This paper simply introduces the DSSC (DSSCs) the latest progress of electrode. The electrode for DSSC photoelectric conversion efficiency and preparation costs, but have great influence on the costly platinum electrode DSSCs large scale application of limits of electrode, carbon reduction due to its low cost, high activity, pv performance is good wait for a characteristic received widespread concern. Our TanSongTing xiangtan university professor of carbon aerogels, carbon black and activated carbon in stainless steel nets on the preparation of flexible substrate for DSSC performance was testing of electrode, through the pv performance testing to study the electrode light physics and photochemical properties. Results show that, with high specific surface area and content of carbon aerogels holes than carbon materials with such as carbon black, graphite better catalytic reduction activities, its catalytic activity even than the surface area is more than twice the preparation of carbon aerogels of electrode of activated carbon, suggesting the carbon aerogels in pore structure and high porosity is more advantageous to the I3 ? in electrolyte and the spread of the interface between the electrode, so as to improve the I3 - in the reduction of electrode speed. So, the holes in carbon aerogels affect carbon aerogels content is the main factor reduction activities. This experiment in order to obtain more big hole content and specific surface area of the carbon aerogel made the research:

1. Between benzene 2 amine, melamine directly join carbon aerogels respectively in the polymerization reaction, and made of electrode wire online, through flexible photovoltaic characteristics, pore size distribution test to compare such that can better get bigger than the surface area of the hole contents and the methods of carbon aerogels.

2. Between benzene 2 amine, melamine made up with different concentrations of respectively, will not doped solution of nitrogen, carbon aerogels tests to soak in comparative efficiency of electrode carbon aerogels preparation methods of flexible.
