical, electrical, photoelectrical, electrochemical and spectroelectrochemical methods. Absorption, reflectivity, photoinduced changes, stationary and time-resolved photo- and electro-luminescence, photoconductivity, charge photogeneration and transport are investigated. The results are exploited to design new polymers or for polymer modification, and also in the study of polymer devices (solar cells, LED, etc). Polymer blends and ordered nanoarrays are studied to modify photophysical and electrical properties of thin films with the aim of device efficiency and performance improvement.

Recently, a sophisticated equipment, the glove box system, which enables to perform complex studies of the properties and phenomena mentioned above in an inert atmosphere, was built up in our laboratory. It consists of two independent glove boxes which are interconnected. The first one is used for smaller chemical work, thin polymer film preparation and characterization. It is equipped with integrated spin-coater, vacuum oven and components needed for optical and electrochemical measurements. The second one with integrated evaporator serves for further photophysical and electrical measurements, finalization of organic photovoltaic and light-emitting devices and their characterization. Incorporation or interconnection of photophysical, optical, electrical and electrochemical measuring techniques enable to perform comparative studies in an inert and ambient atmosphere and vacuum.
