Abstrakty
EN Poly(indenefluorene) belongs to the exotic and rare group of synthetic, photoactive, macromolecular compounds which may replace crystalline silicon in electronics in the future. Although the attempt of performance improvement it is highly probable that PIF itself is characterized by low exciton diffusion length and therefore (apart from PCBM and TCNQ) application of other electronacceptor in blends with that polymer may be pointless. There is a particular need of application other conjugated polymers with optimized band gap around 1.5 eV. Polymers with lower values of band gap may not deliver satisfying voltages even though they have well absorption properties. The main obstacle in commercial applications of low-band gap polymer based devices is that they have low values of operating currents and external quantum efficiencies. Few available examples of photovoltaic devices based of that kind of polymers manufactured in [3, 4] have EQEs less than 0,01%. New bulks based on other macromolecular chromophores are needed as presented devices based on PIF may be used only as a photonic detector of radiation.
