| There has been a great deal of interest in developing new materials for the fabrication of light emitting diodes (OLEDs). We have prepared a range of intensely metal complexes, which have found application in both monochromatic and white OLEDs. Our approach has involved a systematic study of a range of different materials. We have used a similar approach to develop materials for organic photovoltaic devices (OPVs). I will discuss the development of new materials as donors, acceptors and buffer layers in OPVs. In particular, I will discuss the use of heavy metal complexes and subphthalocyanines as donor materials in organic solar cells and M(acac)3 complexes as buffer layers in OPVs. These complexes can have high molar absorptivities, carrier conductivities and exciton diffusion lengths, all important parameters in designing high efficiency solar cells. |
