Dye adsorption on Ti02and electron transport in Ti02film are the two critical factors in determining efficiency of the the dye sensitized solar cell (DSSC). Increasing dye adsorption which increases the light harvesting is usually achieved by using nanoporous or nanoparticle Ti02films. Electron transport is determined by the inter-particle resistance of Ti02film. Electrospinning is a viable method for forming porous structure materials with high surface area. In this study, it was found that electrospinning is able to achieve good solar cell performance due to the high electron transport caused by the pores in the Ti02film.

AbstractWe report on highly efficient molecular organic light-emitting diodes (MOLEDs) using two novel silole derivatives as emissive and electron transport materials. A silole derivative, namely 2,5-di-(3-biphenyl)-1,1-dimethyl-3,4-diphenylsilacyclopentadiene (PPSPP), which shows blue fluorescence with a high photoluminescence quantum yield of 85% in the solid state, was used as the emissive material. Another silole derivative, namely 2,5-bis-(2‘2“-bipyridin-6-yl)-1,1- dimethyl-3,4-diphenylsilacyclopentadiene (PyPySPyPy), that exhibits a non-dispersive high electron mobility of 2x10-4 cm2/Vsec was used as the electron transport material. MOLEDs using these two siloles and a common hole transport material show blue-green emission centered at 495 nm. This red-shifted electroluminescence (EL) band relative to the blue fluorescence of PPSPP is assigned to a PPSPP:NPB exciplex. A low operating voltage of 4.5 V was measured at a luminance of 100 cd/m2 and an EL quantum efficiency of 3.4% was achieved at 100 A/m2. To our knowledge, this is the highest EL quantum efficiency ever reported based on exciplex emission.
