Dye-sensitized Solar Cell Performance And The Electronic Transmission Study

In this dissertation, the property of electron transport and electrochemistry in Dye-sensitizedSolar Cells were investigated, moreover, some performance of DSSCs was simulated in thecomputer。The main works and rusults are as follows:1) Recent research progress in every components of DSSCs por is reviewed. With contrast,the nanocrystalline TiO₂ is prepared by sol-gel and the film is prepared by silk-screen printing inDSSCs shows better performance.2) The property of electron transport and electron recombination are investigated in theory.Some methods were proposed to decrease electron recombination.3) Driving force for electron transport in TiO₂ nano porous films is sumulated in thecomputer. The driving force consists of an electric field component and a component due to thespatially nonuniform concerntration of free electrons in DSSCs.4) Differential equations and boundary conditions about electron distributing in DSSCs areconstructed by analyzing the Ferber's Quasi-1 Dimension model. In the end, a simulation resultabout output property of DSSCs is given.
